HERBS by Plant Family

Anacardiaceae (the cashew or sumac family) are a family of flowering plants bearing fruits that are drupes and in some cases producing urushiol, an irritant. Anacardiaceae include numerous genera with several of economic importance. Notable plants in this family include cashew (in the type genus Anacardium), mango, poison ivy, sumac, smoke tree, and marula. The genus Pistacia (which includes the pistachio and mastic tree) usually is now included, but has sometimes been placed in its own family, Pistaciaceae.

The Apocynaceae are a family of flowering plants that includes trees, shrubs, herbs, and lianas, commonly called the dogbane family. Members of the family are native to European, Asian, African, Australian and American tropics or subtropics, with some temperate members.

The Aquifoliaceae are a group of about 400 species of primitive asterid flowering plants. Nearly all of these species belong to the genus Ilex, commonly known as the hollies. Most are evergreen trees or shrubs, though there are deciduous species that lose their leaves seasonally. Most Americans and Europeans are familiar with the spiny-leaved species Ilex aquifolium (English holly) or Ilex opaca (American holly), but it is actually uncommon for hollies to produce spines on their leaves.

Arecaceae are a botanical family of perennial lianas and trees commonly known as palms. They are flowering plants, the only family in the monocot order Arecales. Roughly 202 genera with around 2600 species are currently known, most of them restricted to tropical, subtropical, and warm temperate climates. Most palms are distinguished by their large, compound, evergreen leaves arranged at the top of an unbranched stem. However, many palms are exceptions, and in fact exhibit an enormous diversity in physical characteristics. As well as being morphologically diverse, palms also inhabit nearly every type of habitat within their range, from rainforests to deserts.

Bignoniaceae is a family of flowering plants in the order Lamiales. It is not known which of the other families in the order it is most closely related to. Nearly all of the Bignoniaceae are woody plants, but a few are subwoody, either as vines or subshrubs. A few more are herbaceous plants of high elevation montane habitats, in three exclusively herbaceous genera: Tourrettia, Argylia, and Incarvillea. The family includes many lianas, climbing by tendrils, by twining, or rarely, by aerial roots. The largest tribe in the family, called Bignonieae, consists mostly of lianas and is noted for its unique wood anatomy.

Burseraceae is a moderate-sized family of 17-18 genera and about 540 species of flowering plants. The actual numbers differ according to the time period in which a given source is written describing this family. The Burseraceae is also known as the Torchwood family, the frankincense and myrrh family, or simply the incense tree family. The family includes both trees and shrubs, and is native to tropical regions of Africa, Asia and the Americas.

The Caryophyllaceae, commonly called the pink family or carnation family, are a family of flowering plants. It is included in the dicotyledon order Caryophyllales in the APG III system, alongside 33 other families, including Amaranthaceae, Cactaceae, and Polygonaceae. It is a large family, with 86 genera and some 2,200 species. This cosmopolitan family of mostly herbaceous plants is best represented in temperate climates, with a few species growing on tropical mountains. Some of the more commonly known members include pinks and carnations (Dianthus), and firepink and campions (Lychnis and Silene).

Celastraceae (the staff vine or bittersweet family; syn. Canotiaceae, Chingithamnaceae, Euonymaceae, Goupiaceae, Lophopyxidaceae, and Siphonodontaceae in Cronquist system), are a family of about 90-100 genera and 1,300 species of vines, shrubs and small trees, belonging to the order Celastrales. The great majority of the genera are tropical, with only Celastrus (the staff vines), Euonymus (the spindles) and Maytenus widespread in temperate climates.

Asteraceae or Compositae are an exceedingly large and widespread family of Angiospermae. The group has more than 23,000 currently accepted species, spread across 1,620 genera and 12 subfamilies. In terms of numbers of species, Asteraceae is rivaled only by Orchidaceae. The main feature of the family is the composite flower type in the form of capitula surrounded by involucral bracts.The name "Asteraceae" comes from Aster, the most prominent generum in the family, that derives from the Greek ἀστήρ meaning star, and is connected with its inflorescence star form.

Convolvulaceae can be recognized by their funnel-shaped, radially symmetrical corolla; the floral formula for the family has five sepals, five fused petals, five epipetalous stamens (stamens fused to the petals), and a two-part syncarpous and superior gynoecium. The stems of these plants are usually winding, hence their Latin name (from convolvere, "to wind"). The leaves are simple and alternate, without stipules. The fruit can be a capsule, berry, or nut, all containing only two seeds per one locule (one ovule/ovary).

The Cupressaceae or cypress family is a conifer family with worldwide distribution. The family includes 27 to 30 genera (17 monotypic), which include the junipers and redwoods, with about 130-140 species in total. They are monoecious, subdioecious or (rarely) dioecious trees and shrubs from 1–116 m (3–379 ft) tall. The bark of mature trees is commonly orange- to red- brown and of stringy texture, often flaking or peeling in vertical strips, but smooth, scaly or hard and square-cracked in some species.

Cyperaceae are a family of monocotyledonous graminoid flowering plants known as sedges, which superficially resemble grasses or rushes. The family is large, with some 5,500 species described in about 109 genera. These species are widely distributed, with the centers of diversity for the group occurring in tropical Asia and tropical South America. While sedges may be found growing in almost all environments, many are associated with wetlands, or with poor soils. Ecological communities dominated by sedges are known as sedgelands. Features distinguishing members of the sedge family from grasses or rushes are that members of the sedge family have stems with triangular cross-sections (with occasional exceptions), and their leaves are spirally arranged in three ranks (grasses have alternate leaves forming two ranks).

Elaeaocarpaceae is a family of flowering plants. The family approximately contains 605 species of trees and shrubs in 12 genera. The largest genera are Elaeocarpus, with about 350 species, and Sloanea, with about 150. The plants are hermaphrodite or dioecious and bear flowers clustered in inflorescences.

Euphorbiaceae, the Spurge family are a large family of flowering plants with 300 genera and around 7,500 species. Most are herbs, but some, especially in the tropics, are also shrubs or trees. Some are succulent and resemble cacti. This family occurs mainly in the tropics, with the majority of the species in the Indo-Malayan region and tropical America a good second. There is a large variety in tropical Africa, but it is not as abundant or varied as in these two other tropical regions. However, Euphorbia also has many species in non-tropical areas such as the Mediterranean Basin, the Middle East, South Africa, and southern USA.

The Ginkgoaceae is a family of gymnosperms which appeared during the Mesozoic Era, of which the only extant representative is Ginkgo biloba, which is for this reason sometimes regarded as a living fossil. Formerly, however, there were several other genera, and forests of ginkgo existed. Because leaves can take such diverse forms within a single species, these are a poor measure of diversity, but wood structure points to the existence of diverse ginkgo forests in ancient times.

A family of insects in the superfamily Coccoidea (order Hemiptera). They sometimes are called lac insects or lac scales.

The mints, taxonomically known as Lamiaceae or Labiatae, are a family of flowering plants. They have traditionally been considered closely related to Verbenaceae, but in the 1990s, phylogenetic studies suggested that many genera classified in Verbenaceae belong instead in Lamiaceae. The currently accepted version of Verbenaceae may not be more closely related to Lamiaceae than some of the other families in the order Lamiales. It is not yet known which of the families in Lamiales is closest to Lamiaceae.

The Lauraceae are the laurel family, that includes the "True Laurel" and its closest relatives. The family comprises over 3000 species of flowering plants in over 50 genera world-wide. They occur mainly in warm temperate and tropical regions, especially Southeast Asia and South America. Most are aromatic evergreen trees or shrubs, but one or two genera such as Sassafras are deciduous, and Cassytha is a genus of parasitic vines.

The Fabaceae or Leguminosae, commonly known as the legume, pea, or bean family, are a large and economically important family of flowering plants. The group is the third-largest land plant family, behind only the Orchidaceae and Asteraceae, with 730 genera and over 19,400 species. The largest genera are Astragalus (over 2,400 species), Acacia (over 950 species), Indigofera (around 700 species), Crotalaria (around 700 species), and Mimosa (around 500 species).

The Lythraceae are a family of flowering plants, including about 620 species of mostly herbs, with some shrubs and trees, in 31 genera. Major genera include Cuphea (275 spp.), Lagerstroemia (56), Nesaea (50), Rotala (45), and Lythrum (35). Lythraceae have a worldwide distribution, with most species in the tropics, but ranging into temperate climate regions, as well. The family is named after the type genus, Lythrum, the loosestrifes (e.g. Lythrum salicaria purple loosestrife) and also includes henna (Lawsonia inermis). It now includes the pomegranate, formerly classed in a separate family Punicaceae. The family also includes the widely cultivated crape myrtle trees. Botanically, the leaves are usually in pairs (opposite), and the flower petals emerge from the rim of the calyx tube. The petals often appear crumpled.

Malpighiaceae is a family of flowering plants in the order Malpighiales. It comprises approximately 75 genera and 1300 species, all of which are native to the tropics and subtropics. About 80% of the genera and 90% of the species occur in the New World (the Caribbean and the southernmost United States to Argentina) and the rest in the Old World (Africa, Madagascar, and Indomalaya to New Caledonia and the Philippines). One feature that is found in several members of this family, and rarely in others, is providing pollinators with rewards other than pollen or nectar; this is commonly in the form of nutrient oils (resins are offered by Clusiaceae). One feature that is found in several members of this family, and rarely in others, is providing pollinators with rewards other than pollen or nectar; this is commonly in the form of nutrient oils (resins are offered by Clusiaceae).

The Malvaceae are a family of flowering plants containing over 200 genera with close to 2,300 species. Well-known members of this family include okra, cotton, and cacao. The largest genera in terms of number of species include Hibiscus (300 species), Sterculia (250 species), Dombeya (225 species), Pavonia (200 species), and Sida (200 species).

The Mesembryanthemaceae form a major and unique component of southern Africa's arid land flora. Succulent leaves, bright shiny-petalled flowers and hygrochastic fruit (capsules open when it rains) characterize the group. Mesembs are extremely diverse, particularly so in the Succulent Karoo Region, although they have a strong presence in the Fynbos. Some of the more primitive groups are almost entirely confined to Fynbos, suggesting that the Fynbos Biome may have acted as a mesic refuge for the semisucculent members of this group. Mesembs are the subjects of a huge trade in 'curiosity plants' among succulent collectors. They display features not seen elsewhere in the plant kingdom. The combination of minutism, mimicry and extreme succulence accounts for much of the variation in form and bizarre shapes that add to their appeal.

Moraceae are a family of flowering plants comprising about 40 genera and over 1000 species. Most are widespread in tropical and subtropical regions, less so in temperate climates. The only synapomorphy within Moraceae is presence of laticifers and milky sap in all parenchymatous tissues, but generally useful field characters include two carpels sometimes with one reduced, compound inconspicuous flowers, and compound fruits. Included are well-known plants such as the fig, banyan, breadfruit, mulberry, and Osage-orange. The 'flowers' of Moraceae are often pseudanthia (reduced inflorescences).

Myristicaceae is the botanical name for a family of flowering plants. The family is present in Eurasia and the Americas and it has been recognised by most taxonomists; it is sometimes called the "nutmeg family", after its most famous member, Nutmeg (Myristica fragrans). The family consists of about twenty genera, with about 440 species, of trees and shrubs, found in tropical areas across the world. Myristicaceae are woody evergreen plants living in tropical regions. They are present in Brazil, Colombia, Peru, Venezuela, the Caribbean, Guianas, India, Malaysia, Indonesia, Papua New Guinea, Sri Lanka.

The Myrtaceae are a family of dicotyledon plants, placed within the order Myrtales. Myrtle, clove, guava, feijoa, allspice, and eucalyptus belong here. All species are woody, with essential oils, and flower parts in multiples of four or five. One notable character of the family is that the phloem is located on both sides of the xylem, not just outside as in most other plants. The leaves are evergreen, alternate to mostly opposite, simple, and usually with an entire (not toothed) margin. The flowers have a base number of five petals, though in several genera the petals are minute or absent. The stamens are usually very conspicuous, brightly coloured and numerous.

Nymphaeaceae is a family of flowering plants. Members of this family are commonly called water lilies and live in freshwater areas in temperate and tropical climates around the world. The family contains eight genera. There are about 70 species of water lilies around the world. The genus Nymphaea contains about 35 species across the Northern Hemisphere. The genus Victoria contains two species of giant water lilies and can be found in South America. Water lilies are rooted in soil in bodies of water, with leaves and flowers floating on the water surface. The leaves are round, with a radial notch in Nymphaea and Nuphar, but fully circular in Victoria.

Phytolaccaceae is the botanical name for a family of flowering plants. Such a family has been almost universally recognized by taxonomists, although its circumscription has varied. It is also known as the Pokeweed family. The APG II system, of 2003 (unchanged from the APG system, of 1998), also recognizes this family and assigns it to the order Caryophyllales in the clade core eudicots. The family comprises about 16 genera, totalling a hundred species. It is divided into the subfamilies Agdestioideae, Phytolaccoideae, and Rivinioideae by the Takhtajan system.

Pinaceae (the pine family) are trees or shrubs, including many of the well-known conifers of commercial importance such as cedars, firs, hemlocks, larches, pines and spruces. The family is included in the order Pinales, formerly known as Coniferales. Pinaceae are supported as monophyletic by its protein-type sieve cell plastids, pattern of proembryogeny, and lack of bioflavonoids. They are the largest extant conifer family in species diversity, with between 220-250 species (depending on taxonomic opinion) in 11 genera, and the second-largest (after Cupressaceae) in geographical range, found in most of the Northern Hemisphere with the majority of the species in temperate climates but ranging from sub arctic to tropical. The family often forms the dominant component of boreal, coastal and montane forests. One species just crosses the equator in southeast Asia. Major centres of diversity are found in the mountains of southwest China, Mexico, central Japan and California.

The Poaceae (also called Gramineae or true grasses) are a large and nearly ubiquitous family of monocotyledonous flowering plants. With more than 10,000 domesticated and wild species, the Poaceae represent the fifth-largest plant family, following the Orchidaceae, Asteraceae, Fabaceae, and Rubiaceae. Though commonly called "grasses", seagrasses, rushes, and sedges fall outside this family. The rushes and sedges are related to the Poaceae, being members of the order Poales, but the seagrasses are members of order Alismatales. Grasslands are estimated to compose 20% of the vegetation cover of the Earth. Poaceae live in many other habitats, including wetlands, forests, and tundra.

The Polyporaceae are a family of bracket fungi belonging to the Basidiomycota. The flesh of their fruiting bodies varies from soft (as in the case of the Dryad's Saddle illustrated) to very tough. Most members of this family have their hymenium (fertile layer) in vertical pores on the underside of the caps, but some of them have gills (e.g. Panus) or gill-like structures (such as Daedaleopsis, whose elongated pores form a corky labyrinth). Many species are brackets, but others have a definite stipe - for example: Polyporus badius. Most of these fungi have white spore powder but members of the genus Abundisporus have colored spores and produce yellowish spore prints. Cystidia are absent.

Rhamnaceae, the Buckthorn family, are a large family of flowering plants, mostly trees, shrubs and some vines. The family contains 50-60 genera and approximately 870-900 species. Rhamnaceae have a worldwide distribution, but are more common in the subtropical and tropical regions. The earliest fossil evidence of Rhamnaceae is from the Eocene. The simple leaves can be either alternate and spiraling, or opposite. Stipules are present. These leaves are modified into spines in many genera, in some (e.g. Paliurus spina-christi and Colletia cruciata) spectacularly so. Colletia stands out by having two axillary buds instead of one, one developing into a thorn, the other one into a shoot.

Rubiaceae are a family of flowering plants, variously called the coffee family, madder family, or bedstraw family. The group contains many commonly known plants, including the economically important coffee (Coffea), quinine (Cinchona), and gambier (Uncaria), the medicinal ipecacuanha (Carapichea ipecacuanha), and the horticulturally valuable madder (Rubia), west Indian jasmine (Ixora), partridgeberry (Mitchella), Morinda, Gardenia, and Pentas. Members of the coffee family tend to be concentrated in warmer and tropical climates around the world. Currently, about 611 genera and more than 13,000 species are placed in Rubiaceae. This makes it the fourth-largest family of flowering plants by number of species, and fifth-largest by number of genera.

Rutaceae is a family of flowering plants, usually placed in the order Sapindales. Species of the family generally have flowers that divide into four or five parts, usually with strong scents. They range in form and size from herbs to shrubs and small trees. The most economically important genus in the family is Citrus, which includes the orange (C. sinensis), lemon (C. × limon), grapefruit (C. paradisi), and lime (various, mostly C. aurantifolia, the key lime). Boronia is a large Australian genus, some members of which are plants with highly fragrant flowers and are used in commercial oil production. Other large genera include Zanthoxylum, Melicope and Agathosma. There are approximatively 160 genera in the family Rutaceae:List of Rutaceae genera.

Sapindaceae is a family of flowering plants in the order Sapindales. There are about 140–150 genera with 1400–2000 species, including maple, horse chestnut, and lychee. Sapindaceae members occur in temperate to tropical regions, many in laurel forest habitat, throughout the world. Many are lactiferous, i.e. they contain milky sap, and many contain mildly toxic saponins with soap-like qualities in either the foliage and/or the seeds, or roots. The largest genera are Serjania, Paullinia, Acer and Allophylus. The largely temperate genera formerly separated in the families Aceraceae (Acer, Dipteronia) and Hippocastanaceae (Aesculus, Billia, Handeliodendron) were included within a more broadly circumscribed Sapindaceae by the APG. Recent research has confirmed the inclusion of these genera in Sapindaceae.

Many scientists still place the Selaginellales in the class Lycopodiopsida (often misconstructed as "Lycopsida"). This group of plants has for years been included in what, for convenience, was called "fern allies". S. moellendorffii is an important model organism, and its genome was sequenced by the United States Department of Energy's Joint Genome Institute. Selaginella species are creeping or ascendant plants with simple, scale-like leaves (microphylls) on branching stems from which roots also arise. The plants are heterosporous (megaspores and microspores), and have structures called ligules, scale-like outgrowths near the base of the upper surface of each microphyll and sporophyll. Under dry conditions, some species of Selaginella roll into brown balls (a phenomenon known as poikilohydry). In this state, they may be uprooted. Under moist conditions the brown balls become green, because of which these are also known as resurrection plants (as in Selaginella bryopteris).

The Simaroubaceae is a small, mostly tropical, family in the order Sapindales. In recent decades it has been subject to much taxonomic debate, with several small families being split off. A molecular phylogeny of the family was published in 2007, greatly clarifying relationships within the family. The best-known species is the temperate Chinese Tree-of-heaven Ailanthus altissima, which has become a cosmopolitan urban weed tree. Well-known genera in the family include the tropical Quassia and Simarouba.

Styracaceae is a small family of flowering plants in the order Ericales, containing 11 genera and about 160 species of trees and shrubs. The family occurs in warm temperate and subtropical regions of the Northern Hemisphere. The family is characterised by spirally arranged simple leaves with no stipules; symmetrical white flowers with a corolla of 2-5 (-7) fused petals; and the fruit usually a dry capsule, sometimes winged, less often a fleshy drupe, with 1-2 seeds. Most are large shrubs to small trees 3-15 m tall, but Halesia monticola (H. carolina var. monticola) is larger, with trees 39 m tall known in the Great Smoky Mountains National Park in North Carolina, United States. Several genera include species popular as ornamental trees valued for their decorative white flowers. Benzoin resin, used in herbal medicine and perfumes, is extracted from the bark of Styrax species.

Thymelaeaceae are a cosmopolitan family of flowering plants composed of 50 genera (listed below) and 898 species. It was established in 1789 by Antoine Laurent de Jussieu. Thymelaeaceae are in the order Malvales. Except for a sister relationship with Tepuianthaceae, little is known for sure about their relationships with the other families in the order. The family is more diverse in the southern hemisphere than in the northern, with a major concentrations of species in Africa and Australia. The genera are overwhelmingly African. Thymelaeaceae are mostly trees and shrubs, with a few vines and herbaceous plants. Several genera are of economic importance. Gonystylus (Ramin), is valued for its hard, white wood. The bark of Edgeworthia and Wikstroemia is used as a component of paper. Daphne, is grown for its sweetly scented flowers. Species of Wikstroemia, Daphne, Phaleria, Dais, Pimelea and other genera are grown as ornamentals. Many of the species are poisonous if eaten.

The Apiaceae (or Umbelliferae) are a family of mostly aromatic plants with hollow stems. The family is large, with more than 3,700 species spread across 434 genera; it is the 16th-largest family of flowering plants. Included in this family are the well-known plants: angelica, anise, arracacha, asafoetida, caraway, carrot, celery, Centella asiatica, chervil, cicely, coriander (including cilantro), cumin, dill, fennel, hemlock, lovage, Queen Anne's lace, parsley, parsnip, sea holly, and the now extinct silphium.

Zygophyllaceae are a family of flowering plants that contain the bean-caper and caltrop. The family includes around 285 species in 22 genera. In the APG III system of classification, the families Zygophyllaceae and Krameriaceae compose the order Zygophyllales. In the previous version of their classification system, the Angiosperm Phylogeny Group had included the option of placing Krameria within Zygophyllaceae. Zygophyllaceae are divided into five subfamilies. A molecular phylogeny of the family was published in 2000. Phylogenies of groups within the family have also been published. A phylogeny of the southern African species of Zygophyllum was published in 2008. Peganum was in Zygophyllaceae before being moved to the newly created family Nitrariaceae. King Clone, a Creosote bush (Larrea tridentata) in California, is believed to be the oldest living organism.
