Individual species valued for their hard, heavy, dark timber, are commonly known as ebony trees, while others are valued for their fruit and known as persimmon trees. Some are useful as ornamentals and many are of local ecological importance. Species of this genus are generally dioecious, with separate male and female plants.

Agaricus is a genus of mushroom-forming fungi containing both edible and poisonous species, with over 400 members worldwide and possibly again as many disputed or newly discovered species. The genus includes the common ("button") mushroom (A. bisporus) and the field mushroom (A. campestris), the dominant cultivated mushrooms of the West.

Boletus is a genus of mushroom-producing fungi, comprising over 100 species. The genus Boletus was originally broadly defined and described by Carl Linnaeus in 1753, essentially containing all fungi with hymenial pores instead of gills. Since then, other genera have been defined gradually, such as Tylopilus by Petter Adolf Karsten in 1881, and old names such as Leccinum have been resurrected or redefined. Some mushrooms listed in older books as members of the genus have now been placed in separate genera. These include such as Boletus scaber, now Leccinum scabrum, Tylopilus felleus, Chalciporu

Viscum is a genus of over 100 species of mistletoes, native to temperate and tropical regions of Europe, Africa, Asia and Australasia. Traditionally, the genus has been placed in its own family Viscaceae, but recent genetic research by the Angiosperm Phylogeny Group shows this family to be correctly placed within a larger circumscription of the sandalwood family, Santalaceae. Its name is the origin of the English word viscous, after the Latin viscum, a sticky bird lime made from the plants' berries.

Commelina is a genus of approximately 208 species commonly called dayflowers due to the short lives of their flowers. They are less often known as '''widow's tears'. It is by far the largest genus of its family, Commelinaceae.

Monotropa is a genus of four species of herbaceous perennial flowering plants. The genus was formerly classified in the family Monotropaceae and presently classified in Ericaceae. They are native to temperate regions of the Northern Hemisphere and are generally rare. Unlike most plants, they do not have chlorophyll and therefore are non-photosynthetic; they are myco-heterotrophs that obtain food through parasitism on subterranean fungi. Because they do not need any sunlight to live, they can live in very dark sites such as the floor of deep forest. The name "Monotropa" is Greek for "one turn"

Averrhoa is a genus of trees in the family Oxalidaceae. It includes five species native to Java, the Maluku Islands, New Guinea, Sulawesi, and Vietnam. The genus is named after Averroes, a 12th-century astronomer and philosopher from Al-Andalus.

It contains five species of slow-growing shrubs and trees, reaching a height of approximately but usually less than half of that. All are native to subtropical and tropical regions of the Americas and are commonly known as lignum-vitae, guayacán (Spanish), or gaïac (French). The genus name originated in Taíno, the language spoken by the native Taínos of the Bahamas; it was adopted into English in 1533, the first word in that language of American origin.

Pisonia is a genus of flowering plants in the four o'clock flower family, Nyctaginaceae. It was named for Dutch physician and naturalist Willem Piso (1611–1678). Certain species in this genus are known as catchbirdtrees, birdcatcher trees or birdlime trees because they catch birds. The sticky seeds are postulated to be an adaptation of some island species that ensures the dispersal of seeds between islands by attaching them to birds, and also allows the enriching of coralline sands. (Should a fledgling fall to the ground, become entangled in the Pisonia sticky seeds, and be unable to free itse

Isopyrum is a genus of four species of flowering plants of the family Ranunculaceae native to Eurasia. Isopyrum species have white flowers with five sepals and five petals.

They are native to the Americas, ranging from southern Florida and Texas in the United States to Argentina. The highest diversity occurs in Mexico and the Andes. The generic name is derived from the Greek words κιθάρα (kithara), meaning "lyre", and ξύλον (xylon), meaning "wood," referring to the use of the wood in the sounding boards of string instruments. Several species, especially C. caudatum and C. spinosum, are cultivated as ornam

The genus is classified in the tribe Gesnerieae along with the genera Bellonia, Pheidonocarpa, and Rhytidophyllum. Gesneria species are usually woody shrubs or subshrubs, and (with the closely related Rhytidophyllum) are unusual in the family in having alternately (rather than decussately) arranged leaves. A complete list of the accepted species and their synonyms can be found in the Smithsonian Institution's World Checklist of Gesneriaceae.

Melianthus is a genus of flowering plants native to elevated grassland in South Africa, Lesotho, and Namibia. A common name for these plants is honey flower, which is also the English translation of the Latin name. This name also attaches to the species M. comosus and M. major that are found in cultivation.

Trichomanes is a genus of ferns in the family Hymenophyllaceae, termed bristle ferns. The circumscription of the genus is disputed. All ferns in the genus are filmy ferns, with leaf tissue typically 2 cells thick. This thinness generally necessitates a permanently humid habitat, and makes the fronds somewhat translucent. Because of this membrane-like frond tissue, the plant is prone to drying out. "Filmy ferns" in the taxa Hymenophyllaceae grow in constantly wet environments. Many are found in cloud forests such as "Choco" in Colombia. There are also members of the taxa that can grow submersed

Dirca is a genus of three or four species of shrubby flowering plants in the family Thymelaeaceae, native to North America. The genus is named after Dirce in Greek mythology. The general common name for this deciduous shrub is leatherwood; other names include moosewood, ropebark and the Powhatan-derived name wicopy, referring to its use as a fiber, wigub in the Algonquin languages. The stems of Dirca are exceptionally pliable and the bark is difficult to tear by hand; for this reason, its stems were used by Native Americans in eastern North America as thongs or ropes. The inner bark has cross-
