Fallopia is a genus of about 12–15 species of flowering plants in the buckwheat family, often included in a wider treatment of the related genus "Polygonum" in the past.
 The genus is native to temperate and subtropical regions of the Northern Hemisphere.
 The genus includes herbaceous perennial plants, herbaceous vines, and woody vines.
Cleyera is a plant genus consisting of 18 species of tender, evergreen shrubs to small trees, mostly native to Mexico and Central America, and one from Eastern Asia.
 In the APG III system it is placed in the family Pentaphylacaceae.
Dipsacus is a genus of flowering plant in the family Caprifoliaceae.
 The members of this genus are known as teasel, teazel or teazle.
 The genus includes about 15 species of tall herbaceous biennial plants (rarely short-lived perennial plants) growing to 1 - tall.
 Dipsacus are native to Europe, Asia and northern Africa.
Flemingia is a genus of flowering plants in the legume family Fabaceae.
 It is native to Asia and the species are distributed in Bhutan, Burma, China, India; Indonesia, Laos, Malaysia, Nepal, Pakistan, Papua New Guinea, Philippines, Sri Lanka, Taiwan, Thailand and Vietnam.
 The genus was founded in 1812.
 The number of known species is ambiguous due to taxonomic problems; and is usually enumerated as more than 30.
 Burma and China have the highest record of "Flemingia" species with 16 each, followed by India (with 15 species), Thailand (11 species), Laos (10 species), Vietnam (8 species), Bhutan (1 species) and Nepal (5 species).
Mastacembelus is a genus of many species of spiny eel fish from the family Mastacembelidae.
 They are native to Africa (c. 45 species) and Asia (c. 15 species).
 Most are found in rivers and associated systems, but there are also species in other freshwater habitats and a particularly rich radiation is found in the Lake Tanganyika basin with 15 species (14 endemic).
Abelia is a genus of about 30 species and many hybrids in the honeysuckle family Caprifoliaceae.
 Some authors, including the Angiosperm Phylogeny Group, consider "Abelia" and related genera to belong instead in the segregate family Linnaeaceae, also including such genera as "Linnaea", "Abelia", "Dipelta", "Kolkwitzia", and "Zabelia", but not such others as "Lonicera" or "Symphoricarpos," included by them instead in a more narrowly viewed Caprifoliaceae.
Polycarpon is a genus of flowering plants in the pink family.
 They are known generally as manyseeds.
 There are roughly 9 to 15 species, representing most continents.
 The best-known species is perhaps "Polycarpon tetraphyllum", which is native to southern Europe but is present in many other regions as an introduced species.
 These plants are low, matted annuals spreading slender stems along the ground or erect with many branches.
Nertera is a genus of about 15 species of flowering plants in the family Rubiaceae, native to the Southern Hemisphere, in South America and Australasia, with one species extending into the Northern Hemisphere in Central America, eastern Asia, and Hawaii.
 The name derives from the Greek word "nerteros", meaning low down.
 Common names include pincushion, coral bead or bead plant.
 They are prostrate, creeping, mat-forming herbaceous perennial plants growing to 20 - across or more but no more than a few centimetres high.
 The leaves are usually quite small, and when crushed may in some species release a foul smell (methanethiol) like the related woody genus "Coprosma".
 The flowers are insignificant and probably wind-pollinated.
 The fruit is usually a bright orange berry, but in some species may be a dry capsule.
Pectocarya is a plant genus of about 15 species in the family Boraginaceae.
 Plants in this genus are known generally as combseeds.
 They are small annual plants which bear tiny white flowers no more than 3 millimeters in diameter.
 Their fruits are nutlets which often have small projections that look like the teeth of a comb, hence their common name.
 The nutlets usually come in clusters of four.
 These plants are found mainly in western North America.
Richardia (Mexican-clover) is a small genus of about 15 species of flowering plants in the family Rubiaceae, native to tropical to warm temperate regions of the Americas, with one species also native to Fiji in the Pacific Ocean.
 They are mostly annual plants, a few species being herbaceous perennial plants.
