Systematics & Distributions

Plowmanianthus is a member of the subtribe Dichorisandrinae of the tribe Tradescantieae of the flowering plant family Commelinaceae. It has 5 species and 2 subspecies, all of which were described with the circumscription of the genus itself by Hardy and Faden (2004). Proceeding from the north to south and southeast of the genus's distribution, the taxa are as follows.

Taxonomy

The genus name of Plowmania is in honour of Timothy Plowman (1944–1989), an American ethnobotanist best known for his intensive work over the course of 15 years on the genus Erythroxylum , and the cultivated coca species in particular. [2] It was first described and published in Syst. Bot. Vol.29 on page 316 in 2004. [1]

Morphology

Rosette, typically unbranched herbs with somewhat succulent, strap-shaped leaves. In the wild, plants grow on the floor of primary rainforests, shallowly rooted in the humus-rich and leaf-litter layers.

Plowmanianthus resembles its close relative, the epiphytic genus Cochliostema , but is smaller (its leaves reach only to ca. 30 cm in length) and is not epiphytic. Its flowers are also much smaller, lack the spirally coiled anthers of Cochliostema, and are usually cleistogamous (i.e., they usually never open).

<i>Stanhopea</i> Genus of orchids

Stanhopea is a genus of the orchid family (Orchidaceae) from Central and South America. The abbreviation used in horticultural trade is Stan. The genus is named for the 4th Earl of Stanhope (1781-1855), president of the Medico-Botanical Society of London (1829-1837). It comprises 55 species and 5 natural hybrids. These epiphytic, but occasionally terrestrial orchids can be found in damp forests from Mexico to Trinidad to NW Argentina. Their ovate pseudobulbs carry from the top one long, plicate, elliptic leaf.

<i>Brassia</i> Genus of orchids

Brassia is a genus of orchids classified in the subtribe Oncidiinae. It is native to Mexico, Central America, the West Indies, and northern South America, with one species extending into Florida.

<i>Stenia</i> Genus of orchids

Stenia is a genus in the orchid family (Orchidaceae). It was established by John Lindley in 1837. These epiphytic plants occur in warm, humid habitats of Trinidad and the Amazonian slope of the northern Andean region in South America.

<i>Dichorisandra</i> Genus of flowering plants

Dichorisandra is a genus of perennial monocotyledonous flowering plants in the dayflower family (Commelinaceae). It is found in the Neotropics. The genus is characterised by its slightly zygomorphic flowers with large anthers usually releasing pollen by means of pores at the apex, as well as by its seeds that are embedded in a red or sometimes white aril, and tubers that often form at the tips of the roots. Both morphology and an analysis of DNA sequences indicate it is very closely related to the genus Siderasis.

Cochliostema is a genus of plants with two species in the family Commelinaceae. The genus occurs from southern Nicaragua to southern Ecuador.

<i>Lepechinia</i> Genus of flowering plants

Lepechinia is a genus of plants in the mint family, Lamiaceae. It includes several species of plants known commonly as pitchersages. Plants of this genus can be found in Central and South America, Mexico, California, Hispaniola, and Hawaii, although the species in Hawaii is probably a human introduction. Many of them bear attractive pitcher-shaped flowers, often in shades of purple. The genus was named for the Russian botanist Ivan Ivanovich Lepechin. Recently, the two monotypic genera Chaunostoma and Neoeplingia were shown to be part of Lepechinia.

Geogenanthus undatus is an outdated synonym for G. poeppigii. For more details on the rather complicated synonym for this species, see Faden (1981).

Timothy Charles Plowman was an ethnobotanist best known for his intensive work over the course of 15 years on the genus Erythroxylum in general, and the cultivated coca species in particular. He collected more than 700 specimens from South America, housed in the collection of the Field Museum of Natural History. The standard author abbreviation Plowman is used to indicate this person as the author when citing a botanical name.

<i>Evodianthus</i> Genus of flowering plants
