Coleotrype is a genus of perennial monocotyledonous flowering plants in the dayflower family. It is found in Africa and Madagascar. [1]

The genus is characterised by its extremely contracted inflorescences with each unit being subtended by a relatively large bract, and the petals that form a short tube at the base in which the stamens are attached to it. Flowers may be either zygomorphic or actinomorphic, and anthers release their pollen either through a pore at the tip or slits down the sides. They are typically encountered in forest understories. [2] [3]

Analysis of DNA sequences has shown that Coleotrype is most closely related to the genus Amischotolype , while these two are in turn most closely related to the genus Cyanotis plus its very close relative Belosynapsis . These four genera form a clade that is found only in the Old World, while all of its immediate ancestors are present only in the New World. [4]

<span class="mw-page-title-main">Commelinaceae</span> Family of flowering plants

Commelinaceae is a family of flowering plants. In less formal contexts, the group is referred to as the dayflower family or spiderwort family. It is one of five families in the order Commelinales and by far the largest of these with about 731 known species in 41 genera. Well known genera include Commelina (dayflowers) and Tradescantia (spiderworts). The family is diverse in both the Old World tropics and the New World tropics, with some genera present in both. The variation in morphology, especially that of the flower and inflorescence, is considered to be exceptionally high amongst the angiosperms.

<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.

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

Cyanotis is a genus of mainly perennial plants in the family Commelinaceae, first described in 1825. Species of the genus are native to Africa, southern Asia, and northern Australia.

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

Aneilema is a genus of monocotyledonous plants of approximately 60 species. The vast majority of the species are native to sub-Saharan Africa, but a few are found in Oceania and one, Aneilema brasiliense, is from South America. It is the third largest genus in the family Commelinaceae after Commelina and Tradescantia, and it is one of only six genera in the family to occur in both the Eastern Hemisphere and the Western Hemisphere.

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

Palisota is a genus of plant in family Commelinaceae, first described in 1828. It is native to sub-Saharan Africa.

<span class="mw-page-title-main">Commelinoideae</span> Subfamily of flowering plants

Commelinoideae is a subfamily of monocotyledonous plants in the dayflower family (Commelinaceae). It is one of two subfamilies within the Commelinaceae and includes 39 genera and all but 12 of the family's several hundred known species. The subfamily is further broken down into two tribes, the Tradescantieae, which includes 26 genera and about 300 species, and the Commelineae, which contains 13 genera and about 350 species.

<i>Geogenanthus poeppigii</i> Species of flowering plant

Geogenanthus poeppigii, commonly called the seersucker plant, is a flowering plant species in the family Commelinaceae. As currently circumscribed, the genus Geogenanthus includes two other species, G. ciliatus and G. rhizanthus. This species is named after 19th century German naturalist Eduard Friedrich Poeppig. Geogenanthus undatus is an outdated synonym for G. poeppigii.

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

Cartonema is a genus of perennial or annual monocotyledonous flowering plants in the dayflower family. It is restricted to Australia and nearby Trangan Island, which is part of Indonesia. It is the earliest diverging member of its family and has a number of traits that are unique within it, such as non-succulent leaves and a lack of raphides. Its distinctive features led to the genus to once be considered part of its own separate family, Cartonemataceae. However, analysis of DNA sequences, as well as many common anatomical characters, has supported its relationship with the Commelinaceae. It contains about 11 species.

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

Triceratella is a genus of annual monocotyledonous flowering plants in the dayflower family. The genus consists of a single species, Triceratella drummondii. It is known to occur in Zimbabwe and Mozambique, but has only been collected twice. Because of its rarity, DNA sequences have never been used to determine its relatives, but it is believed to be closely related to the early diverging genus Cartonema, with which it shares a number of characters unique for the dayflower family, such as a yellow flowers, glandular hairs, and a lack of glandular microhairs. It differs from Cartonema, however, in having raphides, which all other members of the Commelinaceae have, although they occur in a unique position next to the leaf veins in Triceratella.

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

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

<span class="mw-page-title-main">Commelineae</span> Tribe of flowering plants

Commelineae is a tribe of monocotyledonous flowering plants in the dayflower family (Commelinaceae). The tribe consists of 13 genera and about 350 species. It is one of two tribes in the subfamily Commelinoideae, the other being the Tradescantieae, which is made up of 26 genera and about 300 species. The remaining two genera in the family are in a separate subfamily, the Cartonematoideae.

<i>Pollia</i> (plant) Genus of plants

Pollia is a genus of flowering plants in the family Commelinaceae, first described in 1781. It is widespread through the Old World Tropics: Africa, southern Asia, northern Australia, etc. There is also one species endemic to Panama.

Pseudoparis is a genus of perennial monocotyledonous flowering plants in the family Commelinaceae, first described in 1936. The genus contains three known species, all endemic to Madagascar.

<i>Commelina africana</i> Species of flowering plant

Commelina africana, the common yellow commelina, is a widespread species of flowering plant in the family Commelinaceae. It is native to Sub‑Saharan Africa, Madagascar, Réunion, and the Arabian Peninsula, and has been introduced to India. It is occasionally consumed as a leaf vegetable, and occasionally fed to rabbits and pigs.
