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]
