Amischotolype is a genus of perennial monocotyledonous flowering plants in the Commelinaceae. It is found in Central Africa and from India through Southeast Asia to New Guinea,Kew World Checklist of Selected Plant Families with the great majority or species found in Asia.Duistermaat, H. (2012). A taxonomic revision of Amischotolype (Commelinaceae) in Asia. Gardens' Bulletin Singapore 64: 51-131.
The name is derived from the Ancient Greek words αμισχος, meaning 'unstalked', and τολυπη, meaning 'tangle'. The genus is characterised by its rather compact inflorescences which are composed on two or more cincinni that pierce through the base of the leaf sheath, and also by its seeds that are embedded in red arils. Flowers are 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. The genus Porandra, which consists of three Asian species, is considered by Robert Faden, a leading authority on the family, to be "doubtfully distinct" from Amischotolype, and Plants of the World Online considers it a synonym. Analysis of DNA sequences has shown that Amischotolype is most closely related to the genus Coleotrype, while these two are in turn most closely related to the genus Cyanotis plus its synonym 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.
