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.
