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.

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.
