The author and typification of Tradescantia zebrina (Commelinaceae)

摘要

Tradescantia zebrina Heynh. ex Bosse is found to be the correct citation for this common plant, although the older name Tradescantia zebrina Heynh. has been used for it in some recent publications and on-line databases. The Heynhold citation lacks a description and therefore it is an invalid name. Tradescantia zebrina is neotypified by a modern collection from Mexico.
