Validation of the Name Pararuellia alata (Acanthaceae)

摘要

During preparation of a treatment of Acanthaceae for the Flora of China, it was determined that Pararuellia alata H. P. Tsui from Yunnan, China, was not validly published because the herbarium in which the type is conserved was not specified. The name is herein validated with the herbarium now specified. The species can be distinguished from other Chinese Pararuellia Bremekamp by its winged inflorescence rachis.
