Abstract
A new species, Fordiophytontereticaule, from China, is described and illustrated here based on morphological and molecular evidence. It is morphologically similar to F.faberi in having erect stems, slightly oblique and membranous leaf blades, broadly ovate to suborbicular bracts, and oblong petals, but differs by the terete stems, densely puberulous petioles, and elliptic leaf blades. Our phylogenetic analyses based on plastid genome and nrITS data indicate that this new species is clustered with four Fordiophyton species of Yunnan but placed far apart from F.faberi. An updated key to the genus is also provided.
