Primulina anisocymosa (Gesneriaceae), a new species with a unique inflorescence structure from Guangdong, China

A new Primulina species from Guangdong, China with an unusual inflorescence is described here. Primulina anisocymosa is vegetatively most similar to P. bobaiensis. It can be distinguished from all species within Primulina morphologically by its unique zigzag monochasial cyme and infructescence. To c...
