Primulina pseudoroseoalba (Gesneriaceae), a New Species from a Karst Cave in Guangxi, China

Primulina pseudoroseoalba Jian Li, F. Wen & L.J. Yan, a new species of Gesneriaceae from China, is described and illustrated. It is morphologically similar to P. roseoalba, but differs from it in the leaf blade being broadly ovate to elliptic, and its margin entire and abaxially glabrous; peduncle being much shorter; and bracts being ovate to orbicular-ovate, glabrous inside. Primulina pseudoroseoalba is rare and currently known only from a karst hill in Guangxi, China.
