Taiwania 63（1）：54-60.

ABSTRACT

Primulina zhoui and P. huangii, two new species of Gesneriaceae from the limestone area in Guangxi,China are described and illustrated. Primulina zhouiis similar to P. multifida B. Pan & K.F. Chung, but differs from thelatter in its bracts, calyx lobes, corolla, adaxial lip and disc. Primulina huangii closely resembles P. bipinnatifida (W.T.Wang) Y.Z. Wang & J.M. Li, but differs from the latter in its bracts, pedicel, corolla, corolla tube, adaxial lip and pistil. Above-mentioned details are showed in the article.
