Group members in Guilin Botanical Gardens have found two new species of Gesneriaceae when they surveyed the limestone area.

These two are Primulina zhoui and P. huangii. Primulina zhoui is similar to P. multifida B. Pan & K.F. Chung, but differs from the latter 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.
