Taiwania 63(1):54-60.

                                                                         摘要

    报道和描述了发现于中国广西石灰岩地区的苦苣苔科植物二新种——周氏小花苣苔和黄氏小花苣苔。周氏小花苣苔与多裂小花苣苔相似,但从其苞片、花萼萼片、花冠、花冠唇和花盘上的特征能够很好地与后者区别;黄氏小花苣苔近于羽裂小花苣苔,但其苞片、花梗、花冠、花冠筒、花冠唇和雌蕊的特征均可与后者区别。上述详见全文。

    Primulina zhouiand P. huangii, two new species of Gesneriaceae from the limestone area in Guangxi,China are described and illustrated. Primulina zhouiis similar toP. multifidaB. Pan & K.F. Chung, but differs from the latter in its bracts, calyx lobes, corolla, adaxial lip and disc. Primulina huangiiclosely 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.
