摘 要

基于形态学证据，本文描述了报春苣苔属（苦苣苔科）一新种——粗筒小花苣苔Primulina inflataLi.H. Yang & M.Z. Xu。新种在叶片形状和毛被上与休宁小花苣苔P.xiuningensis(X.L. Liu & X.H. Guo) Mich. Möller & A. Weber相似，但与后者不同的是其花冠上有紫红色纵条纹（vs.后者花冠黄色无条纹）、花冠筒呈膨大的管状（vs. 管状）和直的花丝（vs. 膝状弯曲）。本文还提供了新种的描述，手绘图和彩色照片。

Based on morphological observations and comparisons, a new species of Primulina(Gesneriaceae), P. inflataLi.H. Yang & M.Z. Xu, is described and illustrated. This new species resemblesP. xiuningensisin leaf blade shape and indumentum, and differs from the latter by the white corolla with longitudinally purple-red stripes (vs. yellowish without stripes), inflated tubular corolla tube (vs. tubular) and straight filament (vs. geniculate). The descriptions, illustrations and photographs of this new species are provided here.
