Taiwania 65(2): 163-166, 2020

ABSTRACT

        Based on morphological observations and comparisons, a new species of Primulina (Gesneriaceae), P. inflata Li.H. Yang & M.Z. Xu, is described and illustrated. This new species resembles P. xiuningensis in 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.
