03FEE8525419FFF580EAF8A57AF6FC4D.taxon	diagnosis	Distinguishing characters: — Primulina guigangensis is most similar to P. yungfuensis. Shared characters mainly include leaf with similar shape and indumentum, cyme 2 – 6 - flowered with two bracts. However, P. guigangensis can be distinguished by its 8 – 15 cm long peduncle (vs. 4.5 – 9.0 cm long), calyx apex acuminate (vs. acute), corolla 2.8 – 3.5 cm long (vs. 3.8 – 4.6 cm long), tube narrowly funnelform, 1.8 – 2.5 cm long, inflated above the mouth (vs. tube tubular, 2.5 – 3.0 cm long, not inflated), filaments densely glandular puberulent (vs. glabrous), stigma long elliptic (vs. linear) and flowering in September – November (instead of March).	en	Wu, Lei, Zhang, Qiang, Xu, Wei-Bin, Mo, Shui-Song (2012): Primulina guigangensis (Gesneriaceae): a new species from limestone area in Guangxi, China.
