2016; Wen et al., 2016), and comparison to specimens of Primulina in herbaria (e.g. 
IBK, IBSC, KUN, PE), we have confirmed that it is indeed a new species of Primulina 
that is here described and illustrated. A provisional IUCN conservation assessment 
following the guidelines in IUCN Standards and Petitions Subcommittee (2016) is 
also provided. 
Taxonomy 
Primulina wuae F.Wen & L.F.Fu sp. nov. 
This new taxon is morphologically similar to Primulinapseudoroseoalba Jian Fi et al., 
P. roseoalba (W.T.Wang) Mich.Moller & A. Weber, P. subrhomboidea (W.T.Wang) Yin 
Z.Wang and P. beiliuensis B.Pan & S.X.Huang var .fimbribracteata F.Wen & B.D.Fai, 
but differs from these in the following characters (taxa listed in same order in each 
comparison to avoid repetition): bract size (2.1-2.5 x 0.85-1.1 cm in P. wuae vs 1.5-2 
x 0.8-1.2 cm in P pseudoroseoalba, vs 1.1-1.3 x 0.25-0.3 cm in P. roseoalba, vs 
0.4-0.6 x 0.2-0.3 cm in P. subrhomboidea, and vs 2.8^- x 2.5-3 cm in P. beiliuensis 
vwc. fimbribracteata)', bract indumentum (outside sparsely erect pubescent and densely 
puberulent, inside puberulent vs outside densely puberulent, inside glabrous, vs outside 
strigose, inside glabrous, vs outside puberulent and pilose, inside glabrous, and vs 
outside sparsely purple-pubescent, inside glabrous); pedicel indumentum (pubescent 
vs puberulent and glandular puberulent, vs puberulent and glandular puberulent, vs 
densely pubescent and pilose, and vs densely glandular-pubescent); anther indumentum 
(glabrous vs bearded, vs sparsely puberulent, vs villous, and vs densely white lanate), 
and pistil length (3-3.5 cm long vs 2.2-2.5 cm long, vs c. 2.8 cm long, vs c. 3.3 cm 
long, and vs 8^1 cm long). - TYPE: China, Guangxi Zhuangzu Autonomous Region,
