Primulina rufipes Y.L. Su, P. Yang & Yan Liu (Gesneriaceae), a new species from Guangxi, China, is described and illustrated. Molecular phylogenetic analyses unambiguously put this species in Primulina. Morphological observations and comparisons showed that P. rufipes is similar to P. huaijiensis Z.L. Ning & J. Wang, differing by all over the plant densely pubescent and glandular-puberulent, leaf blade elliptic to rhomboid-ovate, and obliquely campanulate corolla without appendages. P. rufipes is also similar to P. yulinensis Ying Qin & Yan Liu and P. gongchengensis Y.S. Huang & Yan Liu in vegetative characters, but its obliquely campanulate corolla is obviously different from the latter two species.
Carex pingleensis Z.C. Lu, Y.F. Lu & X.F. Jin, anew species of Carex sect. Mitratae Kuk. from northeastern Guangxi, China, is described and illustrated. This species is easily distinguished from all the other species of sect. Mitratae by its spikes gathering at the top of culms; nutlets neither contracted on angles nor excavated at faces; male glumes apex obtuse, both sides united near base, abaxial surface with pubescence and utricles shorter, only 2.8-3.2 mm long, densely pubescent.
