ABSTRACT: Glycosmis longipetala F. J. Mou & D. X. Zhang is described from Guangxi and  Yunnan  provinces in southwestern  China . The new species is similar to G. cochinchinensis (Lour.)  Pierre  ex Engl. by its simple leaves, but distinguishable in having long-elliptic or oblanceolate (vs. ovate) leaves, long-ovoid to ellipsoid (vs. ovoid) floral buds, ovaries with many tubercles (vs. smooth) and glabrous (vs. pubescent) stamens. The pollen grains of the new species are 23.9 +/- 3.09 (20.8-27.0)x22.0 +/- 1.80 (20.4-24.4) mu m in size with reticulate exine ornamentation in equatorial area and foveolate in polar area. The chromosome number of the new species is 2n=72.
