According to W. T. Wang et al., 1998 [9], the genus Loxostigma C. B. Clarke had about 7 species mainly distributed Asia. There were 4 Loxostigma species in Vietnam. This paper reported a new record of Loxostigma fimbrisepalum K. Y. Pan for the flora of Vietnam.
Loxostigma fimbrisepalum is herbs, stems 50-100 cm, sparsely puberulent, or near glabrescen. Leaves opposite, spread along stem; leaf blade ovate to broadly elliptic, 8-20  3.0-8 cm, apex acuminate, sparsely puberulent on both of surfaces. Cymes branched 2-5, 5-18-flowered; peduncle 5-20 cm; bracts ovate to broadly ovate. Pedicel 1-2 cm.
