Two jasmine (Oleaceae: Jasminum L.) taxa newly recorded in Vietnam

Two Jasminum taxa i.e. J. hongshuihoense and Jasminum laurifolium var. brachylobum are reported as a new record for the flora of Vietnam. J. hongshuihoense was hitherto known as endemic to China. It differs from the closely related species J. eberhardtii in having more number (4-10) of primary veins and lesser (5-8) calyx lobes. J. laurifolium var. brachylobum is closely allied to J. laurifolium var. laurifolium but it differs in having more flowers in cymes (i.e.1-8) flowers and calyx lobes (i.e. 6-10). Description and color photographs are provided for species identification. Furthermore, a comparison of the diagnostic characters with those of related species is made.
