A REVISION OF THE INDO-CHINESE-MALAYSIAN GENUS STROPHIOBLACHIA (EUPHORBIACEAE)

The genus Strophioblachia Boerl. is very variable, but does not show a ny gaps in characters, which can be used for a further delimitation of taxa. This is shown for characters like habit, leaf blade shape, leaf blade base, staminate petals and disc lobes, bracts, and the fimbriae of the pistillate calyx. The characters show their differences on the same specimen (e.g., leaf shape), within the same area (e.g., size an d number of staminate petals), or in different areas of the distributi on range (e.g., efimbriate pistillate calices in China, Thailand, and Sulawesi). Therefore, the formerly recognized species and varieties ar e united into a single accepted species, S. fimbricalyx.
