Notes
S. braeteolata appears to be pollinated by thrips (Appanah) whereas S. roxburghii has been found to be visited by bees in Thailand (Smitinand, pers. comm.). Most species are rather uniform and well defined, the notable exception being the widespread S. assamiea and its siblings S. agamii of Borneo, which has two subspecies, one of which can be triploid, and S. resinosa in which abundant apoximis through adventive polyembryony is well known (Foxworthy, Kaur).
