Cassia javanica
Taxonomy
Cassia javanica is a very polymorphous species with a wide distribution range from N India through the Indochinese Peninsula and the Malesian region to New Guinea. We agree with Irwin & Barneby (l.c.) that Cassia pubiflora and C. microcalyx belong here. Cassia agnes, C. nodosa, C. renigera, and C. bartonii are also better treated as subspecies; the last two taxa show a certain degree of similarity even if they represent the most westernly and easternly variation of Cassia javanica.
We have treated the variation throughout on subspecific instead of varietal level in order to bring the present treatment as close as possible in conformity with the previous treatments in the Flora of Cambodia, Laos & Vietnam and that of Thailand.
