Cassia javanica subsp. microcalyx

Primary tabs

Cassia javanica subsp. microcalyx


Deviates in having linear-acute stipules like in subsp. pubiflora, combined with a tiny calyx of sepals 4-5.5 mm long, petals 15-20 mm long.


Asia-Tropical: Borneo present; Sumatera (Sumatera present)
Malesia: Sumatra and Borneo.


Irwin & Barneby (l.c.) suggest that their var. microcalyx appears to replace other forms of Cassia javanica in Sumatra and Borneo; this has to be investigated more closely.
