Since The coming week will have maximum upload of species from Cassia
complex now divided into three genera, here is simple key to separate them
1a. The longest filament (or filaments of three anterior stamens)
sigmoidally
curved, longest more than 2.5 cm long
................................................ 1. Cassia
1b. The longest filament straight, less than1 cm
long.................................... 2
2a. Ovary stalk more than 0.9 mm long, fruit more than 9 cm long;
bracteoles absent; legume not elastically coiling
.....................................2. Senna
2b. Ovary stalk less than 0.9 mm long, fruitless than 9 cm long; braceoles
present; legume elastically
coiling......................................................... 3.
Chamaecrista
