In the Paris herbarium, there is a singular plant received. 
from Para, which forms so distinct a genus of the tribe 
Cassiee, connecting it on the one hand with Swartzie 
through Martiusia, of which it has in some measure the

shortened calycine tube, that I subjoin the generic character 
with a short description. -
