Combretum. OCTANDRIA MONOGYNIA. 225 
Observation. 
This plant appears to me to be nearly allied to Osbec- 
kia, however the want of the intermediate small scales of 
the calyx, and their being only four stamens, are I think 
sufficient motives for doubt. Compare with Melastoma, 
also with Rhexia. 
New genus (Blank.) 
Calyx entire. Corvol four-petalled, insertod on the 
calyx. Capsule inferior, four-celled; receptacles parie- 
tal. Seeds numerous.

pointed, three-nerved, smooth on both sides. Corymbs 
terminal, and axillary, much shorter than the leaves,

tes minute. Calyx entire. Petals four, contorted, ovate- 
cordate, subsessile, expanding, inserted in the mouth of

fine. Anthers crescent-shaped, with a double pollenifer- 
0us groove on the inside, Germ inferior, roundish, small.
