~ LABOUCHERIA, n. g. MIMOSEARUM. 
Flores hermapbroditi regulares. Calyx infundibulari-campanulatus

* The specimens are not sufficient to make out the estivation of the corolla 
satisfactorily ; but it appears to me, that one of the lower petals is the external 
one: the habit and other characters in the flower are those of Cesalpinea, of 
the subtribe Cynometree; whilst the incurved radicle would place it in the 
Sophorea, where I know of no génus at all allied to it.—G. B.
