globoso-trilobus, basi calyce circumscisso cinctus, trilocu- 

 laris, (demuin tricoccus?) trispermus. Semina atra, ni- 

 tida, erecta, ovali-oblonga. 



This is very distinct from every species of Colletia hitherto 

 described, in the small very numerous dark-green spines, 

 and in the fascicles of flowers being collected so abundantly 

 about the extremities of the branches, as to form an ap- 

 parently dense raceme or spike, in the very elongated calyx, 

 of a reddish colour, and in the stamens being inserted a con- 

 siderable way down within the tube.

The whole structure of this plant, save the distinguishing 

 marks above given in the generic character, is so similar to 

 that of Colletia spinosa, that a description is scarcely neces- 

 sary. To this genus must unquestionably be referred the 

 Colletia pubescens * of Brongniart, of which I have given a 

 figure of the flower at Tab. XLV. A.
