276 PHANEROGAMIA. 



eels solitary or geminate, 3 lines long. Drupe oblong, fully 3 lines in 

 length, with a thin, dry pulp, and a bony, one-celled putamen. 



This is without doubt a congener of GondaUa microphylla, with 

 which it accords in habit. But its leaves are much thicker, and con- 

 spicuously lineate underneath with parallel and approximate nerve- 

 like veins ; and the fruit is of a different shape. 



4. COLLETIA, Oommers. 



1. Colletia spinosa, Lam. 



Hab. Chili. Lagunas and Valparaiso : a form with short and ex-

 softly puberulent.
