XXXII. OCHXACEiE. 



This Family, although not numerous, is remarkable for the 

 elegance of its habit, the peculiar lustre of its foliage and the 

 brilliancy of its flowers and fruits, as well as by the large number 

 of some of its species, which in certain hilly districts, in conjunc- 

 tion with species of DicJiajJetalum, Rubiacepe, and Filices, constitute 

 the underwood of the forests. See Welwitsch, Apont. p. 565, n. 157.
