CLASSIFICATION OF ANGIOSPERMS. 601 



FIG. 331. Yerba Mate trees (Ilex paraguariensis) growing in Pereira Continho and 

 Almeido, Santos, Brazil. The plants are shrubs or small trees, with ovate or nearly spatu- 

 late, dentate and slightly coriaceous leaves. The latter are used, under the name of Para- 

 guay tea, in the preparation of a tea-like beverage. The trees are extensively cultivated 

 in South America, and large quantities of Mat6 are consumed annually. The young branches 

 are gathered between December and August, dried over a fire, the leaves being separated, 

 and are then ready for market. Reproduced by permission of The Philadelphia Com-
