Provinces of Goyaz and Minas Geraes, and, according to Edwall,* 
e a 
places where it occurs are Serra Azul, Cravintras, Sao Simao, 
raraquara, Casa Branca, Riberao Preto. While it is probable 
that as a wild plant it pira the well-marked dry period of its 
native campo, it can be grown in a more moist climate to a less 
luxuriant extent. Towards the west it spreads through Matto

crown, the breadth of which often considerably exceeds ee whole 
or long-elliptie pe, are contracted towards the rounded apex, 
2-4 in. long and j-1j in. broad. The leaf-stalks are short—as a 
rule but 4 in. long. nervation the leaf is well marked; it has 
a straight midrib from which on either side Spring numerous 
veins parallel to one another, and sometimes forked to support
