but the latter (known to the writer only from Progel's description in 

 the Flora Brasiliensis, vi. pt. 1, 274) is said to have coriaceous leaves 

 about three times as long as broad, and a corolla which is granulose- 

 pulverulent on the outside. Furthermore, the figure of the corolla 

 (Progel, 1. c, t. 82, f. II.) shows the bearding only at the throat, while 

 in the species here characterized it extends well out upon the lobes.
