 rado, 3 November, 1904, Brandegee. — This species, though somewhat 

 variable in the breadth and toothing of the leaves, seems to be constant 

 and readily recognizable as to essentials. It is readily distinguished 

 from B. Wislizeni by its smaller decidedly fewer- flowered heads, 

 looser inflorescence, and larger leaves.
