To the H. Atrorubens this plant bears a strong affinity. It is larger 

 however, and its leaves instead of tapering to the base with a sHght acumi- 

 natum, abruptly terminate on hispid petioles two to three inches long; they 

 are broader also, much more rough, particularly on the under surface, and 



toothed
