 viscidly pubescent calix and peduncle, with ihe numer- 

 ous flov.-ers, and the approximating equality of the leaves, 

 distinguish this species readily from the preceding; the 

 hemispherical calix and numerous rays (more thaii 20), 

 like vise separate it from the following. ^. * bcUidifoUus .
