The figure which is here given of this species is from my 
Organ Mountain specimens. 1 have preferred Willdenow's 
Specific name of riparia to that of Capensis, since the species 
1$ now found to be common to Brazil and the Cape.

lanceolatis acuminatis pinnatifidis laciniis oblongis acutis 
obtuse serratis, soris ad medio venularum, rachibus alatis.
