Frond 7-8 inches long, divided nearly to the base into 
several segments, which vary from 3 an inch to an inch in 
breadth, taper to the base, are broader upwards and are either 
forked or twice or thrice dichotomous, with widely spreading 
angles. The margin is simple, or sparingly proliferous. 
Over the surface of the lacinie, on one or both sides of the 
frond, papillæform bodies, containing granules, but not ex-
