serrate or pinnatifid. — II. F. 35. — a. A . rhreticum (Eoth) ; 
frond bipinnate, pinnules toothed narrowly triangular- 
lanceolate convex remote not connected toothed, upper ones 
minute confluent, clusters ultimately confluent. N. 245. A.

enclosing the clusters : their attachment broad ; segments 
gradually decreasing from the base of pinnule. — /3. A. Fiiix-
