often pinnatifid. Veins simple, or forking at very acute angles, subpinnate 
in the pinnatifid segment. Sori short, '/z—1‘, one at the base of a seg- 
ment, close to the midrib of the pinnule; the first ones generally curved 
or horseshoe- a Invol. firm, vaulted, pSouewa entire or denticulate.

Common on all sands from 1000—6000 ft. upward. One of my numerous specimen 
is bipinnate. In another the ultimate segments se! ahr appear almost saa: 
but in the plants from the higher regions the same are shorter and more obtuse, while 
their pinnules contract, thus imparting an open matter rance to the frond. 
B var. — Quadripinnate. Rhachis darker, compressed, flaccid. Pinnae 
and pinnules narrower. Ultimate pinnules with several veins and shorter 
rather obtuse segments. Sori at the base of the ultimate pinnules, or near 
their middle when pinnately cut.
