 liar among Ferns in having small fibrous annual roots; from hotii the latter the 

 present species is distinguished hy its larger more compound and finely cut fronds, 

 with dichotomously branched sori.

 none, root small tufted filjrous annual (?),stipites tufted very 

 slender filiform 2-4 inches high, fronds 2-3 inches long tri- 

 angulari-ovate membranaceous glabrous bipinnate, pinnules 

 ovate or subobovate cuneate at the base so as to form broad 

 wings on the rachis deeply pinnatifid, segments oblong very 

 obtuse entire or bifid, veins dichotomous, sori oblong simple 

 on the ultimate branches of the veins of each segment. —
