 of the stipes above sparsely and rigidly beneath densely soft 

 cano-hirsute tripinnate, lower primary inferior pinnae ovate 

 acuminate, secondary ones petiolate oblong-lanceolate acumi-

 or most of them adnate and decurrent at the inferior base, seg-

 tween the costule and the margin, capsules lax." Metten. — Po-

 This Fein attains a considerable size. My specimens from Spruce precisely ac- 

 cord with authentic ones from Klotzsch and from Fendler. Of Spruce's speci- 

 mens, the stipes is at the base as thick as one's thumb, densely clothed with long 

 narrow crisped scales ; the entire stipes is 4-5 feet long ; the frond 4 feet long ; 

 tiie ultimate i)innrc (often slightly coadunate at the base) are I-} of an inch long, 

 crcnato-pinnatifid rather than pinnatifid. Still the species is not to me satisfac- 

 torily defined. 



203. P. (Phegopteris) connejmn, KUs. ; "stipes 1 foot long 

 paleaceo-pilose at length naked, frond membranaceous tender, 

 beneath on the costce and costules densely pu1)escenti-hirsute 

 1 ^-2 feet long oblong acuminate, at the base only or through- 

 out bipinnate, primary segments 8-9 inches long petiolate, 

 basal ones ovato -lanceolate, superior ones oblong-lanceolate 

 a(;unnnate, secondary ones 1-2 inches long oblong or elon- 

 gato-ol)long acuminate or obtuse deeply pinnatijiartite or 

 jiinnatifidly crenate, basal ones sessile, lateral ones dilated 

 below, superior ones adnate at length coadunate by the infe- 

 rior decurrent base, segments oblong obtuse, veins with pin- 

 nated undivided branches, the tertiary ones soriferous."

 they do not satisfy me that the species is a very distinct one.
