De. Matin: This Fern 
The dark color of the stalk and rachis extends along the midribs of the pinne for about half their length. 
The frond is nearly, if not quite, glabrous, and of a clear, bright-green color. 
Cheilanthes viscida, Davenport, (n. sp.). 
Stalks 3-5 inches high, wiry, blackish, shining, the base chaffy with 
narrow crisped bright-ferruginous scales ; frond herbaceous, minutely gland- 
ular and everywhere viscid, 3-5 inches long, narrowly oblong in outline, 
pinnate with 4-6 distant pairs of nearly sessile deltoid bipinnatifid pinne 
5-6 lines wide and long; segments toothed; the minute herbaceous teeth 
recurved, and each covering 1-3 sporangia. 
Collected in 1876 by Dr. Parry, probably near San Bernardino, California. This slender Fern much 
resembles C. Wrightii, but has the fronds taller, more finely divided, and excessively viscid, and tho 
involucre is represented only by the recurved teeth of the segments. Indeed, it might almost as properly 
be considered a Notholena, but its apparent affinities are with Cheilanthes Sosce ret Pra x 
received specimens from Mr. Geo. E. Davenport, of Boston, with the MS. name here adop 
Cheilanthes microphylla, Swartz. 
Rootstock creeping, short; stalks clustered, dark-brown, glossy, but 
rusty-pubescent along the upper side, 4-6 inches long; frond as long as the 
stalks, ovate-lanceolate in outline, twice or even thrice pinnate; primary 
pinne numerous, lanceolate, the lowest ones usually largest and more del- 
toid; secondary ones oblong or deltoid-ovate, deeply incised, or again pin- 
nate in large specimens ; texture rather firm ; both surfaces smooth or with 
a very scanty pubescence ; involucres nearly unchanged from the texture 
of the frond, interrupted or subcontinuous.—Synopsis Filicum, p. 127;

has a frond unusually broad at the base, — thrice pinnate, and comes nearer to the var. Moritzia

Cheilanthes Alabamensis, Kunze. 
Rootstock “creeping,” clothed with very slender delicate bright- 
brown scales, which at the base of the polished black stalks pass into a 
scanty ferruginous wool; frond narrowly lanceolate, 2-8 inches long,
