ciliated scales, soft and tomentose on the pinnules, but gradually 
more andmo're rigid towards the rootstock, where they are hard and 
nearly blacjc. 
46. Pellma marpnata, Baker. — Stalks tufted, slender, castaneous, 
shining ; fronds four to six inches long and nearly as broad, deltoid 
in outline, tri-quadri-pinnatifid, segments linear-oblong, chartaceous ; 
smooth ; involucre broad, continuous, delicate, the margin slightly 
arose. — Syn. Fib, p. 151. Cheilanthes margiiiata^ Hooker. 
Huachuca Mts., Arizona, Prof, and Mrs. Lemmon, August, 1882. 
Common in Tropical America from Mexico and the West Indies to 
Peru. It is often difficult to distinguish between this and P, angtisti- 
folia^ though the latter has commonly a less decompound frond, and 
longer and more distant ultimate segments. 
47. Cheilanthes Alabamensis^ Kunze, — Pluachuca Mts., Arizona, 
Prof, and Mrs. Lemmon, August, 1882. A more western station 
than any before reported. 
48. Cheilanthes lendigera^ Swartz. — Rootstock cord-like, creeping, 
covered with soft narrow scales ; stalks rather distant, 4-8 inches 
long, at first loosely tomentose with ferruginous hairs, at length 
castaneous and nearly smooth ; fronds as long as the stalks, ovate- 
oblong, thrice to four times pinnate, ultimate pinnules cuneate- 
obovate, less than a line long, the margin recurved and the white 
involucre leaving but a small opening in the middle, making the 
pinnules pouch-like; upper surface green and naked, the lower 
hairy. — Hooker, Sp. FiL, ii., p. 95, t. civ., B. 
Huachuca Mts.^ Prof, and Mrs. Lemmon. 
This is another well-known species of Mexico and the Andes of 
Colombia and Ecuador. It is much less woolly than C tomeniosa^ 
and the pouch-like ultimate pinnules are very noticeable. 
49. Asplenium montanu?n^ Willd. — This must now be considered 
a New England fern. One day last April three students of the 
Academy at Norwich, Conn., started out for a day's search for 
*'trailing-arbutus, lichens and rocks.* Messrs. Fuller and Setchel 
found this fern in clefts of rocks on Lantern Hill, which rises be- 
tween the towns of Ledyard and North Stonington. Mr. Fuller first 
saw the plant, Mr. Setchel identified it, and Mr. Collin has the 
honor of being one of the party. 
About Christmas, 1882, Mr. C* B. Graves, of New London, also 
discovered the plant on the same mountain, and also on a smaller 
hill distant a little way to the north-east. Mr. Graves says it is not 
uncommon in holes and crevices of the rock. It is to be hoped that 
the difficulty of getting to the place will long prevent the extirpation 
of the fern. 
50. Asplenium inonanthemum^ L., was found among Prof. Lem- 
mon's Huachuca ferns by Mr, Davenport, who has sent me three 
fronds. They are all rather smaller than common Mexican speci- 
mens. One of them has uniformly monosorous pinnae, one shows 
here and here a second sorus, and the third has regularly three or four 
sori on most of the pinnse. Usually this fern has decidedly larger 
and more erect fronds than A, Trichomanes^ and the few large sori 
are along the lower edge of the pinnule.
