exposed rocks, Upper Hondo, in June, 1885. 
Pellea flexuosa, Link.—Superb specimens, and very distinct 
from any forms of P. cordata, J. Sm. 
Pellea Wrightiana, Hook.—Typical plants, the smaller ones 
closely resembling P. ¢ernifolia, Link. 
Notholena candida, Hook.—A fine series of the typical form 
of this species, ranging from 2% to 15 inches in height, with 
laminz varying from 1 to 6 inches in length, 1 to 3% inches in 
breadth, and with from 2 to 8 pair of pinne; throughout all, 
- however, an almost stereotyped form of segment prevails. 
Aneimia Mexicana, Klotz.—Specimens large and fine, some 
of them showing exceedingly interesting forms of abnormal 
development. In one example, what should have been the sterile 
lamina has been almost transformed into a fertile panicle, the 
apices of the divisions alone remaining sterile and green. This 
specimen has in addition the usual pair of fertile spikes well 
developed. In another specimen each of the two fertile spikes 
consists of a simple green lamina with a marginal row of fruit on 
each side slightly inrolled, and only partially pinnatifidly divided 
into wholly fertile divisions at the extreme apex. 
Chetlanthes Lindheimeri, Hook.—This remarkable and ex- 
ceedingly beautiful fern seems to hold to its characters with more 
constancy than any other member of the group to which it be- 
longs, and is almost always easily determined, 
Cheilanthes lanuginosa, Nutt., Cheilanthes tomentosa, Link— 
some specimens near var. Eatoni, Davpt., Notholena Hookeri, 
D.C. Eaton, Notholena nivea, Desv., var. dealbata, Davenp., 
Notholena sinuata, Kaulf. and Asplenium parvulum, H. & G., 
also occur in this fine collection of ferns, which consists of some 
eighteen specimens in all. 
With the ferns came two forms of Selaginella rupestris, 
Spring, the pretty Se/aginella apus, Spring, with which our 
eastern botanists are familiar, and finely fruited specimens of Mar- 
stlia macropoda, A. Br. 
The whole collection was made during the botanical tour 
through southwestern. Texas, by Mr. Reverchon and wife, in 
May and June, 1885, which he has so any described in 
the Botanical Gazette for March, 1886,
