-STATE OP CHIHUAHUA—
4=42 Cfreilanthes leucopoda, Link.
442—'Cheilanth.es
Mt; March.
This and 457 appear to me very doubtfully distinct
seemingly differ only in one plant being moife délicate t|
other. 442 has heretofore been thought to be more delidâte, bul?
in Mr. Pringle’s collection itis more robust. Judging from the
number of specimens it appears to have been abundant, thriving
Vigorously on exposed limestone ledges, while the more delicate
457 grew sparingly on cool, shaded* cliffs.
The differences between the two are, on their face, exceedingly
slight. Both are nearly equally glandular pubescent ; the differ-
ence in the color of their stipites is no greater than in many other
ferns—in 442 they are usually straw-colored, but in sotner plants
they are <fuite as brown as in 45/-i-and othei* differences may
be readily accounted for by the character of different habitats,
and varying conditions of growth. But while I am strongly in-
clined to consider these two ferns as merely good forms of one
species, I havl Hot made an examination thorough enough to
justify so uniting them here.
