cies is well known, the most obvious difference, as men- 
tioned by Eaton, consisting in the copious covering of 
slender-pointed but long, coarse, persistent, septate 
hairs of N. Parryi, the upper surface of the blades of 
C. Feei being Teenely furnished with w aie webby 
hairs” an never hirsute-tomentose.’’ Moreover, 
C. Feei has the margins of the segments narrowly but 
regularly recurved, while in N. Parryi the margins are 
slightly if at all recurved, the segments being in fact 
nearly flat, as in C. Cooperae. Although the retention 
of N. Parryi in Notholaena appears never to have been 
seriously questioned, the plant might with about equal 
propriety be placed in Cheilanthes, because of its some- 
what clavate vein-tips. A comprehensive revision of 
Notholaena and Cheilanthes and their near allies is 
urgently needed, including especially the numerous trop- 
ical species. 
Notholaena Parryi, described originally from St. 
George, in southwestern Utah, is known to range thence 
to south-central Arizona and the desert region of south- 
ern California. It ascends to 1,740 meters in the Pana- 
mint Mountains, Inyo County, California, but is said 
by Parish to be more abundant at low altitudes, as, for 
example, at Palm Springs, altitude about 150 meters, 
on the eastern slope of the San Jacinto Mountains.
