306 BOTANY. 
numerous, short-stalked, roundish or ovate, varying from nearly entire to 
pinnately lobed, the upper surface more or less sprinkled with stellate or 
innately divided white scales, the lower surface densely covered with 
ferruginous ovate scales, their margin paler or whitish and elegantly cili- 
ated.— Enum. Fil. p. 135. 
Texas to Arizona (Wright, Dr. Seguin, Rothrock, etc.) and southward to Chile. This Fern varies a 
good deal in size and in the shape of the pinnz, and includes N. levis, Mart. & Gal., and N. pruinose, 
Fée. The scales of the frond are very beautiful objects for the lower powers of a good microscope. 
** Fyond hairy or tomentose beneath. 
Notholzna ferruginea, Hooker. 
Rootstock creeping, covered with very narrow dark rigid scales; 
stalks tufted, blackish, or very dark brown, at first woolly ; fronds 8-12 
inches high, narrowly lanceolate, pinnate; pinnee numerous, 4—7 lines long, 
ovate, rather obtuse, pinnatifid with 6-8 closely set little lobes on each side, 
hairy above, but with the green surface visible, beneath densely tomentose, 
the wool at first whitish, but becoming ferruginous; sporangia deep brown.—

Western Texas and New Mexico, collected by the Botanists of the Mexican Boundary Survey. 
Sanoita Valley, Arizona, Rothrock. Found also throughout Mexico and as far south as Ecuador and 
eru. In Chile it is replaced by the nearly allied N. hypoleuca, Kunze. 
Notholzna Parryi, D. C. Eaton. 
Rootstock short, inclined, laden with rather rigid narrow scales, which 
are fulvous, with a blackish midrib; stalks 2—4 inches high, dark brown, 
minutely striated, pubescent with whitish jointed spreading hairs; fronds 
as long as the stalks, oblong-lanceolate, tripinnate, lower pinnze distant ; 
ultimate segments crowded, roundish-obovate, about one line long, densely 
covered above with entangled white hairs, like those of the stalks, and 
beneath with a still heavier pale-brown tomentum; sporangia blackish, 
when ripe projecting beyond the margin of the segments.—Am. Naturalist, 
ix, p. 351.

Dec. 1875. This has very much the habit and appearance of Cheilanthes lanuginosa, Nutt., but the absence 
of anything like an involucre makes it a true Notholwna, and the denser and coarser character of the 
pubescence will also serve to distinguish the present plant.
