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 

 pinnately 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, Bothroek, vie.) and southward to Chile. This Fern varies a 

 good deal in size and in the shape of the pinna, and includes N. larvis, Mart. & Gal., and N.pruinoso, 

 Fee. The scales of the frond are very beautiful objects for the lower powers of a good microscope. 



**Frond hairy or tomentose beneath. 



Notholacna ferrMginea, 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 ; pinnse 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. —

 Mexican Boundary. 



Western Texas and New Mexico, collected by the Botanists of the Mexican Boundary Survey. 

 Sanoita Valley, Arizona, Bothroek. Found also throughout Mexico and as far south as Ecuador and 

 Peru. In Chile it is replaced by the nearly allied 2V. hypoleuea, Kunze. 



Notholrena 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 pinnae 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. 



Crevices of Basaltic rocks near St. George, Utah, Drs. C. C. Parry and E. Palmer. Mts. in desert 

 of Arizona (Dr. Palmer, May, 1876), and at Marengo Pass, San Bernardino County, California, Dr. Parry, 

 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 A T otholana, and the denser and coarser character of the 

 pubescence will also serve to distinguish the present plant.
