Science, July, 1848, p. 82, and Die Farrnkriuter, ii, p. 57, t. 204. Cheil- 
anthes dealbata, Pursh. 
From the Upper Missouri (Pursh, Nuttall) and Kansas, where it is rather common, “chiefly on the 
perpendicular faces of dry calcareous rocks, where it is sheltered by overbanging projections” (Hall, 
Parry), to New Mexico (Mrs, Sumner) and Arizona, Parry, Rothrock. I have also seen specimens said to 
have come from Texas. The Kansas specimens are very delicate, only 3-4 inches high, and correspond 
exactly with Kunze’s figure, but those gathered in Sanoita Valley, Arizona, by Dr. Rothrock, are much 
taller (8-9 inches), and have a stout wiry stalk, looking much more like a transition. towards N. nivea, 
They have, however, the frond fully quadripinnate, and the very minute segments of the present species. 
Notholzwna Fendleri, Kunze. 
Rootstock short, thick, chaffy, with ferruginous scales; stalks densely 
tufted, dark-brown, polished, 3-5 inches long; rachis and all its branches 
similar, but flexuous and zigzag; frond broadly deltoid-ovate, 3-5 inches 
long, and nearly as broad, 4—or nearly—5-pinnate below, gradually simpler 
above; pinnze alternate; ultimate pinnules oval or elliptical, 1-14 lines long, 
simple or 3-lobed; upper surface green, often glandular or dotted with 
white; under surface white-pulveraceous.—Die Farrnk. ii, p. 87, t. 136. 
Clefts of rocks, Colorado, New Mexico, and Arizona, Fendler, [all § Harbour, Brandegee, Parry, 
Wolf, Palmer. A larger plant than the last, and easily distinguished from it by the zigzag and usually 
much entangled branches of the rachis. 
* * * * Frond naked beneath, pinnately compound. 
Notholzna tenera, Gillies. 
Stalks tufted, brownish, smooth, and shining; fronds 3-4 inches long 
{larger in Chilian plants], ovate-pyramidal, 2—3-pinnate, sub-coriaceous; 
pinnz mostly opposite, distant, the lower ones somewhat triangular; ulti- 
mate pinnules ovate, often sub-cordate, obtuse, scarcely 1 line long, smooth 
and naked on both surfaces; texture rather delicate—Bot. Mag. t. 3055 ; 
Kunze, Die Farrnk. i, p. 44, t. 22; Hook. Sp. Fil. v, p. 112. 
Crevices of perpendicular rocks. Southern Utah, Dr. Parry, May, 1874. Like the last two species, 
this is closely related to N. nivea, the principal difference in this case being in the absence of the white 
powder. It occurs, also, in Bolivia and in Chile. Specimens with simply pinnate fronds, and larger, 
roundish pinnules, were collected with the more compound form in Southern Utah by Dr. E. Palmer in 
1877.
