308 BOTANY. 
Notholzna Hookeri. 
Rootstock short, creeping, densely covered with rigid lanceolate dark- 
brown scales, with a strong midrib; stalks tufted, 4-8 inches high, reddish- 
brown, wiry, smooth and shining, the base only with a few ovate scales; 
frond 2-3 inches long and broad, almost regularly pentagonal, composed of 
three divisions; the middle one slightly stalked, rhomboid-ovate, pinnatifid 
into a few oblong toothed segments, of which the second pair is larger 
than the first; the side divisions sessile, deltoid, pinnatifid on the upper side, 
much as is the central division, but each bearing on the lower side a single 
very large pinnatifid basal segment, and above it smaller segments like 
those of the upper side; upper surface green, lower surface covered with a 
pale-yellow powder; sporangia sub-marginal; the edge of the frond 
slightly recurved.—N. candida, var. 5-fido-palmata, Hooker, Sp. Fil. v, p. 
111. N. cretacea, D. C. Eaton in Botany of Mexican Boundary, and in 
Bulletin of the Torrey Botanical Club, iv, p. 18; not of Liebmann! 
Western Texas to El Paso, C. Wright, 821. New Mexico, in several places, Bigelow, Schott, Rothrock, 
Mrs. Sumner. Not seen in California, for “La Cuesta” is in New Mexico. My own recently — 
notes on the North American Ferns of the Hookerian herbarium show that Liebmann’s N. cretacea is a 
yellow-powdered form of N. candida, ard Mr. Baker is doubtless right in referring Cheilanthes paiering 
Mettenius, to the same species. As Sir William Hooker has remarked in Species Filicum that the pres- 
ent is ‘‘ probably a distinct species,” I can not do better than to call it by his name, rejecting a incon- 
venient appellation under which he distinguished it as avariety. In general appears nce it is h like 
small specimens of Gymnogramme triangularis., From N. candida it differs in several sei. most 
markedly perhaps in having the second pair of primary pipne or segments me cingiee smaller than the 
third pair, whereas in the former this second pair is larger than the pair next above 
ate XXX represents a plant of ordinary size. Fig. 1, a scale of the sciehecks magnified six 
diameters; fig. 2, a scale from the base of the stalk ; fie 3, a segment of one of the pinne, showing the 
sporangia and the slightly recurved margin. 
++ Fronds 2-4 pinnate, the primary and secondary pinne distinctly 
stalked, ultimate divisions very small. 
Notholzna dealbata, Kunze. 
Stalks densely tufted, wiry or capillary, nearly black, polished; rachis 
and all its branches very straight, capillary, black and shining; frond del- 
toid-ovate, 4-pinnate at the base, gradually simpler above; pinne mostly 
opposite; ultimate pinnules 3-1 line long, oval and entire, or some of them 
3-lobed; upper surface green, under surface white- pulveraceous.—Am. Jour.
