CHEILANTHES. 103 



47. Ch. Fendleri, Hook. ; small, caudex creeping scaly, 

 stipites sparse scattered slender brown scaly with subulate 

 appressed scales, in the main and secondary racbises the 

 scales become more copious broader ovate acuminate white 

 glossy brown at the base, fronds 2 — 3 inches long ovate-lan- 

 ceolate subcoriaceous pale green quite glabrous on both sides 

 tripinnate, primary pinnules ovato-lanceolate obtuse, pinnules 

 rather large for the size of the frond convex broad cuneate 

 sessile somewhat decurrent retuse at the apex entire or 2 — 3- 

 lobed, the margins of the lobes merely incurved scarcely con- 

 fluent and forming the involucres. (Tab. CVII. B.) 



Hah. New Mexico, Fendler, in PI. Nov.Mex.n. 1015, (1847). — In many 

 respects this species of Cheilanthes approaches the Lendigera-group : but it 

 is the smallest of that section, and has the pinnules larger than any. There 

 are no hairs on this plant whatever ; where the scales are discontinued on 

 the under side, as at the secondary pinnae, the pinnules are seen to be quite 

 glabrous, and the rachises even of the primary piunse have no scales or 

 clothing of any kind, and are of the same texture and pale green colour as 

 the pinnules. 



48. Ch. speciosissima, Alex. Braun ; stipes 3 — 4 inches 

 long squamose with copious large ferruginous lanceolate 

 spreading scales, the same scales are continued but diminish- 

 ing in size upwards on the main rachis and on the partial 

 rachises and becoming rather chaffy hairs, frond ample 

 broad-lanceolate acuminate 1^ — 2 feet in length coriace- 

 ous rigid bipinnato-pinnatifid ferruginously hairy on both 

 sides but especially beneath, primary pinnae approximate li- 

 near-oblong acuminate sessile 2 — 4 inches long pinnatifid at 

 the apex, secondary pinnules oblong obtuse broadest at the 

 base pinnatifid, lobes or segments oblong obtuse entire the 

 margin much recurved, involucres continuous formed of the 

 recurved margins become membranaceous and more or less 

 cut or jagged at the edge. — Alex. Braun, in Kunze, Analect.

Hab. Mexico, Karwinski. Near Real del Monte, Hartweg. Coscoma- 

 tepee, Vera Cruz, Linden, n. 44. Peak of Orizaba, 12,000 feet elevation, 

 Galeotti. — Kunze may well speak of this noble plant as " Filix vere spe- 

 ciosissima : " — some of our specimens show that they attain a length of 

 frond exclusive of stipes, of 2 feet. Yet this species has been referred by 

 Martens and Galeotti to Ch. scariosa, Kaulf. (Acrostichum scariosum, 

 Swartz and Willdenow). Kunze's figure and description are alike excellent-
