118 NOTHOCHL^NA. 



Hab. Mountains of Mexico, 5-8000 feet, '' Aschenhorn" Coulter, n. 1679, Lieb- 

 mann, Galeotti, n. 6565. — Very remarkable in the peculiar paleaceous scales 

 mixed witJi bright ferruginous tomentum and minute reddish apparently resinous 

 dots, with which the whole stipes, rachis, and under side of the frond are in- 

 vested. 



21. N. Pohliana, Kze. Herb. ; caudex creeping paleaceous 

 with close-pressed subulate scales, stipites 2-4 inches long 

 ebony-black as well as the rachises (which are also pubescenti- 

 villous), fronds 3^-4 inches long firm-membranaceous above 

 villous with long silky tawny hairs especially at the margin, 

 beneath more densely clothed with the same tawny hairs 

 mixed with branched and stellated ones but scarcely tomen- 

 tose, from a broad base (H-2 inches wide) pyramidal-oblong 

 gradually but bluntly acuminated bipinnate, lower primary 

 pinnae opposite all sessile oblong obtuse from nearly 1 inch 

 long at the base with 7-9 pinnules gradually shortening to 

 the apex where the pinnse are small and only lobato-pinna- 

 tifid, pinnules scarcely more than 2 lines long ovate obtuse 

 sessile entire sublobato-pinnatifid, the margins slightly re- 

 curved but not concealing the sori which form a continuous 

 brown line just within the margin. (Tab. CCLXXXVI. B.)

Hab. Brazil, Pohl. Serra de Natividade, Gardner, n. 'dbbl,Pohl. — A most dis- 

 tinct and very peculiar species. 



22. N. inaqualis, Kze. ; caudex short horizontal often 

 forming knots or bulbils from which the stipites originate 

 and which are also densely clothed with long narrow rufous 

 subulate soft scales, stipites clustered 3-5 inches long stout 

 intense ebeneous-black as well as the rachis, fronds coriace- 

 ous 3-5 inches long U-2 inches wide subtriangular-ovate acu- 

 minated subsericeo-pilose above densely rusty-tomentose be- 

 neath bipinnate below pinnate upwards, pinnatifid at the apex, 

 lowest primary pinnae obliquely triangular their lowest infe- 

 rior secondary pinnae being the longest and deeply pinnatifid 

 the rest of the primary ones are oblongo-lanceolate horizon- 

 tally patent deeply pinnatifid rarely again pinnate, pinnules 

 or segments oblongo-ovate obtuse entire, the margin scarcely 

 reflexed, sori near the margin concealed by the dense mass 

 of brown tomentum. — Kze. in Schk. Fil. Suppl. i. p. 146, t. 64. 

 /. 1. Cheilanthes, Metten. Cheil. p. 24. 



Hab. Macalisberg, S. Africa, Burke. — ^Well distinguished from N. Eckloniana 

 and A^. Marantm by the stouter habit and the dense brown tomentum, not scaly, 

 under side of the frond.
