2 lin. br. ; tomentum of the rachis very short, and the pinnce naked. Hk. Sp. 5. 

 p. 105. 



Hab. Andes, from New Granada southward to Peru. Mettenius admits our three 

 varieties as species, and also /. scalaris, Kze., and /. rotundifolia, Fe'e, the latter a 

 robust plant, most like y, but with closer and rounder pinnae. 



GEN. 50. NoTHOCHLJENA, R. Br. 



Sori marginal, at first oblong or roundish, soon confluent into a continuous 

 marginal line, without a distinct involucre, but with the edge of the frond fre- 

 quently inflexed. Veins free in all the species. A small widely-dispersed genus, 

 differing from Cheilanthes only by the absence of a distinct involucre, and connected 

 with it by gradual intermediate stages. TAB. 6. /. 50. 



Eunothochlsena. Fronds not farinose beneath. Sp. 1-16. 

 * Fronds densely matted beneath ; stems robust. Sp. 1-11. 



1. N. Rawsoni, Pappe ; rhizome woody, wide-creeping, the scales dense, ad- 

 pressed, linear, black in the centre and ferruginous towards the edge ; st. 3-4 

 in. 1., wiry, erect, naked, dark chesnut-brown ; fr. 6-9 in. 1., \ in. br., simply 

 pinnate ; pinnce in distant pairs, nearly as broad as long, deeply pinnatifid ; 

 texture subcoriaceous ; upper surface pale-green, naked, lower densely matted 

 with ferruginous tomentum ; sori black, the edge not inflexed. Hk. Sp. 5. 

 p. 110. 



Hab. Namaqua-land, Eev. Mr. WJiitehead. 



2. N. sinuata, Kaulf. ; rhizome very thick, densely clothed with linear bright 

 ferruginous scales and bearing bulbs ; st. subtufted, 2-4 in. 1., firm, erect, chesnut- 

 brown, matted ;fr. 1-2 ft. 1., 1-2 in. br., simply pinnate ; pinnce short-stalked, |-1 

 in.l., j-^in. br., ovate or oblong, varying from* entire to deeply pinnatifid ; texture 

 thick, coriaceous ; upper surface green and slightly villose ; lower surface and 

 rachis densely coated with small linear ferruginous scales ; edge slightly inflexed. 

 Hk. Sp. 5. p. 108. Bot. Mag. t. 4699. 



Hab. New Mexico, along the Andes to Chili. 



3. N '. ferruginea, Hk. ; rhizome thick, bearing bulblike scaly buds, the scales 

 very dense, fibriilose, dark-brown ; st. subtufted, 2-4 in. 1., wiry, erect, black, 

 slightly matted ; fr. 6-12 in. 1., ^-1 in. br., simply pinnate ; pinnce sessile, ^-J 

 in. 1., ovate, deeply pinnatifid, with blunt lobes ; texture coriaceous ; upper surface 

 pale-green, villose, lower densely matted with ferruginous or nearly white tomen- 

 tum ; edge inflexed, slightly membranous ; sori black. Hk. Sp. 5. p. 108. 2nd 

 Cent. t. 52. 



Hab. West Indies and Mexico, along the Andes to Chili. This and the two preceding 

 may be distinguished from the rest of the group by having even the lower pinnae pinnatifid 

 only. 



4. N. lanuginosa, Desv. ; st. densely tufted, woolly, wiry, very short ; fr. 6-9 

 in. 1., 1-1^ in. br., oblong-lanceolate, bipinnate ; 'pinnce close, lanceolate, the 

 central ones the largest, with close, roundish or oblong, entire or 3-lobed pinnl. ; 

 texture herbaceous but thick ; both sides, especially the lower one, coated with 

 whitish or subferruginous tomentum ; rachis bright chesnut-brown, more or less 

 woolly. Hk. Sp. 5. p. 119. 



Hab. South Europe, from Spain to Syria, Greece, Madeira, Teneriffe, Cape Verde 

 Isles, Algiers, Temperate and Tropical Australia. Distinguished from the rest by its
