Hab. JMadagasoar, Mauritius, Maoalisberg, Ceylon, Neilgberries (3-5,000 ft.). — This 

 comes near P. hastata in size and habit, but the segments are narrower, and the involucre 

 is that of this section,

 naked, densely clothed at the base with linear subulate reddish-brown scales ; fr. 

 6-12 in. 1., 3-6 in. br., ovate, tri- or quadripinnate ; pinnoi rigid, erecto-patent, 

 lanceolate-deltoid, the lowest with several linear oblong pinnL, the lower segm. of 

 which are sometimes slightly branched ; ult. divisions lJ-2 lin. ]., linear-oblong, 

 blunt with enrolled edges ; texture coriaceous ; racMs and both surfaces nak^d, 

 the wrinkled in.vol. scarcely changed fi'om the substance of the frond, and some- 

 times nearly meeting edge to edge. — H'k. Sp. 2. p. 149. j3, C. pubeaeens, Nutt. ; 

 rachls and pinnules pubescent. 



Hab. California, southward along the Andes to Chili ; Cape Colony.

 dark chesnut-brown, naked ; fr. 3-6 in. 1., 1-3 in. br., oblong, tripinnate ; lower 

 pinruB deltoid ; pinnl. lanceolate, the very deciduous ult. segm. oblong, blunt, 

 scarcely more than \ in. 1. by half as broad ; racMs rigid and polished like the 

 stipe ; texture coriaceous, both surfaces green, naked, the edges of the fertile 

 segments much enrolled, and the broad invol. permanently rolled over the Bori. — 

 Hk. Sp. 2. p. 160. 



Hab. Andes, from New Mexico southward to Peru. 



28. P. (Alio.) consobrina, Hk. ; St. strong, erect, 6-12 in. 1., naked, dark-brown, 

 polished ; fr. 6-12 in. L, 4-9 in. br., deltoid, tri- or quadripinnatifid ; lowest pinnae 

 deltoid, with the pinnl. of the lower side larger than the others, these latter usually 

 cut down into several lanceolate or deltoid pinnatifid segm. ; simple ult.' divisions 

 linear- oblong, sometimes J in. 1. ; texture coriaceous ; racMs and both sur- 

 faces naked ; sori in a continuous line along the margins ; invol. moderately 

 broad, membranous, the edge of the segments often enrolled. — Hk. Sp. 2. p. 145.

Hab. Cape Colony, Kaffraria, Natal, Masoaren Isles, Cameroons, and Abyssinia. — 

 P. Bojeri appears to be a slender form with a slightly fibrillose rachis. Metteniua refers 

 here C. triangula, Kunze, but Dr^ge's specimens are in part C. muUiJlda. 



29. P. (Alio.) angustifolia, Baker ; st. tufted, 6-12 in. 1., strong, erect, naked, 

 dark chesnut-brown, polished ; fr. 6-12 in. 1., 3-6 in. br., deltoid-oblong, quadri- 

 pinnatifid ; pinnce 2-4 in. 1., lanceolate-deltoid ; pinnl, often cut down to the 

 rachis into numerous linear segm. with enrolled edges, the terminal ones much 

 the largest (^ in. or more 1.) ; rachis polished ; texture subcortaceous, both sur- 

 faces pale-green, the upper slightly hairy ; invol. broad, membranous, rolled 

 over the sori. Cheil., H. B. if. P. decomposita, Hk. Sp. 2. p. 151. t. 119. B. 

 — /3, P. cuneata, J. Sra. ; ultimate segments oblong-acute, J in. 1., J in. br., 

 cuneate at the base. — Cheilanthes cuneata, Link. Hk. Sp. 2. p. 107. 



Hab. North of Mexico southward to Venezuela. — C, dicerophylla, Kunze, seems to be 

 also a broad-leaved form of this, 



30. P. (Alio.) glauca, J. Sm. ; st. tufted, 4-8 in. 1., strong, -erect, polished, 

 dark chesnut-brown, naked;/?-. 3-4 in. each way, deltoid, quadripinnatifid ; ■ 

 lowest pinnce much the largest and the pinnl. on the lower side larger than the 

 others, lanceolate-deltoid, cut down to the rachis into segm. which are again cut 

 down to the rachis below ; ult. divisions about ^ in. 1., linear-oblong, with 

 enrolled edges, more or less crenate ; texture coriaceous, upper surface green 

 and naked, lower surface and the rachis tomentose ; invol, coriaceous, rolled
