150 30. PELL^EA, ALLOSORUS. 



Hab. Madagascar, Mauritius, Macalisberg, Ceylon, Neilgherries (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. 



26. P. (Allo.) andromedcefolia,'Fee; st. 6-9 in. 1., strong, erect, pale-brown, 

 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 ; pinnae rigid, erecto-patent, 

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

 which are sometimes slightly branched ; uU. divisions 1^-2 lin. 1., linear-oblong, 

 blunt with enrolled edges ; texture coriaceous ; rachis and both surfaces naked, 

 the wrinkled invol. scarcely changed from the substance of the frond, and some- 

 times nearly meeting edge to edge. Hk. Sp. 2. p. 149. /3, C. pubescens, Nutt. ; 

 rachis and pinnules pubescent. 



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



27. P. (Allo.) pulchella, Fee ; a?, densely tufted, 2-3 in. 1., wiry, erect, polished, 

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

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

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

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

 ments much enrolled, and the broad invol. permanently rolled over the sori.

Hab. Andes, from New Mexico southward to Peru. 



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

 polished ;fr. 6-12 in. 1., 4-9 in. br., deltoid, tri- or quadripinnatifid ; lowest pinna? 

 deltoid, with ihepinnl. 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 ; rachis 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.

 p. 107. 



Hab. Cape Colony, Kaffraria, Natal, Madagascar, and Cameroon Mountains. P. Bojeri 

 appears to be a slender form with a slightly fibrillose rachis. Mettenius refers here 

 C. triangula, Kunze, but Dre'ge's specimens are in part C. multifida. 



29. P. (Allo.) 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 ; pinnae 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 subcoriaceous, both sur- 

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

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

 j3, P. cuneata, J. Sm. ; ultimate segments oblong-acute, |- in. 1., in. br., 

 cuneate at the base. Cheilanthes cuneata, Link. Hk. Sp. 2. p. 3 07. 



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

 also a broad-leaved form of this. 



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

 dark chesnut-brown, naked ; jr. 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
