stem ; under surface nearly naked ; sori small, placed at the base of the sinuses. 

 Hk. Sp. 2. p. 66. t. 90. C. 



Hab. Jamaica, Martinique, Venezuela, and banks of the Amazon. — Cuming's Philip- 

 pine plant, referred here in " Species Filicum," is Dicksonia moluccana. 



6. H. hostilis, Presl ; st. 1-2 ft. I., erect, tomentose, scabrous ; fr. ample, 

 quadripinnatitid ; lower pinnce 6-12 in. 1., 4-6 in. br., ovate-lanceolate ; 'pinnl. 

 lanceolate ; scgm. \-\ in. 1.; \ in. br., cut down nearly to the rachis throughout 

 into numerous linear-oblong tootlied ultimate divisions ; texture thinly herba- 

 ceous ; racMses tomentose ; sori very small, placed against the sinuses of the 

 ultimate divisions. — Hk. Sp. 2. p. 69. 



Hab. Jamaica, Cocos Island, and Peru. — A more delicate plant than II. repens, with 

 smaller and more deeply divided ultimate lobes, in which respect, as well as in general 

 habit, it very closely resembles the South African II. anthriscifolia. 



7. H. Purdieana, Hk. ; st. 6-9 in. 1., erect, strong, bright-brown, scabrous ; 

 Jr. 9-12 in. 1., 3-4 in. br., lanceolate, tripinnatifid ; largest pinnce 2 in. 1., 1 in. 



br., lanceolate-deltidd, cut down below to a narrowly-winged rachis, into 

 numerous linear-oblong deeply crenato-pinnatifid pinnules; texture herbaceous ; 

 rachis scabrous and densely clothed with brown filiform scales ; costa also 

 paleaceous ; sori nearly a line across, roundish, placed against the sinuses of the 

 pinnules.— /Z/l-. Sp. 1. p. 69. t. 91. B. 



Hab. New Granada ; gathered by Mr. Purdie. — I give this and the six preceding 

 species with great doubt as to how far they are distinct from one another, and with a 

 suspicion that some of them at least, like other plants which have been placed in Hypo- 

 lepis, will prove not really distinct from Polypodium rugulosuni. With regard to the 

 present one, for instance. Dr. Grisebach writes (Flora Brit. West Indies, p. 67), " Not to be 

 distinguished from P. rugulosum but by the specially transformed involucral appendages, 

 and probably passing into that widely-ranging species." Sir W. Hooker has expressed 

 the same doubt with regard to H. distans ; and reference may be made also, in connec- 

 tion with the same point, to Dr. Hooker's remarks in the Floras of New Zealand and 

 Tasmania. 



8. H. 2y(t}'(i^felogratnma, Hk. ; st. 2-4 ft. 1., strong, scabrous and prickly, but 

 scarcely pubescent; fr. 10-20 ft. 1., deltoid ; pinnce 1-3 ft. I., ovate-lanceolate; 

 pinnl. 6-9 in. 1., not much over 1 in. br., linear-lanceolate, with numerous linear- 

 oblong seg?n. about 9 lin. 1., 3 lin. br., which are sinuato-dentate and have about 

 their own l)readth between them ; texture subcoriaceous ; rachises like the stipes ; 

 so7-i sometimes 12 to a segm., placed at the sinuses. — Hk. Sp. 2. p. G5. t. 98. A. 

 Cheilanthes scabra, Karst. C. Radula, Kunze. 



Hab. Tropical America, from Guatemala southward to Brazil and Peru. — The segments 

 are much larger than in any of the preceding, more coriaceous in texture, with the sides 

 parallel for some distance and the point blunt, the veins beneath prominent. 



9. H. millefolium, Hk. ; rhizome stout, wide-creeping ; st. about 6 in. I., erect, 

 pale-brown, glossy, scarcely scabrous ; fr. 1 ft. or more 1., 4-6 in. br., ovate- 

 triangular, quadripinnatitid ; lower jnnnce erecto-patent, 4-6 in. 1., 1-2 in. br. ; 

 pinnl. ovate-deltoid, their segm. cut down nearly to the rachis into several small 

 sharply-toothed lobes ; texture herbaceous, under surface of the frond slightly 

 hairy ; rachises of the pinna; wintied ; sori small, roundish, placed in the lower 

 sinuses.— //-(:. Sp. 2. p. 68. t. 95. B. 



Hab. New Zealand. — A much smaller plant than II. tenuifulia, with the ultimate 

 segments more frequently and sharply toothed. 



10. H. Bergiana, Hk. ; st. tufted, 2 ft. ]., strong, erect, dark chesnut-brown, 

 tomentose ; fr. 12-18 in. 1., 6-9 in. br., deltoid, quadripinnatifid ; pinnce deltoid ; 

 pinnl. ovate-deltoid ; segm. ovate, -^-| in. 1., j-f in. br., cut down to the rachia
