48. POLYPODIUM, CYRTOMIPHLEBIUM, GONIOPTERIS. 313 



53. P. (Pheg.) Vogelii, Hk. ; st. l|-2 ft. 1., naked, substramineous, with long 

 linear scales at the base ; Jr. ample, probably 4 ft. or more 1., 2 ft. br. ; lowest 

 pinnce 1 ft. 1., the pinril. of the lower side much the largest, and the lowest larger 

 than the others, which are lanceolate, 4-5 in. 1., \\ in. br., cut down nearly to 

 the rachis into oblong toothed lobes -^ in. br. ; texture subcoriaceous ; rachis 

 naked ; under side only slightly hairy on the main veins ; veinlets of the lohe_s 

 forked ; sori medial. Hk. Sp. 4. p. 721. (in part}. 



Hab. Fernando Po, Vogel. This comes near P. connexum, but the sori are larger, and 

 the texture is thicker. The Cape Verde plant is a large form of N. Filix-mas. Gymno- 

 gramma subsimilis, Hk. Sp. 5. p. 142. t. 293, is apparently this species, with the sori 

 not fully developed. 



54. P. (Pheg.) nigritiarium, Baker ; st. l|-2 ft. 1., naked, or upwards sub- 

 villose ; Jr. 3-4 ft. 1., 2 ft. or more br. ; lower pinnce I ft, 1., the pinnl. of the 

 lower side lanceolate, 4-8 in. 1., 1^-2 in. br., cut down to the rachis below into 

 distinct oblong unequal-sided segm. with deep close entire lobes ; texture herba- 

 ceous ; rachises of the pinnl. densely villose and under side less so ; veinlets 

 pinnate in the lower lobes ; sori submarginal. 



Hab. Gathered by Barter in the Niger Expedition, and by Mann at Fernando Po. 



55. P. (Pheg.) Keraudrenianum, Gaud. ; st. % in. thick or more, stramineous 

 or brownish, polished ; Jr. 12-15 ft. 1., subscandent ; pinnce distant, the lower 

 ones 1-3 ft. J., 6-15 in. br. ; pinnl. lanceolate, often deflexed, cut down nearly or 

 quite to the rachis into lanceolate or linear-oblong entire or pinnatifid segm. ; 

 texture herbaceous ; rachises stramineous ; both sides naked or the under one 

 villose ; veinlets pellucid, forked ; sori submarginal. Hk. Sp. 4. p. 268. 



Hab. Sandwich Isles and Java. P. procerum, Brack., is evidently a form of this, which 

 varies much in cutting, and resembles P. distans on a large scale. 



Cyrtomiphlebium. Venation of Cyrtomium, i. e., with the contiguous groups 

 "* *" "r. TAB. 48. Fig. f. Sp. 56. 



56. P. (Cyrt.) dubium, Hk. ; st. tufted, 12-18 in. 1., densely clothed at the 

 base with large firm scales, and upwards with smaller ones ; Jr. 2-3 ft. 1., 6-12 

 in. br. ; lower pinnce 3-6 in. 1., f-1^ in. br., unequal-sided, the apex acuminate, 

 the edge finely toothed, the inner edge on the upper side nearly parallel with the 

 stem, on the lower side oblique ; texture coriaceous ; rachis and both sides nearly 

 naked ; sori copious, roundish or oblong. Hk. Sp. 5. p. 15. 



Hab. Andes of Ecuador and Peru. Exceedingly like some of the forms of Aspidium 

 falcatum in habit and texture. The bipinnatifid plant placed here in "Species Filicum" 

 appears to be a form of P. platyphyllum, with slightly anastomosing venation. 



Goniopteris, Presl. Venation of Eunephrodium, i. e., veins pinnate, with 

 the lower veinlets of contiguous groups joining. Sp. 57-80. TAB. 48. f. e. 



* Pinnce entire or the edge slightly crenate. Sp. 57-64. 



57. P. (Goniopt.) simplicifolium, Hk. ; st. tufted, strong, 2-4 in. 1., villose 

 upwards ; fr. 6-12 in. 1., with a lanceolate-acuminate entire apex 1-1 in. br., 

 and at the base 1-6 small blunt spreading entire distinct pinnce ; texture sub- 

 coriaceous ; midrib beneath hispid, and the prominent veins slightly so ; main 

 veins 2 lin. apart, all the veinlets joining ; sori minute. Hk. Sp. 5. p. 2. 

 Nephrodium, Hk. 2nd Cent. t. 19. Abacopteris, Fee. 



Hab. Philippines, Cuming, 315 ; Fiji, Seemann, 736. 



58. P. (Goniopt.) debile, Baker ; st. slender, slightly hairy ; fr. 6-12 in. 1.,
