rj.l. P. (Plieg.) Vogelii, Ilk. ; st. li-2 ft. 1., naked, siil)stramiiie()us, witli long 

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

 jiinmt' 1 ft. 1., i\\e 2>innl. of the lower side much the largest, and the lowest larger 

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

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

 naked ; zuuier side only slightly hairy on the main veins ; veinlets of the lobes 

 forked ; sari medial. — Ilk. Sp. 4, p. 721. {in part). 



Ilab. Fernando Po, Vogcl. — This comes near P. conncxum, but the sori are larger, and 

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

 fjramma mhsimills. Ilk. Sp. 5. p. 142. t. 293, is apparently this species, with the sori 

 not fully developed. 



54. P. (Pheg.) nigritiannm, Baker; st. \\-2 ft. 1., naked, or upwards sub- 

 villose ; fr. 3-4 ft. 1., 2 ft. or more br. ; lower jnnnce 1 ft. 1., the phml. of the 

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

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

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

 jiinnate 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 ; /r. 12-15 ft. 1., subscandent ; pinna; distant, the lower 

 ones 1-3 ft. 1., 6-15 in. hr. ; ^^2H?i^. 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. 208. 



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

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



§§ Cyrtomiphlebium. Venation of C//rtomium, i. e., with the contiguous groups 

 uniting irregularly. Tab. 48. Fig. f. Sj). 56. 



5G. P. (Cyrt.) dubium, Hk. ; st. tufted, 12-18 in. 1., densely clothed at the 

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

 in. hr. ; lower pinnce 3-G in. 1., |-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 ; racliis and both sides nearly 

 naked ; son copious, roundish or oblong. — Ilk. Sp. 5. p. 15. 



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

 falcalum in habit and texture. The bipinuatifid plant placed here in "Species Filicum" 

 appears to be a form of P. plalijphyllum, with slightly anastomosing venation. It is 

 Phcgopteris dictyophylla, Mett.

 the lower veinlets of contiguous groups joining. Sp. 57-fjO. Tah. 48. f. e. 



* Pinnce entire or the edge slightly crcnate. 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 

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