entire lobes on each siile, the lowest pair much tlie largest, dcejily pinnatifid on 

 the lower side ; texture very thick ; under surface densely matted with yellowisii- 

 brown tomentum ; vcinlets forked ; sori copious, marginal. — I'ohpodium, Ilk, 

 aS>. 4. /;. 229. /c. ^ 991. 



Hab. South Brazil, Gardner, 2390. — A very distinct species, with the balit of 

 Doryoptcris. 



18. N. Buchanani, Baker ; st. tufted, slender, villose, bright chesnut-brown, 

 3-4 in. 1. ; fr. H-2 in. 1., 1-1^ in. br., subdeltoid, with 2-3 pairs of distinctyn'^JKe 

 below the deeply-pinnatifid apex, the lowest much the largest, cut down to the 

 rachis at the base into oblong l)lunt repand pimiL, that on the lower side j-'^ 

 in. 1. ; texture herbaceous; rachis axul both sides densely clothed with spreading 

 whitish or ferruginous hairs ; sori copious, brownish, quite marginal. 



Hab. Natal, Buchanan and McKen, 32. — This is very like the last in oiitHne, but is 

 more deeply divided, not so thick in texture, and though very hairy, yet not matted. 



19. N. tenera, Gill. ; st. densely tufted, 4-G in. 1., chesnut-brown, naked, glossy ; 

 fr.3-G in. 1., H-2 in. br., ovate, tripinnate ; jrinnce distant, the lower ones deltoid ; 

 the jn)i7iL long-stalked, with blunt oblong scgm. ^-1 lin. br. ; texture subcoriaceous ; 

 rachises rigid ; both surfaces naked ; sori brown. — Hk. Sp. 5. p. 112. Bot. Mag.

Hab. Chili and Andes of Bolivia. — Very doubtfully distinct from N. nivca, from which 

 it differs only by being without white powder beneath. 



§§ Cincinalis, Z>C5». Fronds coated beneath loith wldte or yellow powder. 



Sp. 20-27. 



20. N. (Cine.) trichomanoides, R. Br. ; rhizome thick, bulbiferous, the scales 

 black, fibrillose ; st. tufted, 2-4 in. 1., firm, erect, chesnut-brown, slightly scaly ; 

 fr. G-12 in. 1., |-H in. br., simply pinnate ; pinnce sessile, ovate-oblong, blunt, 

 pinnatifid, with blunt lobes ; texture subcoriaceous ; upper surface pale-green, 

 nearly naked, lower clothed with white powder and fine ferruginous woolly hairs, 

 the edge inflexed. — Hk. Sp. 5. p. 109. 



Hab. Jamaica and Cuba. — Differs from .ill the following by being tomentose as well as 

 farinose, and sometimes the powder is quite bidden beneath the tomentum. 



21. N. (Cine.) aji7iis,llk. ; st. tufted, 2-3 in. 1., wiry, glossy, naked, nearly 

 black ;fr. 4-6 in. 1., f-f in.br., bipinnatifid ; pin7ice shori-sta,lked, deltoid-oblong, 

 § in. 1., ^ in. br., deej)ly pinnatifid, with close entire lobes, the lower ones distant 

 and dwindling down gradually ; texture subcoriaceous ; upper surface and ebe- 

 neous rachis naked, lower densely matted with sul])hur-coloured meal ; sori 

 marginal, brownish. — Hi: >Sp. 5. p. 109. 



Hab. Mexico and Guatemala. — Our description is taken from a set of specimens 

 gathered by Messrs. Salvin and Godman, and does not entirely agree with that of Mette- 

 nius. In habit our plant agrees with the preceding, but is perfectly without tomentum. 

 Specimens from Cuba (C. Wright, 1075-6) are very similar, but are rather more slender, 

 and the farina is pure-white. 



22. N. (Cine.) sulphurea, J. Sm. ; rhizome creeping, the scales dense, rigid, 

 linear, nearly black ; st. tufted, 4-6 in. 1., ebeneous, wiry, naked ; fr. 2-3 in. each 

 way, deltoid ; upper pinnce simple, central ones lanceolate, cut down to tiie rachis 

 at the base into oblong lobes ; lowest pair with the \o\y&ii pinnl. much prolonged, 

 \ in. or more 1., pinnatifid or pinnate ; texture subcoriaceous ; upper surface 

 naked, pale-green, lower coated with white or yellow powder, the ribs ebeneous ; 

 sori black. — Pteris, Cav. Cheil. pulveracea, Hk. Sp. 2. p. 78. N. Candida, Hk.
