entire lobes on each side, the lowest pah- much the largest, deeply pinnatifid on 

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

 brown tomentum ; veinleis forked ; sori copious, marginal. — Polypodium, Si, 

 8p. 4. p. 229. Ic. t. 991. 



Hab. South Brazil, Gardner, 2390. — A very distinct species, with the habit ot 

 JDm'yopteris. 



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

 3-4 in. 1. ; /r. 1^-2 in. 1., 1-1| in. br., subdeltoid, with 2-3 pairs of distinct/)«K«(a 

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

 rachis at the base into oblong blunt repand pinnl., that on the lower side \-^ 

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

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



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

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



19. N. tenera, Gill. ; st. densely tufted, 4-6 in. 1., chesnut-brown, naked, glossy ; 

 fr. 3-6 in. 1., 1^-2 in. br., ovate, tripinnate ; pinnce distant, the lower ones deltoid ; 

 thepinnl. long-stalked, with blunt oblong segm. ^-1 lin. br. ; texture subcoriaceous ; 

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

 t. 3055. 



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

 it differs only by being without white powder beneath. 



S§ Cincinalis, X>as». Fronds coated beneath mth white or i/ellow 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. 6-12 in. 1., l-li in. br., simply pinnate ; pinnce sessile, ovate-oblong, blunt, 

 pinnatifid, with Wunt lobes ; texture subcoriaceous ; upper sv/rface pale-green, 

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

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



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

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



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

 black \fr. 4-6 in. 1., |-| in. br., bipinnatifid ; pinnce short-stalked, deltoid-oblong, 

 § in. 1., J in. br., deeply 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 sulphur-coloured meal ; sori 

 marginal, brownish. — Hk. Sp. 6. p. 109. 



Hab. Mezico 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 (0. Wright, 1076-6) 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 the rachis 

 at the base into oblong lobes ; lowest pair with the lov/est pinnl. much prolonged, 

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

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

 sori black. — Pteris, Cm>. CheU. pulveracea, Hh. Sp. 2. p. 78. N. Candida, Hk.
