racJiiscs slightly fibrillose, and both sides densely pubescent and glandular ; 

 vcinlets 8-10 on a side ; sori large, subniarginal. — Hk. Sp. 4. j)- 102. 



Hab. Mexico to Brazil and Peru. 



32. N. (Last.) vcstitum, Baker; st. n-12 in. 1., stout, densely coated with 

 woolly lanceolate scales ; //■. 1-2 ft. 1., G-10 in. br. ; pvince 3-5 in. 1., |-1 in. br., 

 cut down to a narrowly-winged ruchis into blunt, entire, falcate lobes 2 lin. br. ; 

 texture herbaceous ; rac/n's of the pinnre densely clothed with l)road furfuraceous 

 scales ; veinlcts 0-8 on a side, the sori close to the midrib. — Polyp. Iladdi. 

 N. Raddianum, Hi: Sp. 4.p. 98. t. 245. 



Hab. S. Brazil. — The Mauritian A. nitidum, Bory, is like this, except that the scales 

 are narrower and finer, and with tiiis a Brazilian phint, marked "A, sqiiainirjerum" by 

 Mettenius, agrees. 



."S. N. (Last.) crinititm, Desv. ; st. 6-12 in. 1., stout, densely clothed with 

 louij, purplish-brown, fibrillose scales 'jfr. 12-24 in. 1., 8-12 in. br., ovate-deltoid ; 

 pinnce 4-G in. 1., 1 in. br., cut down nearly to the rachis into slightly falcate, 

 linear-oblong lobes 2 lin. br. ; lower pinnce deflexed ; texture herbaceous ; rachis 

 and midrib more or less fibrillose ; veinlcts 9-12 on a side ; sori medial. — Hk. Sp. 

 4. 2>. 111. {in pa}-t). A. sulcatum, A"//". 



Hab. jNIauritius and Bourbon. — This and the two preceding resemble one another 

 closely in habit, texture, and shape of the lobes, and in all three the involucre is tliin 

 and fugacious. In^. pauciflorum, Kaulf., the scales are fewer, and not so distinctly 

 subulate, but it does not seem clearly separable. 



."4. N. (Last.) Ctenitis, Baker ; st. more than 1 ft. 1., clothed throughout with 

 black and ferruginous scales ; fr. 2 ft. 1., 1 ft. or more br. ; pinna; 8-9 in. 1., 

 Ij-H in. br., cut down nearly to the rachis into obtusely-toothed lobes, the lower 

 ones with a space between them, the lower pinna? stalked ; texture sul)coriaceous ; 

 upper surface with scattered short ferruginous hairs, lower with dark scales on 

 the midrib ; vcinlets about 15 on a side ; sori near the main veins ; invol. per- 

 sistent, glabrous. — Aspid. Kse. Mctt. Asp. p. 91. 



Hab. Brazil. 



35. N. (Last.) vclleum, Baker ; st. G in. 1., densely clothed, especially at the 

 base, with long linear scales ; /;'. 1^-2 ft. 1., 6-9 in. br. ; pinnce 3-4 in. L, |-1 in. 

 br., cut down to the rachis into linear-oblong lobes 1^-2 lin. br. ; texture 

 herbaceous ; under side naked ; rachises densely clothed with long, pale, bright- 

 brown fitirillose scales ; veinlcts 7-8 on a side, the sori close to the midrib. — 

 Aspid. Willd. N. aureo-vestitum, Hk. Sp. A. p. 101. t. 246. 



Hab. West Indies. — This most resembles the three preceding, but the frond is nar- 

 rower and more elongated, and the clothing of the rachis is quite peculiar, 



36. N. (Last.) canpense, Hk. ; st. 1 ft. or more 1., firm, clothed principally at 

 the base with long, dense, linear scales ; fr. 1^-2 ft. 1., 8-12 in. br. ; pinnce 4-6 

 in. 1., 1 in. br., cut down to a broadly-winged rachis into close, blunt, entire 

 lobes 2 lin. br., the lower lobes reduced and lower pinnre slightly stalked ; 

 texture firm ; rachis nearly and both sides quite naked ; veinlcts 12-15 on a side ; 

 sori medial ; iiivol. small, fugacious. —Hk. Sp. 4. p. 99. N. Tarapotense, Hk. 

 Sp. 4. p. 107.
