sub Asp.) sori in a line close to the midrib ; rachis and under side nearly 

 naked ; lower pinnae reduced suddenly. 



Hab. N". India to Ceylon, Mauritius, and Bourbon. The Mascaren plant (A . stipulaceum, 

 Mett.) has the lowest lobes sometimes dilated and pinnatifid, like those of N. macrourum. 

 Dr. Thwaites regards tylodes and ochtkodes as probably distinct species. The two are 

 figured by Beddome, Fil. S. Ind. t. 106-7. 



54. N. (Last.) limbatum, Desv. ; st. 4-6 in. 1., naked, glossy ; fr. 2-3 ft. I., 

 G-12 in. br. ; pinnce 3-6 in. 1., f- in. br., with a gland at the base beneath, cut 

 down very nearly to the rachis into slightly falcate, entire, linear-oblong lobes 

 1-1^ lin. br. ; texture papyraceo-herbaceous ; rachis stramineous and both 

 surfaces nearly naked ; veinlets 6-10 on a side, the prominent persistent invo- 

 lucres protruding beyond the edge. Hk. Sp. 4. p. 94. Amauropelta, Kze. 



Hab. West Indies. Easily recognizable by the character of the involucre, on account 

 of which Kunze made for it a new genus. 



55. N. (Last.) resino-fcetidum, Hk. ; st. 1-2 ft. 1., naked, scaly below ; fr. 3-4 

 ft. 1., 12-18 in. br. ; pinnce 6-9 in. 1., 1 in. br., cut down nearly to the rachis into 

 close, linear, acute, entire lobes | in. br., with a space between them, furnished 

 with a gland at the base, the lower ones reduced to mere auricles ; texture 

 coriaceous ; rachis and under side naked or finely villose ; veinlets 10-15 on a 

 side ; sori submarginal ; edge reflexed. Hk. Sp. 4. p. 105. (in part). 



Hab. Andes of Ecuador, Spruce ; Bolivia, Mandon. This is nearest N. Sprengelii, but 

 is a larger and more rigid plant, with very numerous lobes and veinlets. It is said to 

 have an unpleasant resinous scent when growing. 



56. N. (Last.) Sprucei, Baker ; st. 1 ft. or more 1., nearly naked ; fr. 2-3 ft. 1., 

 8-1 2 in. br. ; pinnce 4-6 in. 1., 1 in. br., cut down nearly to the rachis into entire, 

 spreading lobes 2 lin. br., with a considerable space between them, furnished 

 with a gland at the base, the lower ones dwindling down gradually ; texture 

 papyraceo-herbaceous ; rachis slightly villose ; under side naked ; veinlets 8-10 

 on a side ; sori nearer the midrib than the edge ; invol. large, distinct. 



Hab. Andes of Ecuador, Spruce. Distinguished from the last by its more herbaceous 

 texture, broader lobes, fewer veinlets, and medial sori. 



57. N. (Last.) Bergianum, Baker ; st. 6-12 in. 1., naked or finely villose; fr. 

 1^-2 ft. 1., 6-10 in. br. ; pinnce 8-5 in. 1., f in. br., cut down nearly to the rachis 

 into close, entire lobes in. br. ; texture herbaceous ; rachis and under side more 

 or less villose ; veinlets 6-8 on a side ; sori medial ; invol. small, fugacious. 

 Polyp. Schlecht. 



Hab. Cape Colony and Natal. Perhaps a variety of N. patens, but the lower pinnae 

 reduced gradually* A. Gueintzianum, Mett., differs by the presence of a gland at the 

 base of the pinnae beneath. 



58. N. (Last.) tomentosum, Desv. ; st. densely tufted, 3-4 in. 1., finely villose ; 

 fr. 1-2 ft. 1., 6-10 in. br. ; pinnce 3-5 in. 1., |-l*in. br., with a gland at the base 



beneath, cut down nearly to the rachis into linear-oblong lobes, the lowest of 

 which are often larger than the others ; texture herbaceous ; lower pinnae distant, 

 and dwarfed down to mere auricles ; rachis and under surface villose ; veinlets 

 8-12 on a side; sori nearly terminal. Polyp. Thouars. N. thelypteroides, 

 Hk. Sp. 4. p. 95. (non Michx.}. A. riparium, WtUd. 



Hab. Mauritius, Bourbon, Tristan d'Acunha. This may be a luxuriant villose variety 

 of conterminum. 



59. N. (Last.) globuliferum, Hk. ; st. tufted, smooth, naked, glossy ; fr. 1^-2 

 ft. 1., 1 ft. br. ; pinnce 4-6 in. 1., f in. br., cut down to a broadly-winged rachis
