Hab. Sandwich Isles. This also has a habit not unlike that of the large forms of 

 Ftlix-mas. Our description is taken from living plants sent by Dr. Hillebrand.

Hab. Neilgherries, Capt. eddome.Tbis has altogether the habit and cutting ci 

 Sphceropteris barbata.

 furnished throughout with small ovate eoncolorous scales ; jr. 1^-2 ft. 1., 

 12-18 in. br. ; lowest pinnce deltoid, G-9 in. 1., 3-5 in. br. ; pinnl. of the lower side 

 the largest, with free lanceolate segm. \-\ in. 1., cut down nearly to the rachis 

 into toothed ligulate lobes under 1 lin. br. ; texture herbaceous ; rachises viscous- 

 pubescent, the hairs sometimes dense and ferruginous ; both sides nearly 

 naked ; sori small, usually one at the base of each ult. division ; invol. small, 

 fugacious. Aspid. Kze. Polypodium nigrocarpum, Bedd. Fil. S. Ind.

 ebeneous, deciduously scaly ; fr. 2 ft. 1., 6-8 in. br. ; pinnce distant, erecto- 

 patent, flexuose, lanceolate, 4-6 in. 1., 2 in. br. ; pinnl. distant, lanceolate, cut 

 down to the rachis below into subquadrangular toothed lobes ^ in. br. ; texture 

 subcoriaceous ; rachises and both sides naked ; veinlets of the lobes forked ; sori 

 in rows close to the midribs of the pinnules. Lastrea, Moore. 



Hab. Nepaul, Wallich. This seems a well-marked plant, perhaps nearest on the 

 whole to N. sparsum. 



133. N. (Last.) opposition, Hk. ; st. 1 ft. or more 1., densely clothed with 

 spreading, linear, dark-brown scales ; fr. 1^-2 ft. ]., 12-18 in. br., subdeltoid ; 

 lower pinnce 6-9 in. 1., 3-4 in. br. ; pinnl. close, linear-lanceolate, cut down 

 nearly to the rachis into close, entire, slightly falcate, linear-oblong lobes in. 

 ]>r. ; 'texture herbaceous ; rachises scaly ; veinlets of the lobes simple ; sori small, 

 submarginal ; invol. thin. Hk. Sp. 4. p. 136. t. 266. 



Hab. Mauritius and Bourbon. This closely resembles the next in cutting, but the 

 spreading scales of the rachis are 5 in. 1., and the sori are more regular and nearer 



the edge. 



134. N. (Last.) intermedium, Baker ; st. 1-2 ft. 1., stout, erect, densely clothed 

 at the base with long bright-brown silky fibrils ; fr. 2-3 ft. 1., 12-18 in. br., 

 subdeltoid ; lower pinnce lanceolate, often 1 ft. 1., 4-5 in. br. ; pinnl. close, 

 lanceolate, with distinct, oblong-lanceolate segm. with ligulate subentire lobes 

 about 1 lin. br. ; texture herbaceous, firm ; rachises slightly fibrillose like the 

 stem ; under surface naked or slightly scaly on the midribs ; sori small, copious,
