Hab. Brazil, Burckdl, 1977, 2020.— This comes near some of the fonns of P. peclinalum, 

 bot the scales are different, and the lower pinnae not reduced. 



179. P. pectinatum, L. ; rlasome stout, fibrillose ; si. rigid, erect, 2-6 in. 1., 

 naked or finely villose ; fr. 1-2 ft. 1., 2-6 in. br., cut down to the raehis into 

 close blunt horizontal entire or slightly-toothed pinncB lJ-3 lin. br., the lower 

 ones much reduced ; tenure papyraceo-herbaceons ; colour deep-green ; raehis 

 and both sides naked or finely villose ; veinlets pellucid, once or twice forked ; 

 sori in long rows".— SI. Sp. 4. p. 203. (?. F. t. 10. P. lomariiEforme, Kze. Hi. 

 I. e. 



Hab. Mexico and W. Indies to Pern and Bra2!l ; common. — Similar in habit to the two 

 last, but larger, with the veinlets pellucid in the living, and conseouently inconspicuous in 

 the dried plant, usually twice forked, and producing the soms from the tip of the lowest 

 branch. P. Wageneri, Mett., is a form with anastomosing veins. 



180. P. meridense, Klotzsch ; rhizome creeping, the scales fibriUose, dark- 

 brown ; St. 3-6 in. 1., wiry, black, scarcely at all pilose ; fr. 6-9 in. 1., 3 in. br., 

 lanceolate, cut down to the raehis into close bluntish riightly crenate piniice 

 2 Un. br., which are dilated at the base, the lowest not reduced ; texture 

 coriaceous ; raehis villose ; both surfaces nearly naked ; veins hidden, once 

 forked; £ori snbmarginal. — Klotzsch, Linn. W. p. 380. P. SpiKianum, Mart. 



Hab. Columbia, Maritz, 335, JUndig ; BrazD, BurcluU, 2288. 



181. P. Abitoffuw, Hk. ; rhizome clothed with linear bright-fenrnginous 

 scales ; St. 6-9 in. ]., firm, erect, ebeneous, finely villose ; fr. 1 ft. or more 1., 

 3-4 in. br., cut down to the raehis into obscurely undulated subacute horizontal 

 pinn<B J in. br., dilated at the base, the lowest not reduced ; texture coriaceous ; 

 raehis and both sides finely villose ; veins immersed, once forked ; sori in two 

 rows midway between the edge and midrib. — Hk. Sp. 4. p. 206. 



Hab. Andes of Ecuador, Spruce, 5281. — ^Very near the last, from which it differs by its 

 finelj-villose stem and surface and medial sori. The two are much more coriaceons than 

 peciinaiuTHf with the veins hidden, and lower pinn£e not reduced. 



182. P. Moritzianum, Link ; rhizome stout, creeping ; scales lanceolate-subu- 

 late, ferruginous ; St. 4^6 in. 1., naked, glossy, erect _; fr. erect, 12-18 in. 1., 3-4 

 in. br., cut down nearly or quite to the raehis into close bluntish' nearly 

 horizontal obscurely undulated pinnce ^§ in. br. ; texture papyraceo-herba- 

 ceous ; raehis and both surfaces naked ; veinlets distinct, once forked ; sori in 

 two long rows. — Sk. Sp. 4. p. 202. 



Hab. Venezuela, Moritz, 217, Fendler, Steelz. 



183. P. chnoopJiorum, Kze. ; rhizome stout, creeping ; scaks small, few, linear ; 

 St. 4-6 in., firm, erect, grey, villose ; fr. oblong-lanceolate, 9-15 in. 1., 3-4 in. br., 

 cut down to raehis into figulate, bluntish, entire pinnce 2-3 lin. br., the lowest 

 shorter, deflexed ; texture membranous ; surfaces and weak raehis villose ; veins 

 twice forked, 10-15-jugate, slender, indistinct ; sori medial, superficial, at end of 

 anterior branches.— Si. Sp. 4. p. 208. P. sublanosnm, Hk. Sp. 4. p. 221. 



Hab. South Brazil, Gardner, 122, ibc. 



184. P. Martensii, Mett. ; rhizome stout, wide-creeping, clothed with large 

 bright-ferruginous lanceolate membranous scales ; st. 1-2 in 1., firm^ erect; fr. 

 8-12 in. 1., 3-4 in. br., cut down to the raehis into numerous entire horizontal 

 pinncB 2 fin. br., with their own breadth between them ; texture papyraceo- 

 herbaceous ; raehis and both sides finely villose ; veins subpinnate ; sori medial, 

 12 or more on each side. — Hk. Sp. 4t. p. '2ffJ. P. callolepis, Fee.
