48. POLYPODIUM, EUPOLYPODTUM. 333 



Hab. Brazil, Burchell, 1977, 2020. This comes near some of the forms of P. pect inatum, 

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



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

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

 close blunt horizontal entire or slightly-toothed pinna l|-3 lin. br., the lower 

 ones much reduced ; texture papyraceo-herbaceous ; colour deep-green ; ractm 

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

 sori in lonj? rows. HJc. Sp. 4. p. 203. G. F. t. 10. P. lomariseforme, Kze. Hk. 

 L c. /3, P. Schkuhrii, Raddi ; fr. smaller, nearly naked, the veins black 

 J3fc^.4.>.204. 



Hab. Mexico and W. Indies to Peru and Brazil ; common. Similar in habit to the two 

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

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

 branch. 



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

 brown ; st. 3-6 in. L, wiry, black, scarcely at all villose ; fr. 6-9 in. 1., 3 in. br., 

 lanceolate, cut down to "the rachis into close bluntish slightly crenate pinnae 

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

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

 forked ; sori submarginal. Klotzsch, Linn. 20. jo." 380. P. Spixianum, Mart. 



Hab. Columbia, Moritz, 335, Lindig ; Brazil, Burchell, 2268. 



181. P. Abitaguce, Hk. ; rhizome clothed with linear bright-ferruginous 

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

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

 pinnw J in. br., dilated at the base, the lowest not reduced ; texture coriaceous j 

 rachis 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 

 finely-villose stem and surface and medial sori. The two are much more coriaceous than 

 pectinatum, with the veins hidden, and lower pinnae 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 rachis into close bluntish nearly 

 horizontal obscurely undulated pinnce J-f in. br. ; texture papyraceo-herba- 

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

 two long rows. #. Sp. 4. p. 202. 



Hab. Venezuela, Moritz, 217, Fendler, Steetz. 



183. P. ellipsoideum, Fee ; rhizome stout, wide-creeping, the scales long, 

 spreading, lanceolate-acuminate, dark-brown ; st. 3-4 in. 1., slender, erect ; fr. 

 6-9 in. 1., l|-2 in. br., cut down to the rachis into close spreading pinnce If -2 

 lin. br., which are slightly dilated at the base and then narrowed gradually to 

 an acute point ; texture thin ; rachis and both sides finely villose ; veinlets 

 pellucid, the lower ones subpinnate ; sori oblong, in a close row near the edge. 



Hab. Mexico, Schqffher. 



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. L, 3-4 in. br., cut down to the rachis into numerous entire horizontal 

 pinnce 2 lin. br., with their own breadth between them ; texture papyraceo- 

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

 12 or more on each side, Hk. Sp. 4. p. 207.
