rizontally patent rnther distant linear-subuiate l)ut obtuse 

 entire subsinuate wlien fertile, sori rather distant submarginal 

 but the two series almost meet at the costule and project at 

 the margin and are alpnost entirely concealed by the scales, 

 rachis very furfuraceous. (Tab. CCLXXXVI. B.) 



Hab. Guatemala, G. U. Skinner, Esq. — A very elegant and distinct species, 

 the slenderest of the group, very furfuraceous with beautiful scales.

 long creeping filiform rooting with copious tomentose fibres, 

 stipites remote distant i-1 inch long scarcely paleaceous, 

 fronds 1-1^ inch long \ an inch wide coriaceo-membranace- 

 ous oblong-acuminate paleaceous with scattered subovate 

 appressed toothed deciduous scales pinnated, pinnse 11-15 

 distant oblong cuneato-attenuate at the base inciso-subpin-

 veins forked once or twice, sori few large near the apex 

 of the segment terminal on a veinlet. — Schlecht. in Linntjea,

 Harris, F. Midler, Linden, n. 27 and 159, Galeotti, n. G327. — A most distinct but 

 small species, with long, filiform, entangled, rooting caudices. 



119. P. (Eupolypodium) macrocarpum, Pr. ; caudex stout 

 for the size of the plant creeping copiously rooting clothed 

 above with ferruginous scales, stipites remote tawny 2-4 

 inches long rigid scabrous with small scales, fronds 2-4 

 inches long \ an inch to an inch wide thick and fleshy very 

 firm and coriaceous when dry, subovate or oblong bluntly 

 acuminate naked above copiously scaly beneath with ovate acu- 

 minate peltate reticulated appressed scales angulato-dentate at 

 the margin deeply beyond the middle pinnatifid, segments 

 patent 5-21 oblong oljtuse more or less approximate sub- 

 serrate, costules immersed represented by a depressed line 

 or furrow, veins altogether immersed and invisible, sori large 

 copious occupying most of the segments in two series. —
