6. T./wrca^fi, Willd. ; caudex subrepent densely tomen- 

 toso-radiculose, fronds csespitose subsessile 4-15 inches long 

 firm membranaceous (rarely simple and linear-lanceolate) 

 cuneato-obovate in circumscription dotted beneath with co- 

 pious but not crowded peltate brown scales superior half or 

 more subdichotomously pinnatifid with 3-9 or more linear 

 finely acuminated segments 3-8 inches long from 3 lines to 

 I an inch in their greatest diameter entire long-decurrent 

 at the base so as scarcely to leave any stipes, costate, costte 

 prominent beneath, veins erecto-patent obscure in the larger 

 specimens simple or forked here and there anastomosing, in 

 the smaller and narrower ones more or less but never copi- 

 ously anastomosing generally forming solitary large oblong 

 areoles with no free veinlets, sori chiefly upon the (sometimes 

 contracted) segments marginal linear continuous or more 

 or less interrupted. — Willd. Sp. PL v. p. 136. Hook, and

 dioides ; sori interrupted, and so regular and at such short 

 distances as to resemble those of Polypodiuni. 



Hab. Tropical America: West Indies, frequent; Cuba, C. Wright, n. 980; 

 Trinidad, Purdie, n. 20 ; Guiana, abundant, Rich. Schomburgk, n. 243 (Taen.

 n. 655, Purdie; Brazil, Spruce, n. 2370.— Var. poli/podioides. Ecuador, near 

 Guayaquil, Jameson, Spruce, n. 6576, on Theobroma Cacao.— Tfr. Greville and 

 mvself little imagined that in our Tcenitis furcata given our in Ic. Fil. we were pub- 

 lishing a new species, as Fee and Moore now consider it to be ; the latter, indeed, 

 refers it to another genus, but 1 think if these authors had the opportunity of con- 

 sulting extensive suites of specimens, tlicy would find all intermediate grades of 

 venation, free and anastomosing, undoubtedly ou the same individual specimen.
