 splendid species. Stipes ;} — C) or (> iuelies; fronds 1 — 12 or M inches louff. 

 Lips of the involucres much divaricated, and sunk, as well as the tube, in 

 the substance of llie frond. Receptacles sometimes very lon<r, i — 5 times 

 the length of the involucres ; sometimes very short, probably broken ?

 irregularly sinuato-dentatc jiellucid at the costid;e and veins 

 which arc hairy beneath bearing sori at the apex, costa) and 

 margined stipes clothed with hispid brown seta;." Kze. in

Hal). Huallaga, Peru, Poeppijj. " Belongs to the same group as T.crix- 

 pum, L., T. cristatum, Kze. (7'. crispum, Sw. and Hook, ct Grev.), T.pi- 

 losuin, Raddi, but most distinct.'' The same author furthcrnotices its si- 

 milarity in texture to T. pihsuvt, but that, in other respects, is very difler- 

 ent. It will however be observed, that those species arc pinnated, whereas 

 T. pelluceits is described as pinnatilid. To judge from a very indilTercnt 

 specimen of the " T. peliucens, Kunzc," in my possession, distributed by 

 Poeppig, this is in reality not distinct from T. crispum, and, like it, it is 

 pinnated below, pinnatiful above. 



49. T. pliiinosKnt, Kze. ; " frond lanceolate linear acumi- 

 nate pinnated, pinnae subadnate oblong-linear attenuated and 

 obtuse at the apex, the sterile margin unequally duplicato- 

 dentate, hairy on each side on the costa and veins upper half 

 soriferous, involucres sunk bidentate, stipes trigonal and as 

 well as tlie rachis rufo-hirsute." Kunze, PL Crypt. Poepp. 

 p. 104. 



Ilab. Pampayaco, Peru, Poeppuj. — This surely is only another slight va- 

 riety of T. crispum. Kunze remarks, " T. crispum, L., Sw., Hedw. Ic., pin- 

 nis iatioribus et brevioribus, involucris uo>j bidenlatis paullo latins distat:" 

 but in our specimens of true T. crispum, the involucres arc bidentate, or, 

 in other words, bilabiate. 



50. T. cr in it urn, Sw. ; fronds rather small tufted slightly 

 glaucous pinnate, pinnaj ovate or oblong sinuate or pinnati- 

 fid, upper ones coadunate sometimes all of them are so (and 

 then the frond becomes pinnatifid), the segments short ob- 

 tuse, the margins rachis and stii)es with long spreading fer- 

 ruginous hairs, involucres few generally solitary from the apex 

 of the pinnae sunk urceolato-cylindrical, the mouth sin-eadiug 

 scarcelv 2-lippcd fringed with long hairs. — Sw. FL IniL Occ.
