 Hosttnann,7i.206. — One of the most splendid of this beautiful genus. 

 Roots coarse, fibrous, descending:. C'aude.K apparently none. Fronds 4 

 inches to li foot hit;h. Rachis sometimes running out far beyond the 

 frond and proliferous, rooting. Pinna; 2 — (> inches long, from 4 to 20, ter- 

 minal one often very much elongated, sometimes tlie lateral ones are whol- 

 ly abortive or wanting, and then the ]dant becomes T. Vittaria, DeCand. 

 and Hook., /. c, which 1 now agree with Splitgerher in considering a re- 

 markable state of T.Jlorihundum. It is a foot and a half and more long, 

 quite a simple frond, and, at first sight, very unlike the ordinary stale of 

 the plant. Veining close, forked ; veins when seen under a leus united by 

 slender transverse ones. 



44. T. pennafnm, Kaulf ; "sterile fronds oblong pinnate 

 subsessile, pinnje oblong obtuse denticulate subimbricate, fer- 

 tile fronds rhomboid pinnated on a long stipes, pinna; linear 

 lowest ones obtuse the margins sjnnuloso-deuticulate, uj)per 

 pinnaj confluent, involucres exserted." Kan If. En. Fil. p.

Hab. Cayenne, {KauJfnss). — I can see nothing in the author's characters 

 and description to justify the separation of this from T. florihnndum, and 

 yet so accurate a man as" Kaulfuss would hardly speak of it as " satis di- 

 versa," unless there were some really distinguishing marks.
