 the paleaceous stipes ana rachis, which is perhaps at best a fugacious character.

Hal). Venezuela : Merida, Moritz, n. 409. Tovar, Fendler, n. 472. — I possess 

 a noble frond of this Fern from Mr. C. Wright, named by Mr. Eaton ; it is 3 feet 

 long, exclusive of the stipes ; many of the pinnse are 6 inches long, and many 

 are opposite, and the base of the frond is much attenuated below, in consequence 

 of the gradual reduction of several of the lowest pairs of pinn:e. It possesses, 

 however, no very striking characteristic mark, except it be in the " pinna; infra

 very manifest in my specimen ; perhaps because, in the dried and pressed statg
