NEPHRODIUM, § EUNEPHKODIl'M. 83 



opposite pinnnc, that, but for the constant presence of distinct invohicres in the 

 species before us, and the Large sori quite confined to the margin of the lobes, one 

 would say the two were identical. The position of the sori here bears nearly the 

 same relation to the following species as our N. terminans does to N.propinquum. 



36. N. (Eunephrodium) brachyodon, Hook. ; " frond ovate- 

 oblong subglabrous glossy above pinnated, pinnae subopposite 

 shortly petiolate elongato-laneeolate acuminate ])innatitid witli 

 a deep membranaceous line at the sinuses (sinibus alte mem- 

 branaceis), costa glabrous sulcated flexuose towards the apex, 

 with a gland at the base, the teeth or laciniee very short sub- 

 falcate margined obtuse, sori uniseriate, rachis puberulous," 

 Kze. ; to which may be added from my own specimens, cau- 

 dex short stout erect knotted, stipites 1-2 feet long glabrous, 

 frond I5-2 feet, pinna3 almost always opposite large six to 

 eleven pairs and a terminal ])etiolated one 6-8 inches long, 

 generally subfalcate often 2 inches broad, segments rather 

 variable in length, sometimes the two lowest pairs of veinlets 

 unite below the membranaceous sinus sometimes two or three 

 pairs approximate and run parallel and scarcely unite, sori 

 equidistant between the margin and the costule (never mar- 

 ginal), involucre reniformi-cordate soon deciduous or want-

Hab. Tropical America : Pampayaco, Peru, Pceppig ; Coast of Ecuador, and 

 Panama, various parts of the coast, Seemann, Lieut. Wood; foot of Chimborazo, 

 Jameson, Spruce, n. 5720; Galapagos, Lieut. Wood; St. Vincent, Rev. L. Guild- 

 ing ; Dominica, Dr. Imray. — Mr. Smith's figure of Phlegopteris Seemanni well 

 represents one form of this plant, and which Mettenius, I think, correctly refers 

 to Polypod. brachyodus, Kze. ; but in one of Dr. Seemann's specimens from the 

 Bay of Cliico, in my herbarium, and on one from Mr. Spruce, it is clearly to be 

 seen that it is an indusiate Fern, and, as I have already observed, nearly allied to 

 Nephrodium Fendleri, next to which I place it. 



37- N. (Eunephrodium) stijmlare, Moore; "fronds pin- 

 nate, pinnae pinnatifid entire, stipules pinnatifid acuminate, 

 sori approximate." — Willd. Sp. PL v. p. 239. Filix ad alas 

 foliosa, Plum. Fit. xviii. /. 23. 



Ilab. Martinique, Plumier. — A very large Fern, Gfeet high, and a very remark- 

 able one, if there be no exaggeration in the figure ; for each pinna (many of them 

 a foot long) bears a lesser one, 1-2 inches long, from its superior base. It is 

 probably a monstrosity of some well-known species.
