172 I'OLYPODIUM, § EUPOLYPODIUM. 



wich Islands as the locality for this species, he may have confounded the two ; and 

 there is a very considerable affinity between them. He gives no description or 

 note further than to sny that P. Hnokeri has the stipites, in many of the speci- 

 mens, thrice the length of what I have figured, which corresponds with P. spfi- 

 gerum, Bl. I retain Brackenridge's name, because the authority for it is expressly 

 our figure and description in the Bot. of Beecliey's Voyage. Possibly the two 

 are varieties of each other. If our figures and remarks shall only contribute to- 

 wards the clearing up some of the difficulties attending the study of this most dif- 

 ficult group, we shall be content. 



21. P. (Eupolypodiutn) congener, Hook.; "fronds stipitate 

 elongato-linear acuminate at both extremities very entire 

 coriaceous veinless subrevolute at the margin glabrous above, 

 beneath and the stipes sul)pubescent, sori rotundato-eUiptical 

 parallel with the costa, caudex repent." — Grammitis conge- 

 ner, Bl. Fil. Jav.p. 108. t. 46./. 3. a and b. 



Ilab. Java, Blume. — Unknown to me. Except that the sori are more globose, 

 the figure exhibits what looks very like a larger form of Blume's Grammitis 

 c(ES2ntom, represented on the same plate (our Polyp, gramineum). 



22. P.? (Eupolypodium) punctatum. Hook.; "fronds 

 linear entire obtuse, the margin nigro-punctate al)ove, sori 

 approximate and parallel with the costa." — Grammitis, 

 Raddi, Fil. Bras. p. 11. t. 22. bis. f. 1. Metten. Polypod. 

 p. 39. 



Hah. Trunks of trees, Brazil, Raddi. — " Roots caspitose, very slender. Fronds 

 \\ inch or more long, al)out a line wide, snbcoriaceous, glabrous. Sori near 

 the apex of the frond. Stipes none." The sori are represented as linear-oblong 

 and quite parallel with the costa. Unknown to me. 



23. P. (Eupolypodium) parieUnum, Kl. ; " fronds thick 

 subspongiose on both sides sparingly rufescenti-pilose linear 

 a little curved shortly attenuated at the apex obtuse (?) long 

 attenuated at the base decurrent into the very short stijies, 

 the margin slightly repand obsoletely costate, veins im- 

 mersed laxly pinnated, the branches hi- rarely tri-furcate 

 not extending to the margin, sori medial convex ferruginous 

 in a simple series approximate to the margin, rhizome repent 

 evanescently paleaceous, stipites crowded." Kze. — Kl. in 

 Linncea, xx. p. 373. Kze. Fil. Schk. Suppl. 2. p. 41./. 17- 

 Metten. Polypod. p. 39. 



llab. Columbia, Moritz,n. 253. — This is unknown tome. 



24. P. (Eupolypodium) Sprucei, Hook. ; dwarf, caudex 

 short subfiliforin, stipites 1-2 lines long densely tufted, 

 fronds scarcely more than an inch long mcmbranaceons sub- 

 pellucid bright-green oblong-subspathulate very obtuse quite 

 entire crinite with long scattered fulvous spreading hairs.
