POLYPOniUM, § EUPOLYPODIUM. 173 



costa slender zigzag, veins simple uppermost ones bearing 

 globose terminal sori iTiternicdiate l)et\veen the costa and the 

 margin, — Hook. 2d Cent, of Ferns, t. 10. 



Hab. Near Tarapota, Eastern Peru, Spruce, n. 47-10. — Among tlie smallest of 

 the species of true Polypodium, and a well marked one. 



25. P. (Eupolypodium) conforme. Brack.; "caudex cocspi- 

 tose, stipites short, fronds Hnear-lanceolate obtuse attenuated 

 at the base membranaceous gkibrous slightly rej)and at the 

 margin and as well as on the costa setose, veins forked, sori 

 biserial approximate plane rounded arranged near the costa, 

 sporangia echinate." — Brack. Fil. U. Si. Expl. Exp. p. 4. /.

Hab. Ovalau, Fiji Islands, on rocks and trees, alt. 2000 feet, Brachenridqe. — 

 " This differs from P. subspatfndatum by the plane sori and their proximity to 

 the costa ; and from P. Jlookeri, l)y the niembranaceons, smooth (glabrous) 

 fronds, and very short stipes." — 1 am not in jiossession of sufficiently good speci- 

 mens to form a decided opinion respecting this species, and P.suhspailndatum, 

 Brack. 1 fear that two si)ecies, or sujjposcd species, are mixed in the P. Ilookeri, 

 Brack., the Malayan Island one, and that from the Sandwich Islands ; and I have 

 intimated that what 1 have from Mr. Eaton, as P. conforme, of Mr. Brackenridge, 

 probably includes two species. 



26. P. (Eupolypodium) subspat hula f. urn, Brack.; "caudex 

 csespitose, fronds few, sterile ones spathulate sti])itate entire 

 coriaceous glal)rous, fertile ones linear-lanceolate attenuate 

 at the l^ase, the margin and stij)es sparingly setose, veins 

 forked, sori biserial distant subimmersed, nearly oval, sporan- 

 gia echinate."- Brack. Fil. U. St. Expl. E.ip. p. 8. /. 1 {Imt all 

 the sori are represented fjlobose) . 



Hab. Tahiti, Society Islands, on trees, Brackenridge. — "Fronds few and very 

 dissimilar in form ; sterile ones, including the short stipes, 1-U inch long, spa- 

 thulate in form, and destitute of setae; the fertile, 4-5 inches in length, which, 

 with the margin of the fiond, is sparsely beset with short and brown sct;e. 

 Veins slender and forked, indistinctly visible on the upper side. The sjjathulate 

 sterile fronds, and the fertile ones, with partially immersed sori, eijuidistant Ijc- 

 tween the costa and margin, readily distinguish this from P. Ilookeri." I possess 

 two specimens under this name ; but one of those of P. conforme, from Mr. Eaton, 

 sufficiently accords with the fertile frond above figured. 



27. P. (Eupolypodium) chrysolepis, Hook. ; caudex very 

 long creeping flexuose paleaceous with patent squaniose fer- 

 ruginous subulate scales, stipites distant 1-2 iuclics long 

 very scaly, fronds 2-S inches long h an inch wide subcoria- 

 ceous lanceolate obtuse entire tapering gradually below into 

 the stipes pale beneath everywhere clothed with ovate pel- 

 tate long-acuininate aureo-nitent scales, veins lather obscure 

 once or rarely twice forked free, sori large terminating a
