POLYPODIUM, § PHYMATODES. G5 



dervvater scaleless, stipites very slender weak and filiform 

 ^-1 inch long aggregated, fronds 4-6 inches long less than \ 

 of an inch wide carnoso-membranaceous black wlien dry, 

 linear-vittarioid scarcely acuminate subacute entire gradu- 

 ally long-attenuated below into the thread-like stipes, costa 

 prominent beneath and scaly with blackish apjiressed some- 

 what fleshy small ovate scales, venation very distinct when 

 seen between the eye and the light, costulcs none, veins 

 anastomosing so as to form 2-3 series of large parallel but 

 very irregular areoles with no free veinlets, sori in a single 

 but irregular series between the costa and the margin, cap- 

 sules lax. — iFal/. Cut. n. 280. Metten. Polyp. p. 86 [venation). 



Hab. Mount Chappedung, mouth of the river Tenasserim (not " Nepal," as in 

 Mettenius). — A very remarkal)le-looking plant, with the appearance and texture 

 and habit of an aquatic ; the stipites seem to be too weak to sup|)ort the weight of 

 the fronds, thin and light as these are. The venation is well represented by Met- 

 tenius. In a dried state this Fern has much the aspect of short specimens of 

 Zostera marina. 



340. P. (Phymatodes) rhynchoplujllum, Hook. ; caudex 

 creeping slender paleaceous subsquarrose with subulate fer- 

 ruginous scales, stipites scattered slender 1-2 inches long 

 of the sterile frond, 2-4 of the fertile one, fronds firm charta- 

 ceo-membranaceous glossy slightly thickened remotely cre- 

 nate; sterile ones 1-2 inches long elliptical or subovate ob- 

 tuse ; /er/<7e ones 3-6 inches long lanceolate from near the 

 base gradually and long-acuminated, below cuneato-attenu- 

 ated, venation distinct slightly prominent, the costules are 

 connected by transverse veins forming areoles which enclose 

 free veinlets which latter sometimes unite with opposite 

 veins, the sori are mostly confined to the narrow acuminated 

 apex and when mature are very large in a single series on 

 each side the costa. — Hook. Ic. Plant. 955 [or t. 55 of Cent, 

 of Ferns) . 



Ilab. Assam, Mrs. Mack, Griffith. Khasya, Hookpr fil. and Thomson, aXt. 

 4000 feet. — A very pretty and very distinct species, with prominent costa, and 

 distinct costules, and long stipites. 



341. P. (Phymatodes) stenophyllum, Bl. ; caudex creeping 

 paleaceous with glossy subulate pale imbricated ferruginous 

 scales, stipites 1-2 inches long distant, fronds firm-coriaceous 

 very rigid glal)rous polished 4-9 inches long \-h an inch 

 wide llnear-olilong obtuse the margin thickened and subre- 

 flexed broadly crenato-sinuate rarely narrowing upwards but 

 much and gradually attenuated below on the stipes, costa pro-
