88 FERNS OF BORNEO. 



the texture more rigid, and the ultimate segments smaller and 

 more bullate than in the Australian ty^De, thus approximating to 

 some of the varieties of dicarpa. 



Gleichenia dicJwtoina, Hook. 

 ■"Gleichcnia vestita, Blume, var. paleacea, Baker. A form differing 

 from the Javan type by its lamina very glaucous on the under sur- 

 face and narrower ultimate segments, with rachises densely clothed 

 with spreading or deflexed linear-subulate ferruginous paleae. 



Alsophila (jlahra, Hook.? 



Ahophila latebrosa, Hook. 



69.'" ALSOPmLA BuRBiDGEi, Baker, n. sp. Frond ample, tripin- 

 natifid, moderately firm in texture, green on both sides, paler beneath, 

 the under side strongly ciliated on the midrib of the pinnules, for 

 the rest nearly glabrous, both surfaces and rachises entii-ely free 

 from scales, the latter without prickles, those of the pinnas clothed 

 throughout with fine spreading hairs. Pinnae oblong-lanceolate, 

 a foot or more long. Pinnules sessile, lanceolate, two to two and 

 a half inches long, half an inch broad, cut down to a narrow wing 

 into ligulate subentire obtuse tertiary segments about a line broad. 

 Veins four-to five-jugate, distant, simple or forked. Sori medial. 

 Allied to A. latebrosa, Oldhami and Wcdlacei. 



Hijmenophijllum Blumeanum, Si^reng. 

 '■^'Hi/inenopJujUum Smithii, Hook. The plant so called in Cesati's 

 list proved to be Trichomanes denticulatum, Baker. 

 "^ Hymenophijllum sahi7mfoliuin , Baker. 



Hijmenophyllmn Neesii, Hook. 

 '^Hyynenophyllum formoswn, Brack . 



'^ Hymenophyllum obtusiun, Hook. Gathered lately in New Guinea 

 by Beccari. 



Trichomanes Filicula, Bory. 



Trichomanes pallidum, Blume. 



Trichomanes diyitatum, Sw. Two different forms, one lengthened 

 out with remote branches, the other short, with close branches. 



Trichomanes javanicum, Blume. 



Trichomanes pyxidiferum, Linn. A handsome variety, with 

 unusually compound rather crisped fronds. 



Trichomanes rigidum. Sw. 



Trichomanes maximum, Blume. 

 '^'Trichomanes apiifolium, Presl. 



Trichomanes hispiduliim, Mett. This was only known before 

 fi-om a single sheet of specimens in the Kew herbarium, gathered 

 by Thos. Lobb. 



Trichomanes fieniculaceum , Bory. 



Trichomanes Plnma, Hook. We did not know the definite 

 station of Lobb's specimens, from wliicli this was described and 

 figured by Hooker. Beccari has gathered it near Sarawak. 



Trichomanes trichoj/liyllum, ]\Ioore. With the last, with which 

 I am now inclined to think it will prove to be conspecific. 



Davallia aiujustata, Wall. 



I>arallia lieteraphylla, Smith. 



Darullia pannJa, Wall.
