Niphoholus. —Yvhizome widecreeping, slender, the scales 

 whitish, at length ferrugineous, dark-brown at the centre, thin, 

 siibulate-ovate, soon erose and obliterate. Barren fronds short- 

 stalked or subsessile, in 2 opposite rows, oblong, 1 — 2 cm. long, 

 i/g- 1 cm. broad, the apex roimded, the base caneate, rounded 

 or cordate. Texture very thick: upper surface soon naked, lower 

 clothed with dense but adpressed, more or less deciduous, mode- 

 rately woolly, brown tomentum; costa somewhat prominent 

 beneath, rather sulcate above. Fertile fronds linear or linear- 

 lanceolate, 4—15 cm. long, 1—5 mm. broad, subinduplicato- 

 canaliculate, blunt at the apex, narrowed at the base, soon naked 

 above, densely clothed beneath with subadpressed, ferrugineous 

 tomentum. Sori rather large, in 1 — 3 irregular rows on each 

 side of the costa, at length prominent and contiguous, when 

 young immersed in the substance of the frond, each cavity closed 

 by a small, roundish, lid-like, introrse, deciduous latéral outgrowth 

 of leaf-tissue, which is covered by a large, globose t^uft consisting 

 of densely crowded, very long-stalked, ferrugineous stellate hairs, 

 the tufts ca 2 — 5 mm. each way.

Acrophorus, at least in Malayan material, is not distinguish- 

 ed by any constant character from Cystopteris, which may have 

 the sori as well terminal as dorsal on, the veins or veinlets (See 

 Christ, Farnkr. d. Erde, p. 280, 1. U fr. b.) 



Most of the Malayan spécimens occurring in the Buitenzorg 

 Herbarium have the sori nearly exclusively dorsal and only 

 occasionally terminal or subterminal on the veins or veinlets 

 and in the spécimens received from British India (Himalaya) it is 

 just the contrary. 



The indusium is suborbicular, fornicate, fastened by a broad 

 base under the sorus (i. e. the indusium is attached to the re-
