﻿694 72. CYCLOPHORUS. § 2. niphopsis. 



Rhizome creeping, scaly. Barren fronds linear-oblong, 20—30 c.M. long, 

 3 — 5 c.M. broad, narrowed towards both ends, on stipes to 12'/2 c.M. long; 

 fertile fronds linear-lanceolate, 35 — 65 c.M. long, 2—4 c.M. broad, on stipes 

 to 5 c M. long. Texture coriaceous ; upper surface soon naked, lower densely 

 clothed with soft, brown tomentum ; costa prominent ; main veins slightly 

 prominent; areolae hidden, with the included veinlets simple or forked, free 

 or anastomosing. Sori large, in 2 rows between the main veins, occupying 

 the upper ^U-'-^j-i of the frond, forming 3 — 6 rows on each side of the 

 costa in the broader part of the frond ; capsules mixed with stellate hairs, 

 especially when young. — Baker and Diels placed this species in Niphobolus, 

 but the specimens from Java (Leg. de Vi-iese) and Sumatra (Leg. Korthals) 

 determined by Burck (as P. dislichocarpum, Melt.) and a plant sent from 

 Malacca and cultivated in the Buitenzorg gardens have the venation decidedly 

 irregular.

Rhizome slender, wide-trailing, clothed with large, lanceolate, pale-reddish- 

 brown, membranaceous scales. Stipes scattered, naked, pale-brown, 5 — 8 c.M. 

 long. Fronds lanceolate, entire, 20 — 30 c.M. long, 2 — 2Y2 c.M. broad above 

 the middle, acute, narrowed gradually towards the base. Texture coriaceous; 

 upper surface naked, lower whitish, matted with loose, soft, reddish-brown 

 tomentum; main veins obscure, erecto-patent, enclosing copious minute areo- 

 lae; free veinlets simple or forked. Sori large, round, superficial, densely 

 pilose, in erecto-patent rows of 5 — 6 between the midrib and margin, 

 filling up the whole of the upper part of the frond and mixed with copious 

 soft, brown stellate hairs. — Near C. distichocarpus, C. Chr.

Rhizome wide-creeping, string-shaped, branched, black-purple, densely clothed 

 with subulate, aristate, scariose, squarrose, glistering-while scales. Stipes dis-

 Fronds linear-lanceolate, 18 — 40 c.M. long, 2 — 2V2 c.M. broad, the apex elon-
