﻿688 72. CYCLOPHORUS. § 1. NIPHOBOLUS. 



phobolus stivticus, Kze, Gies., Niph., 13S; N. fissus, Bedd. (not Bl.), Copel., Po- 

 lypod. Philipp., 115, p. p. 



Rhizome creeping; scales rigid, dark-brown, lanceolate, suberect, acumi- 

 nate, the margin pale and more or less ciliate. Fronds approximate, spathu- 

 late, lanceolate or linear-lanceolate, 15 — 30 c.M. long, 1 — 2 c.M. broad, the 

 apex varying from blunt lo acuminate, the base narrowed very gradually so 

 as to form a winged stipe + 6 c.M. long, the edge entire. Texture coria- 

 ceous; veins hidden; upper surface naked or provided with scattered, adpres- 

 sed, greyish or brownish hairs and small depressed dots, which are covered 

 with deciduous, blackish, calcareous scales; under surface densely tomentose; 

 areolae with 5 — 4 soriferous, excurrent veinlets. Sori rather large, confined 

 to the upper half of the frond, placed in 5 — 8 rows on each side of the 

 costa, immersed among the tomentum, but at length distinct. — Clearly 

 distinguished from C. porosus, Pr. by the rhizome scales.

Rhizome creeping, the scales moderately large, membranaceous, reddish- 

 brown, not closely adpressed, narrow, lanceolate, long-acuminate. Stipes ± 

 1% c.M. long. Fronds 20—50 c.M. long, 2—272 c.M. broad, lanceolate, 

 acuminate, the base narrowed gradually. Texture + coriaceous ; upper sur- 

 face covered with dirty-white, the lower with reddish-brown tomentum ; costa 

 prominent beneath, at length naked, flexuose; main veins slightly visible. Sori 

 superficial, crowded in the upper part of the frond, not reaching the margin 

 and the apex, placed in 6 — 8 rows.

Rhizome wide-creeping, the scales dense, pale-brown or ferrugineous, 

 lanceolate, sometimes crisped, erecto-patent or spreading, peltate and adpres- 

 sed at the base. Stipes 2 — 4 c.M. apart, 4 — 13 c.M. long, covered with white 

 or brown, often deciduous tomentum. Fronds 30 — 80 c.M. long, 1 — 5 c.M. 

 broad, narrowed towards both ends, the edge entire, + recurved. Texture 

 very coriaceous, upper surface at length naked, lower densely clothed with 

 white or brownish tomentum; costa less densely tomentose, like the stipe;
