﻿71. POLYPODIUM. § 7. SELLI6UEA. 67 7 



Rhizome creeping, woody, the scales dense, linear-lanceolate, brown. Stipes 

 4 — 25 c.M. long, firm, erect, naked, those of the fertile fronds often the longest. 

 Fronds 7 — 30 c.M. long, 1 % — S c.M. broad, the fertile ones not much nar- 

 rower than the barren, lanceolate, acute or acuminate, the edge entire, the base 

 more or less gradually narrowed. Texture coriaceous; surfaces naked, glossy; 

 main veins distinct; veins hidden. Sori immersed, long, linear, solitary between 

 and parallel to the main veins, continuous or slightly interrupted. 



Var. intei'i'iiptum : Sori distinctly interrupted, forming rows of 

 roundish or oblong sori. 



Var. abbreviatum : Fertile fronds much narrowed, subcaudate. 

 Sori roundish or oblong, 1 — 2 between the main veins.

Rhizome woody, creeping, firm, the scales adpressed. Stipes scattered, 

 50 — 40 c.M. long, firm, erect, naked, pale. Fronds 30 — 50 c.M. long, 15 — 25 

 c.M. broad, cut down nearly or quite to the rachis into 4 — 6 linear-oblong 

 or lanceolate, distant, sessile, opposite, acute segments narrowed towards the 

 base, mostly connected by the decurrent, oblique bases, which form a wing 

 to the rachis; longest segments 1 — 4 c.M. broad. Texture herbaceous; rachis 

 and surfaces naked; costal areolae large, with smaller, irregular included ones 

 with free veinlets. Sori linear, oblique, nearer the midribs than the edge.

Stipes + 45 c.M. long, duU-biown, naked. Fronds deltoid, to 30 c M. 

 long, with ± 5 oblong-lanceolate pinnae. Largest pinnae ±15 c.M. long, 

 4^2 — 572 c-M. broad, slightly repand, narrowed gradually at base, the lowest 

 pair distant. Texture membranaceous; surfaces naked; main veins distinct to 

 the edge; areolae copious, small, with free veinlets. Sori abundant, irregular, 

 punctiform or confluent in lines or curves.
