﻿l60 9. TRICHOMANES. § 2. EUTRICHOMANES. C. ABRODICTYUM. 



Rhizome short-creeping or ascending, densely hirsute. Stipes approximate 

 or subtufted, ^^j^ — T'/^ c.M. long, slender, erect, naked, sparingly hairy at 

 the base. Fronds S — 20 c.M. long, l'/2 — ^ c.M. broad, lanceolate or oblong; 

 main rachis whether or not winged. Pinnae oblong, erecto-patent, the central 

 ones the largest, pinnatifid to a narrowly winged rachis. Pinnulae linear, 

 usually simple, occasionally forked. Ultimate segments '/a — IV2 ^■^^- ^^^^S> 

 ± 'I2 — 1 m.M. broad. Texture rather flaccid, the cells transversally elongated, 

 arranged in obliquely longitudinal (ladder-shaped) rows. Sori 1 — 4 to a 

 pinna, terminal on short lobes; indusium winged, the mouth dilated. — 

 Quite different from all the other species of Trichomanes, which have all + 

 roundish, quadrangular, hexagonal or longitudinally oblong cells. 



Philippines, Moluccas.

Rhizome erect. Stipes tufted, 1 ^2 — IS c.M. long, erect, naked or villose. 

 Fronds 5 — 25 c.M. long, I'/a — 5 c.M. broad, lanceolate-oblong; main rachis 

 hairy. Pinnae short-stalked or sessile with a narrowed base, oblong, unequal- 

 sided, the apex blunt or rounded, the margin finely toothed or ciliate ('), the 

 base obliquely cuneate. Texture firm; veins numerous, close, parallel. Sori 1 — 4 

 to a pinna, placed on the upper edge; indusium free, the mouth truncate or 

 dilate; receptacle much exserted. 



Trop. Asia, Polynesia ^ Australia, Liu-Kiu. 



(') If ciliate, the ciliae consislin|j of ilie often very much produced veins of the pinnae.
