﻿1. CTATHEA. 23 



* (22) C jai'anica, jBL, Rac, Flor. Btz., I, 3S. 



Fronds large, 3-pinnatifid ; main rachis unarmed but not rarely rough, 

 paleaceo-tomentosc like the secondary ones. Pinnae to 60 c.M. long, on stalks 

 to 2 c.M. long, linear-lanceolate, acuminate. Pinnulae lanceolate, to I'/j c.M. 

 broad, deeply piniiatifid. Lobes linear, subfalcate, entire or obtuso-crenulate. 

 Texture subcoriaceous; under surface bullato-squamulose on the costae; veins 

 8 — 10 on each side of the costulae, the lower forked. Sori 2—6 on each 

 side of the costulae, the lower divaricating; indusium thin, breaking down 

 irregularly, the base persistent, cupuliform, firmer.

* (23) C. iSMmatrana, Bie., Joum. of Bot., XVIII, 209. 



Fronds large, 3-pinnatifid to subtripinnate; rachises tomentose, especially 

 on the upper side and clothed with long, linear, acuminate, scattered, brown 

 scales, which make the rachises rough when they fall. Pinnae ± 50 c.M. 

 long, with the opposite pinnulae of contiguous pinnae overlapping. Pinnulae 

 numerous^ spreading, + 6 — 8 c.M. long, ± l^/j — 2 c.M. broad, oblong, sud- 

 denly acuminate at the narrow, mostly linear, broadly crenate apex, the point 

 blunt, the edges parallel, cut down nearly to the costa, pinnate at the very 

 base. Segments linear-oblong, + 3 m.M. broad, falcate, blunt, entire or crenate, 

 not conspicuously recurved at the edge, the lowest 1 — 2 free, mostly bluntly 

 toothed; lowest pinnulae not the largest. Texture coriaceous; costae rough- 

 hairy above; upper surface dark, the under one paler, covered with pale, 

 bullate scales on the costae and the lower part of the costules ; veins 8 — 10 on 

 each side, lurked, the higher simple. Sori close to the costules, occupying 

 the lower 1 — 4 veins ; indusium membranaceous, thin, breaking down irregularly. 



Sumatra, Java.

Fronds 5-pinnatilid. Stipes and rachises more or less densely scaly and 

 hairy, the scales to 1 Vj c.M. long, pale-ferrugineous, the hairs crisped, ferru- 

 gineous, joined into groups. Pinnae 27 — 30 c.M. long, imbricate, sessile, oblong, 

 bluntish, slightly narrowed at the base. Pinnulae sessile, close, to 6 c.M. long, 

 to 1 ^2 c.M. broad, bluntish, cut down nearly to the costa into short-acuminate, 

 subfalcate, crenulate to toothed lobes. Texture coriaceous, under surface hairy 

 between the sori ; colour dark-green, paler beneath ; veins inconspicuous, forked 

 at the base. Sori large, 6 — 8 to each lobe; indusium large, flaccid, yellowish, 

 soon deciduous.
