﻿22 1. CYATHEA. 



main rachis yellowish, punctato-muricate, tomentose above. Pinnae to 60 c.M. 

 long, on stalks 2 — 4 c.M. long. Pinnulae 1% — 10 c.M. long, 1% — 2 c.M. 

 broad, sessile, oblong-lanceolate, can da to-acuminate, the point serrate, the edge 

 deeply pinnatifid nearly to the costa. Lobes linear-oblong, approximate, subfalcate, 

 the margin serrate and rather recurved. Texture coriaceous; colour black- 

 green, paler beneath ; rachises and costae ± tomentose above ; costae and costulae 

 furfuraceous beneath, the hairs and scales brownish; veins 8 — 12 on each 

 side of the costulae, mostly forked. Sori 4 — 9 on each side, close to the 

 costulae which they conceal; indusium firm, persistent, becoming subglobose, 

 the mouth a little contracted, entire.

* (20) C. runcnsis, ». A. v>. n. 



Fronds large, 3-pinnatifid ; main rachis setose above like the secondary ones 

 and the costae; the setae subulate, ± adpressed, reddish-brown. Pinnae + 

 55 c.M. long, 22—25 c.M. broad. Pinnulae sessile, spreading, 2 — 2^2 c.M. 

 broad at the base, the apex acuminate, toothed or crenate, the edge cut + 

 */g-way down to the costa into numerous (+ 15), oblong, bluntish, subfalcate 

 lobes with a narrow space between them, the margin crenate, recurved, the lowest 

 anterior lobes spreading, 5 m.M. broad, the lowest posterior ± erecto-patent; 

 lowest pinnulae not the longest. Texture coriaceous ; under surface paler than 

 the upper one; veins distinct, ± 8 on each side of the costulae, the lower 

 1 — 3 forked. Sori medial on the veins, occupying nearly all the veins, except 

 the highest ones, filling up the whole space between the costulae and the 

 margin; indusium thin, hyaline, breaking down irregularly, the lower part 

 persistent.

Stipes strong; the scales copious, lanceolate, brown, crisped. Fronds 

 oblong-lanceolate, 3-pinnatifid, ± 60 c.M. long, 20—30 c.M. broad; main rachis 

 paleaceous. Pinnae sessile, oblong-lanceolate, + 5 c.M. broad, the loAvest not 

 reduced. Pinnulae immerous, close, lanceolate, sessile, the lower ones deeply 

 pinnatifid. Lobes linear-oblong, erecto-patent. Texture subcoriaceous; under 

 surface densely scaly on the costae; veins simple, 4 — 5 on each side of the 

 costulae, erecto-patent. Sori in 1 row on each side of the costae; indusium 

 firm, cupuliform, naked, persistent.
