1. CYATHEA. 29 



(19) C Orientalis, Moore. 



stipes thickened, spinulose and farinoso-tomentose at the base, densely, 

 but deciduousljr, scaly, minutely muriculato-asperous, fulvo-pulverulent, at 

 length giabrescent, beneath fermgineo-castaneous ; main rachis Uke the 

 upper part of the stipe, at least in the lower part, otherwise smooth or 

 nearly so, grooved above, hardly puberulous in the groove; secondary 

 rachises punctulate in the lower part, ferrugineo-velutinous above; costae 

 velutinous above, minutely chaffy beneath. 



(19ffi) C. caudata, Copel. 



Omit this species, it being referred to Hemitelia. 



(196) C. Chrislii, Copel. 



Elmer's No. 10601 differs from Copeland's original diagnosis in having 

 the pubescence of the rachises above intermixed with scattered, dark- 

 coloured, fihform scales, and the costulae beneath copiously buUato- 

 squamulose; No. 114-59 is a plant with reduced foUage. 



(19c?) €. priiiiaosa, Rst., in Fed., Rep., XII, 163. 



Fronds 3-pinnatifid, the rachises ochraceo-tomentose above, naked 

 beneath, Uvid-brown or nearly glaucous. Pinnae 50 cm. long by 15 cm. 

 broad, short-stalked. Pinnulae remote, T'/j cm. long by 1^/4 cm. broad, 

 acuminate, deeply pinnatifid, sessile, slightly decurrent-adnate. Segments 

 subfalcate, nearly a'/j mm. broad, the edge recurved, crenulate. Texture 

 subcoriaceous ; surfaces naked; upper surface oUvaceous, lower paler; 

 costa somewhat tomentose above, scaly beneath, the scales narrowly 

 linear, white, deciduous; costulae naked above, scaly beneath, the scales 

 oval, ferrugineous, subciUate; veins 9 — 10 on a side, forked. Sori costular, 

 on the 2 — 3 lower veins; indusium large, membranaceous, persistent, the 

 mouth truncate. — Rachis unarmed? 



New Ckiinea. 



(20a) C istipulata, Copel., in PhiUpp. Journ., VF, 362. 



Stipes slightly spiny with numerous lanceolate, brown scales at the 

 base; main rachis unarmed, dirty-brown, giabrescent beneath, clothed 

 above with minute, adpressed tomentum. Pinnae spreading, short-stalked, 

 40 cm. long, 12 cm. broad, acute, the rachis castaneous, quadrangular, 

 sparingly furfuraceous beneath. Pinnulae 20 — 25 on a side, horizontal.
