1. CYATHEA. 27 



2'/j m. long, the rachises castaneous, minutely tuberculate, glabrescent, 

 provided with a prominent gland near the bases of each pinna. Pinnae 

 sessile, the largest 40 cm. long, the rachis clothed above with brown hairs 

 intermixed with deciduous, long-filiform scales. Pinnulae sessile, the largest 

 5 cm. long, cut down to the costa in the lower part. Tertiary segments 

 obtuse, the lower free, 7 mm. long, hardly 2 mm. broad, serrate in the 

 upper part. Texture coriaceous; costae beneath clothed with brown, 

 lanceolate, acuminate scales, especiahy towards the base, otherwise scaly 

 with minute, ovate or bullate squamulae; veins 6 — 7 on a side, mostly 

 forked. Sori costular ; indusium soon cup-shaped with an irregular opening, 

 at length often cleft down nearly or quite to the base.

(17) C Kortlialsii, Mett. 



Fronds 3-pinnatifid, the main rachis hardly nodulose, yellowish-reddish, 

 shortly ferrugineo-tomentose above, the secondary ones smooth, ferrugineo- 

 hirsute above, clothed beneath with a few flaccid, scattered scales. Pinnae 

 30—45 cm. long, subsessile, elongate-oblong. Pinnulae sessile, elongate- 

 oblong, 4 — 8 cm. long, l'/4 — 1^/., cm. broad, shortly acuminate with a blunt 

 point, deeply pinnatifid. Lobes elongate-oblong, approximate, subfalcate, 

 subentire, obtuse, narrow, confluent at the base. Texture subchartaceous, 

 firm; surfaces naked; upper surface dark, lower paler; costae ferrugineo- 

 hirsute above, -sparingly bullato-paleaceous beneath, the scales mixed with 

 a few long hairs conf Copel. ~ ; veins 6 — 8 on a side, the lower forked. 

 Sori more or less copious, costular, chiefly -in the lower part of the lobes ; 

 indusium firmly membranaceous, at first breaking at the top, falling away 

 in fragments, . often with a persistent base resembling the indusium of 

 Hemitelia.

(18) C crenulata, m. 



Stipes not spiny but not rarely minutely muriculato-asperulous, 

 deciduously scaly. Fronds 3-pinnatifld or sub-3-tripinnate, the main and 

 secondary rachises above ferrugineo-tomentose, beneath deciduously pale- 

 ferrugineo-furfiiraceous, soon naked, smooth or hardly asperulous. Pinnae 

 subsessile or short-stalked, elongate-oblong, to .50 cm. long, to 20 cm. broad, 

 acuminate. Pinnulae lanceolate-oblong, 5 — 10 cm. long, to 2 cm. broad, 

 acuminate, deeply pinnatifid below the crenate or crenulate apex. Segments
