veinlets forked, sparsely hairy beneath; sori inframedial, exindusiate. 

 Beddome calls this "By far the most beautiful of all tree ferns." 

 India, Ceylon, Java. 



36. Cyathea strigosa Christ. 



Stipe 45 cm long; frond G5 cm long, 40 cm broad, coriaceous; axes 

 aculeate, orange-red, hairy and bearing pale, bullate scales; pinnae 10 to 

 12, 20 cm long, the lowest not reduced, sessile ; pinnules sessile, acute but 

 not caudate, cut almost to the casta; segments long-triangular, falcate, 

 entire, the margin involute, usually glabrous above ; veinlets densely scaly 

 and hairy beneath, forked ; sori small, costular, indusium white-scarious. 

 Decidedly alpine in aspect. 



Celebes (Wawa Karaeng, from 2,000 m alt. to the summit). 



37. Cyathea zollingeriana Mett. 



Frond coriaceous, dark-green above, pale beneath ; rachises above ferru- 

 gineous-hirsute and paleaceous; the secondary rachises and costae beset 

 beneath with fugacious, lanceolate, acuminate scales and persistent, 

 smaller, ovate, denticulate ones; stipe and rachis dark-purple, nodulose 

 beneath, rachis above the base of each pinna bearing a prominent 

 "aerophore;" pinnules 6 cm long, 14 mm wide; segments close, connected 

 by a narrow wing, elongate-oblong, serrate throughout, obtuse, subfalcate, 

 with forked veinlets, and one costular sorus on each side at the base; 

 indusium rigid-membranaeeous, ferrugineous-fuscous, at first opening 

 by a small pore, then irregularly torn. 



Java. 



38. Cyathea rufo-pannosa Christ. 



Trunk 2 m high, 4 cm in diameter, the upper part covered by a matting 

 of roots, leaf-scars about 13 mm wide and 15 to 22 mm long; bases of 

 stipes and crown of trunk clothed with appressed, narrow, scarious, opaque, 

 chestnut scales, 13 to 14 mm long; stipe up to 55 cm long, red-brown, 

 bearing fine, sharp, black prickles, and covered with a fine rufous scurf, 

 as is the rachis; frond very variable in size, up to 150 cm long and GO cm 

 or more broad, the lowest pinnae reduced and deflexed ; middle pinnae up 

 to 37 cm long, 11 cm broad, sessile, the rachis very hairy above, beneath 

 densely clothed with fine, pale, squarrose scales like those on the main 

 axis, and sparse, entire, linear-lanceolate, chestnut ones 4 mm long; 

 pinnules sessile, 55 mm long, 13 mm wide at the base, acute, cut to the 

 costae for half their length; costae clothed above with brown hairs, and 

 beneath with copious pale-brown, lanceolate scales 1.5 to 2 mm long; seg- 

 ments (or secondary pinnules) hardly 2 mm wide, 5 mm long, obtuse, 

 adnate (except usually the lowest), serrulate toward the apex, glabrous 

 above with salient, wavy costule, beneath bearing pale, bullate scales, and 

 sometimes such as clothe the costa; veinlets about 8 on a side, forked;
