COPELAND. 
44. Cyathea oinops Hassk. 
Trunk reaching a height of 12 m, 12 to 15 cm thick; stipe 50 cm 
long, rough, scaly at the base, elsewhere like the rachis, chestnut, clothed 
with a dense, stellate, wine-colored tomentum, the secondary rachises 
and costae bearing this tomentum and also shining, rust-colored scales ; 
frond 140 cm long, 70 cm broad, acute at both ends, tripinnate; pinnae 
oblong, acute; pinnules linear-oblong, very acuminate; secondary pinnules 
linear-oblong, acute, deeply crenate-serrate, bullate, rigid ; veinlets forked, 
sometimes twice; sori in the forks, 12 to 16 to a segment, rust-brown, 
large, finally confluent and covering all but the apex of the segment; 
indusium very thin, soon bifid, then lacerate and vanishing. 
Java, at altitudes above 2,300 m. 
45. Cyathea javanica Blume. 
Trunk 10 m high; frond 190 cm long, 120 cm broad; rachises rufescent, 
glabrous or tomentose above, unarmed but the primary rachis rough with 
minute bristles, secondary rachises paleaceous-tomentose beneath; pinnae 
stalked; pinnules lanceolate, acuminate, deeply pinnatifid, costae bullate- 
scaly beneath at base; segments linear-subfalcate, obtusely crenulate or 
entire; veinlets about 8 on a side, mostly forked; sori few, the lowest 
medial, the upper ones costular; indusium thin, evanescent except for 
a saucer-shaped base. 
Java, Sumatra, commonest below 1,500 m. 
46. Cyathea schizochlamys Baker. 
Fronds ample, tripinnate, firm and subrigid, green on both sides ; rachis 
unarmed, thinly tomentose and clothed with small, linear, acuminate 
scales; pinnse 45 cm long, 12 to 15 cm broad, oblong-lanceolate, their 
rachises densely clothed with small, ovate-lanceolate, cuspidate scales 
which extend to the costae and c-ostules beneath; pinnules lanceolate, 
sessile, 15 to 18 mm broad, narrowed from the middle to the apex, cut 
to the costa into linear, entire or rarely crenulate secondary pinnules 
about 2 mm broad, with a distinct space between them; veinlets 9 or 10 
on a side, forked at the base ; sori costular ; indusium membranous, fragile, 
soon splitting to the base. 
Sumatra (Mount Singalan). 
47. Cyathea sumatrana Baker. 
Frond tripinnate; rachises not spiny, but densely clothed with fer- 
ruginous tomentum and large, linear, acuminate, red-brown, membrana- 
ceous scales; pinnae 45 to 60 cm long, 12 to 15 cm broad, texture firm, 
both surfaces green ; pinnules lanceolate, sessile, 16 to 18 mm broad, cut 
to the costa into ligulate, obtuse secondary pinnules 3 mm broad ; veinlets 
8 to 10 on a side, all but the uppermost once or twice forked ; sori crowded.
