9. CASTANOPSIS MEGACARPA, Gamble in Kew Bull. 180 (1914). 
A large tree reaching 12—18 m. in height and 60—90 cm. in diam. 
of stem; branches spreading, pendulous; branchlets moderately 
stout with dark brown bark and very small lenticels; uppermost 
ones minutely tawny velvety ; leaf-buds ovoid, the scales lanceolate, 
tawny-velvety. Leaves coriaceous; oblong or elliptic-oblong or 
elliptic, shortly cuspidate-acuminate at apex, acute or rounded 
sometimes unequally at base; upper surface glabrous, olive-brown 
when dry, shining, lower minutely fulvous- or cinnamomeous-pubes- 
cent; margin entire, recurved; variable in size from 8—14 cm. long 
by 3—4 cm. broad to 16—24 cm. long by 5—9 cm. broad; midrib 
moderately stout, raised on both surfaces; main nerves 12—16 
pairs, parallel, slightly raised above, prominent beneath, very 
slightly curved to close to the margin and then abruptly curved to 
fade away closely along it; transverse nervules many, subparallel, 
rather faint, enclosing the obscure areolate reticulation ; petiole 
1°5— 2-5 cm. long, swollen at base. Spzkes slender, up to 20 cm. long, 
in loose terminal or axillary panicles, chiefly ¢, the 2 apparently 
scarce; rhachis slender, angular, furfuraceous. Flowers: 3 in 
clusters of usually 3—5 in the axil of an ovate-acuminate pubescent 
bracteole about 1 mm. long; perianth-lobes 6, nearly free. obovoid, 
villous, about 1 mm. long; stamens 12 with rather short slender 
filaments and small globose anthers; pistillode rather small, very 
villous: 2 not known. Fruits globose, when mature reaching 5—6 
cm. in diam., in rather slender spikes with the rhachis 5 mm. in 
diam.; cupule very thick-walled (1 cm. at the base, 5 mm. in the 
middie) the walls granular, hard ; covered, except an oblong patch 
on the inside, with scattered tubercles forming thick stalks from the 
summit of which radiate simple or staghorn-like branched slender 
subulate spines, usually 1—1‘5 cm. long and minutely stellate- 
pubescent except at the tips, nearly glabrous at length; nut 1, 
closely adherent to the cupule, only the umbo protruded from a 
small orifice; seed ovoid, 2°5 cm. long, 2 cm. in diam. the testa thin 
and closely pubescent ; cotyledons sinuate. C. javanica, Hook. f. in
