‘1. CasTANopsis MALACCENSIS, Gamble in Kew Bull. 178 (1914). 
A tree; branchlets slender with dark brown bark scarcely at all 
lenticellate ultimate ones tawny-pubescent ; leaf-buds small, ovoid, 
the scales ovate-acute. Leaves thinly coriaceous ; ovate or lanceo- 
late, acuminate and usually mucronate at apex, rounded, often 
unequally at base; upper surface scaly-puberulous when quite 
young, afterwards glabrous, olive-green when dry, lower surface 
minutely tawny-puberulous ; margin entire; 5—10 cm. long, 3—4 
em. broad ; midrib slender, impressed above; main nerves 8—10 
pairs, curved to and along the margin where they disappear in small 
loops; transverse nervules very many and close enclosing the areo- 
late reticulation and with it conspicuous on the upper surface when 
dry; petiole slender, 8—10 mm. long. Spikes and flowers not 
known. Fruits (immature) globose, 1-5—2 cm. in diam., in slender 
axillary spikes up to 10 cm. long, rhachis under 3 mm. in diam. ; 
cupule thin, densely and almost completely covered with tuits of 
spreading straight pubescent needle-like spines 1—1-5 cm. long, the 
Spines rarely branched, geniculate at base and covered except the 
extreme tips with short strigose tawny hairs; nuts usually 3, silky.

Maingay’s specimens in Herb. Calcutt. have the fruits of Pasania sundaica 
in an envelope attached. 
2. CasTanopsits Scortecuinu, Gamble in Kew Bull. 178 (1914). 
A tree; branchlets stout, with grey rough bark, conspicuously 
furfuraceous-puberulous especially the ultimate ones; leaf buds 
ovoid, the scales lanceolate, acuminate, spreading, about 5 mm. 
long. Leaves subcoriaceous; elliptic or slightly oblanceolate, cuspi- 
date-acuminate at apex, acute at base; upper surface glabrous 
except the midrib, olive-brown when dry, lower thickly ferrugin- 
ous-pubescent ; margin entire; S—12 cm. long, 3—5 cm. broad: 
midrib slender, slightly raised and minutely puberulous on the 
upper, more prominent and pubescent ‘on the lower surface; main 
nerves 12—15 pairs, slender and slightly impressed above, little 
curved at first more so close to the margin where they disappear 
along it; transverse nervules fairly numerous, rather irregular, 
reticulation obscure; petiole stout, very short, ferruginous-pubes- 
cent, 5 mm. long. Spikes: g not known: 9 about 15 cm. long 
axillary and lateral on upper branchlets; rhachis grey and fur- 
furaceous-pubescent; bracteoles short, obtuse. Flowers: 92 usually, 
only surrounded by a short cup of bracteoles. Fruits globose about
