25. Pasania costaTa, Gamble. A tree reaching a height of 
18—24 m. and 60—90 cm. in diam. of stem, branches spreading ; 
branchlets rather stout with smooth brown bark and small lenticels, 
the youngest slightly lepidote soon becoming glabrous; leaf-buds 
lanceolate with linear slightly falcate nearly glabrous scales about 
1 em. long. Leaves thickly coriaceous ; elliptic-oblong or elliptic- 
lanceolate or -oblanceolate, abruptly caudate at apex, the acumen 
obtuse, acute or almost rounded at the base which is slightly 
decurrent on the petiole; upper surface bright green when fresh, 
olive-brown, shining and glabrous when dry, lower glaucescent, 
dull; margin entire, slightly recurved when dry ; 10—20 em. long, 
4—7 cm. broad; midrib very stout, prominent on both surfaces ; 
main nerves 10—14 pairs, indistinct, straight at first, then curving 
to meet in loops near the margin; transverse nervules irregular, 
distant, enclosing the minutely areolate reticulation which is con- 
spicuous on both surfaces; petiole 7—17 mm. long. Spikes termi- 
nal or axillary, ¢ or 9 or ¢ and ? together the latter the highest, 
minutely grey-puberulous: ¢ up to 25 cm. long, slender but stiff : 
2 about 15 cm. long, slender; bracteoles of ¢ conspicuous in bud, 
linear-subulate, 2—3 mm. long. Flowers: ¢ in clusters of usually 
3, each cluster to a bracteole; perianth cup-shaped, 1 mm. long, 
cleft halfway down into 6—7 rounded lobes; stamens 12—15, 
filaments long, slender, anthers ovate apiculate; pistillode large, 
white-villous: ¢@ solitary, distant, the cupule fiattened on the 
rhachis, perianth-lobes as in ¢ but smaller; styles 3, very short. 
Fruits in stout spikes about 15 cm. long, distant, very large, 4°5 
em. in diam. when mature, 2°5 cm. high, very broadly turbinate, 
obliquely set on the very thick 1:5 cm. long pedicel which is ringed 
near the middle; rhachis like the branchlets; cupules when young 
embracing most of the acorn, turbinate and about 5-ringed, when 
mature obconic, minutely hoary, separate from the acorn but 
ineurved over it for about 5 mm. at the top; lamellae 2, wide and
