but has broader leaves and much, more condensed panicles than that 

 species. 



3. Retinodendeon Kunstleri, King n. sp. A tree, 20 to 50 feet 

 high, sometimes a shrub : young branches slender, deciduously stellate- 

 puberulous. Leaves thinly coriaceous, elliptic-oblong to oblong-lanceo- 

 late, sometimes slightly obovate, sub-acute or shortly and bluntly 

 acumiuate ; the base cuneate, rarely rounded : upper surface glabrous, 

 the midrib and nerves pubescent ; the lower quite glabrous ; main nerves 

 7 to 9 pairs, ascending, slightly prominent beneath : length 225 to 4'5 

 in., breadth 1*25 to 1*75 in., petiole "25 to '4 in. Racemes axillary, I 

 to 1"5 in. long, sparsely scaly. Flowers - 4 in. long. Calyx-lobes ovate- 

 lanceolate, puberulous. Petals oblong- elliptic, oblique, obtuse, puberulous 

 outside. Anthers slightly and sharply apiculate. Ovary puberulous, 

 stigma capitate. Ripe fruit globular, with a long curved apical beak, 

 glabrous, about *25 in. in diam. Calyx-lobes all accrescent, sub-equal, 

 oblong, tapering slightly to the sub-obtuse apex, the base slightly 

 auricled, thickly membranous, glabrous, 3-nerved, the longest about 

 1*3 in. long, and "35 in. broad, loosely surrounding, and longer than, the 

 fruit. 



Perak ; Scortechini, Wray, King's Collector ; very common at low 

 elevations. 



In this species all the five calyx-lobes are accrescent and of nearly 

 equal size. They are quite free from the ripe fruit, round which they 

 form a loose semi-inflated investiture. Its nearest ally is Yatica 

 bancana, Scheffer, (Retinodendron bancanum). 



8. Isoptera, Scheffer. 



A tall resinous tree. Leaves coriaceous, entire, feather-veined. 

 Floioers in axillary or terminal panicles. Calyx-tube very short, the 

 segments ovate-rotund, imbricate. Stamens 30 to 35, the anthers ovate, 

 the cells divergent at the base, acute, the valves equal, the connective 

 produced into an apical bristle-like appendage. Ovary 3-cellecl, thelocnli 

 bi-ovulate ; the style short, terete, 3-angled at the apex. Fruit indehis- 

 cent, 1-seeded, the pericarp coriaceous. Fruiting -calyx an open cup 

 not embracing the fruit ; its lobes all slightly enlarged, spreading* (not 

 winged) ; the outer 3 rotund, broader than the 2 narrower inner lobes. 



One species — Malayan.

 Jard. Buitenzorg VI, 222. A large tree : young branches slender, 

 dark-coloured, sj^arsely lenticellate, glabrescent. Leaves coriaceous,
