trinervis, Bl. and D. retusus, Bl.; but it differs from these in having winged fruit: it also resembles D. 
Dyeri, Pierre, which, however, has longer leaves with hairy petioles and more narrowly-winged fruit. 
Prate 180. Dipterocarpus Kunstleri, King. 1, leaf and ripe fruit; 2, two flowers from which the petals and 
stamens have fallen: of natural size. 
Vatica, Linn. 
Large or moderately sized resinous trees. Leaves coriaceous, entire, feather-veined 
and finely reticulate; stipules small, fugacious or inconspicuous. Flowers in axillary and 
terminal panicles, usually tomentese before expansion. Calyx-tube short, free, or adnate 
to the base of the ovary; segments somewhat acute, imbricate, then sub-valvate. Stamens 
15; anthers oblong, external valves larger, connective apiculate. Ovary 3-celled; style 
short, subulate, or apex clavate or capitate; stigma entire or 3-toothed ; ovules 2 in each 
cell. Fruit leathery, indehiscent, 1-seeded, surrounded by and sometimes partly adnate 
to the accrescent, membranous, nerved and reticulate calyx-lobes, two of which expand 
into narrow wings 2 or З in. long, the other three being much smaller. Cotyledons 
fleshy.

VarICA PERAKENSIS King in Journ. Аз. Soc. Bengal, for 1893, pt.2, р. 103. 
Nat, Ord. Dipterocarpeæ. 
A tree 60 to 80 feet high; young branches slender, deciduously scurfily stellate- 
pubescent, the bark rather pale. Leaves thinly coriaceous, oblong-lanceolate, or oblan- 
ceolate, more or less bluntly acuminate, sometimes caudate, the base cuneate; both 
surfaces glabrous, the midrib on the upper puberulous; main nerves 8 to 12 pairs, 
rather prominent beneath; length З to 4 in. breadth 8 to 1:3 in., petiole '4 to 
“5 in. Panicles axillary and  extra-axillary, cymose, crowded near the ends of the 
branches, 1 to 2 in. long, minutely pale tomentose as are the ovate-lanceolate 
ealyx-lobes. Flowers "4 in. long. Petals narrowly oblong, obtuse, glabrous. Stamens 15, 
anthers ovate and slightly apiculate. Ovary minutely tomentose; stigma conical. Ripe 
fruit *3 in. in diam., globose; the style persistent, minutely tomentose, quite free from 
the calyx; the two accrescent calyx-lobes oblong-oblanceolate, obtuse, obscurely 5-nerved, 
2:75 in. long and ‘75 in. broad; minor lobes unequal, lanceolate-acuminate, the 
largest about :85 in. long.

The nearest ally of this is Райса Bintamensis, Benth. and Hook.; but that has rather larger and 
more coriaceous leaves which are perfectly glabrous; larger flowers with petals scaly externally and 
a more scurfy inflorescence; moreover, the whole of the accrescent calyx-lobes of its fruit are more 
coriaceous and the minor lobes are blunter. 
Prats 181. Райса Perakensis, King. 1, flowering branch; 2 and 3, ripe fruits with their wings; 4, ripe fruit with 
all the calyx-lobes removed: of natural size; 5, ealyx opened up; ба, petal: slightly enlarged; 6, stamens; 7 
` pistils with vertical section of ovary: much enlarged.
