The flowers and young fruit show a five-ridged calyx. As the fruit matures, 
the hollows fill out and the fruit becomes more nearly spherical till finally the 
only remaining trace of the ridges is found in small, rounded protuberances,, on 
the upper part of the fruit, alternating with the calyx lobes. 
The common native name for this species is hagacliac. It is commonly found 
in those regions which have a comparatively even rainfall. It occurs on flat 
lands and low hills. It is gregarious in habit and frequently makes up the 
greater part of the stand where it occurs. 
Distribution: damp forests in the upper part of the Assam valley; Chittagong 
hills; Arracan; lower Pegu, hills between the rivers Sitang and Salween; Anda- 
man Islands; Sumatra; Bangka; the Philippines. 
2. Dipterocarpus affinis Brandis Journ. Linn. Soc. Bot. 31 (1895) 31. 
Plate XXXV. 
Branches and petioles stellate-tomentose. Leaves suhmembranaceous, 
oblanceolate, repand, blade 27 to 33 cm long; petioles 6 to 7 cm. 
Secondary nerves 24 to 28 pairs, straight, bent near margin and terminat- 
ing in reticulate intra-marginal veins. Tertiary nerves parallel and 
reticulate. Stipules linear, tomentose, twice as long as the petioles. 
Flowers large, short-pedicellate. Calyx-tube thickly coriaceous, tur- 
binate, smooth and glabrous, the lobes 2 linear, 3 short, reflexed.. Ovary, 
stylopodium, and lower part of style pilose. Pubescence the same as that 
of D. pilosus. Brandis says that the difference between the two species 
consists, in the narrow membranaceous leaves and the glabrous calyx of 
D. affinis , , the smaller segments in flower reflexed, and not erect. 
A number of specimens in our herbarium seem to At this description 
and have fruit with them, which shows the short calyx wings slightly 
reflexed, but in no case is the fruit collected with the herbarium material 
actually attached to it, the fruits seeming to- have been picked up from 
the ground. This leaves the suspicion that the membranaceous- texture 
of the leaves may be due to their being young or seedling leaves,, possibly 
immature forms of D. pilosus. The differences in the reflexed or erect 
calyx lobes are also very slight and might conceiveably be fortuitous or' 
due to drying. 
I have checked Brandis’ observation of the very close resemblance and 
possible identity of D. elongatus Korth. and D. affinis, and think it
