Style longer than the stamens, cylindric, pubescent, not scaly : stigma 
capitate. Fruit unknown. 
Upper Perak at 300 feet ; Wray. 
The fruit of this is unknown. Mr. Wray describes the petals as 
pink. The caudnte-lanceolato leaves of this are different from those of 
any other Durio of the Malayan Peninsula. 
6. D. Oxleyanus, Griff. Notul. it. 531. A tree, the young branches, 
petioles and undor surfaces of the midrib adpressed-lepidote. Leaves 
elliptic-oblong, rounded at base and apex ; upper surface glabrous ; the 
lower softly pubescent, not scaly except on the midrib, the 15 to 18 
pairs of main nerves stout, sub-horizontal, prominent boneath ; length 
3'5 to 5 in., breadth 1'5 to 2 in., petiole '5 in. Flowers about 1 in. in 
diam., in few-flowered scaly cymes from the smaller branches. Invnlu- 
i-ral hi acts 2, broadly ovate, pubescent, sparsely and mi nu tely scaly. Calyx 
cup-shaped, the mouth with 4 broad shallow rather blunt teeth, inside 
glabrous, outside with many largo loose scales. Petals 4, oblauceolate 
or spathulute, little longer than the calyx, pubescent on both surfaces, 
not scaly. Stamens 20, shorter than the petals ; 5 free and alternating- 
with 5 phalanges of 3 each which are slightly united by the bases of 
their filaments : anthers solitary, drum-shaped, the dehiscence circular. 
Ovary depressed -globular, 4-celled, densely stellate-hairy. Style cylin- 
dric, pilose ; stigma capitate. Fruit unknown. Mast, in Hook. fil. PI. 
Br. Ind. i. 351 and Jonrn. Linn. Soc. xiv. 501, t. xvi, fig. 13 to JO.

This differs, as Beceari has well pointed out (Malesia 1. c), from 
the other species of Durio by the absence of scales from every part of 
the leaf except the petiole and midrib; by the single, not glomerulate, 
anthers ; by the hairy, not squamose, ovary. Should the fruit when 
f< mud also present differences, it may be desirable to create a new 
genus for this species. 
9. BoscniA, Korth. 
Trees. Leaves oblong, entire, scaly beneath. Flowers small, axil- 
lary. Bracteoles 2-3, connate at the base, deciduous. Calyx deeply 
4-5 parted. Petals linear- ligu late, entire or laciniate. Stamens many, 
simie free, others irregularly coherent, outermost without anthers; 
anthers globose, 1-celled, opening by a terminal pore, solitary, or in 
groups of 2-0. Ovary 3-5-celled, style elongate ; ovules one or more in 
each cell. Frail oblong, 3 to 5-celled, 3 to 5-valved, muricate. Seeds 
few, ovoid, half-covered by a fleshy, coloured, cup-shaped arillus; coty- 
ledons foUaceous. Species 4 : all Malayan.
