NEW AND EAEE MALAYAN PLANTS. 143 



This species is allied to //. odorata, Eoxb. of Tenasserim, but 

 has smaller leaves more coriaceous, fewer nerved, and mor.3 

 abruptly acuminate, flowers distinctly pedicelled (not sessile 

 as in 11. odorata), petals smaller and the filaments different in 

 shape. 



Hopea Lowii, Brandts. This moderate sized tree has not pre- 

 viously been recorded from the Malay Peninsula. I have met 

 with it at Chua Chu Kang, (No. 6685 of my collections) but 



1 believe the only tree I ever saw there is gone now : and I have 

 had it also from Muar, and Penang Waterfall (Curtis 3635). 

 It is also a native of Borneo and Sumatra. 



Durio singaporensis, n. sp. (Malvaceae). A large tree. L^avus 

 oblong, obtuse or subacute, base blunt rounded, coriaceous, 

 glabrous above, with channelled midrib, beneath scaly raw 

 sienna colour, nerves very numerous, and inconspicuous above, 

 and hardly distinct beneath, 7-9 inches long, 2*5-3 inches wide : 

 petiole thick -25 inches long, angled. Flowers in clusters of 



2 or 3 on the trunk : peduncles short : pedicels *5 inches long. 

 4-angled, with 2 lanceolate bracts at their bases : floral bracts 

 ovate, acute, 1 inch long and as wide. Sepals oblong, 2 inches 

 long, acute, scaly, cinnamon colour. Petals linear, oblong, 

 1*5 inches long, outside scaly with fringed scales, cinnamon 

 colour, within pubescent white. Stamens and pistil like those 

 of D. malaccensis, Griff. 



Singapore: Bukit Timah (Ridley 3204); Ang Mo Kio 

 (Ridley 6676); Seletar. Johore : in Johore Bahru (Ridley 

 6677), and Mount Austin (Ridley 11996). 



Scaphiutn longiflorum, n. sp. (S terculiacece) . Tree. Leaves 

 coriaceous, elliptic rounded, shortly acuminate, blunt, some- 

 times glaucescent beneath, nerves 7 pairs strongly raised, and 

 the reticulations conspicuous beneath, above smooth, 4-5 to 6 

 inches long, 2-8 to 3 inches across : petiole 2*2 inches long. 

 Panicles axillary, 6 inches long, sparingly red-tomentose, com- 

 pact, much branched. Floivers numerous glabrous : bracts 

 caducous : pedicels glabrous, -1 inch long. Calyx *3 inches 

 long; tube cylindric, *2 in. long: lobes 4, much shorter, ovate, 

 acute, all glabrous except the inner edges which are woolly. 

 Stamens 8, in a globose woolly head, staminal column longer 

 than the calyx tube, woolly. 



Perak: (Scortechini 2077 and 2026). 



I have seen no female flowers or fruit of this species which 

 was confused with S. affine, but from which it is very distinct 

 in its long tubed glabrous flowers and woolly long androecium. 

 The panicles are also much more glabrous. 



I consider it advisable to keep the genus Scaphium distinct 

 from Sterculia from which it differs not only in its membra- 

 nous one-seeded carpels but also in the form of the flowers. 

 Besides this there are known four other species.
