Mr. Wray gives ' Aker-tii^ha ' as the Malay name of this species. It has a 

 true Derris pod but differs markedly from the other species by its standard silky on 

 the outside. When they are only in flower and the leaves of both are still yonng it 

 is very diflBcult without careful examination to distinguish this species from Millettia 

 pachycarpa. This is Zollinger's Pongamia voluhilis of which there are authentic 

 specimens at Calcutta ; it is also said by Mr. Bentham to be the same as P. Hors- 

 fieldii Miq. and P. hypoleuca Miq. ; neither of these is represented in Herb. Calcutta. 



13. Derris malaccensis Prain. A rather slender creeper 30-50 

 feet long with glabrous branches. Leaves 9-15 in. long, bright-green, 

 leaflets 5-7 (rarely 9), subequal, subcoriaceous, elliptic, base rounded 

 apex caudate-acuminate, 4-6 in. long 2-2*5 in. wide, the caudate tip 

 •35-*6 in. long, glabrous on both surfaces, rachis 6-8 in. long, glabrous 

 hardly grooved above, petiolules '25 in. glabrous, lateral veins about 5 

 pairs indistinct. Floiuers in solitary axillary racemes 4-6 in. long always 

 much shorter than the leaves, nodes produced in stalks *15-2 in. long 

 each bearing one or several subequal pedicels, rachis and pedicels 

 glabrescent, the pedicels filiform '25 in. long bracteolate at base and 

 witli 2 small lanceolate bracteoles very near base of calyx. Calyx '\6 

 in. long reddish, wide-campanulate, glabrous except the ciliate slightly 

 sinuate margin. Corolla white or yellow tinged with pink, '6b in. long, 

 standard orbicular truncate or subcordate at the 2-callose base. Stame7is 

 monadelphous. Ovary densely rusty-pubescent ; ovules 4-5. Pod oblong 

 winged or not, glabrous, 1-4-seeded, 2-3 in. long. 



Var. typica; pod 15 in. wide, winged along the upper suture, some- 

 times along both. Derris cuneifolia var. malaccensis Benth. Journ. Linn. 

 Soc. IV, Suppl. 112.
