two upper somewhat united. Corolla rose-purple, '45 in. lonp^, standard 

 oblong, base cordate 2-glandular. Stamens monadelplious. Ovary 

 densely pubescent, ovules 5-8. Pod ]-5-seeded narrowed to botli ends 

 1-2-5 in. long, winged along the upper suture.

None of the large suites of specimens sent to Calcutta has fruit ; Mr. Baker 

 describes the pod as exactly like that of D. robusta ; he however describes D. robusta 

 as having a glabrous pod which is never the case. Further Mr. Baker has described, 

 the leaflets of this species as 'glabrous' and on this account Father Scortechini has 

 proposed for the Perak plant the name D. dalbergioides var. dasyphylla, to be 

 distinguished by its pubescent leaflets from Mr. Baker's plant. The leaves of the 

 original specimens collected by Parish and Maingay have, however, leaflets pubescent 

 on both surfaces exactly as in the Perak plant. 



§ 3. EuDERRis. Robust climbers with medium to large leaflets ; 

 flowers rather large fasciculate on tumid or produced nodes in axillary 

 panicles ; stamens monadelphous ; base of vexillum without callosities ; 

 pod thin, broadly oblong or suborbicular, obtuse, winged only along the 

 upper suture. 



6. Derris uliginosa Benth. PI. Jungh. 252. A widely spreading 

 shrubby climber sometimes 40 feet long, with glabrous brandies ; stems 

 2-3 in. in diam. Leaves 5-8 in. long, leaflets usually 5, but very often 3, 

 casually solitary, the terminal exceeding the others, rigidly subcoriaceous, 

 ovate, acuminate or caudate- acuminate, base always rounded, 3-5 in. 

 long, 1-5-2-5 in. wide, polished above quite glabrous on botli surfaces, 

 lateral nerves 7-8 pairs, very faint, looping at their ends some way 

 within margin, bright green above paler beneatii, rachis 2-5 in. long, 

 channelled above and glabrous as are the petiolules "25 in. long, secon- 

 dary nerves indistinct. Flowers in rather short showy axillary racemes, 

 3-5 in. long, with nodes produced into short stalks each bearing one or 

 several subequal pedicels the flow^^rs of a fascicle opening subsimul- 

 taneously, rachis and pedicels glabrous, the node-stalks -15 in., the 

 pedicels proper as long, bracteolate at base and again 2-bracteolate a 

 little below the calyx. Calyx '15 in. long, subglabrous except the 

 shortly ciliate subtruncate margin, rather wide-campanulate. Corolla 

 delicate rose-pink, "4 in. long, standard orbicular base subcordate eglan- 

 dular. Stamens monadelphous. Ooary finely puberulous, ovules 5-7. 

 Pod obliquely rounded-oblong 1-5 in. long, 1*75 in. across, glabrous, 

 pale straw-colour when ripe, thin, flat, distinctly reticulatelj-veined"; 

 seed solitary, yellowish-brown, much compressed, 1 in. long almost as 

 broad. Benth. in Journ. Linn. Soc. lY, Suppl. 107; Miq. Fior. Ind.
