long, 1*25 in. wide, glabrous on both surfaces, lateral nerves 10 pairs 

 prominent on both sides running almost to margin of blade, rachis 3*5 

 in., glabrous as are the petiolules *2 in. long. Flowers in lax axillary 

 panicles 6-8 in. long, sparingly branched, branches 2*5 in. long or less, 

 spreading, nodes tumid but not produced into stalks, bearing one or more 

 unequal filiform pedicels, rachis and pedicels sparsely adpressed-puberu- 

 lous, the pedicels *2 in. long rather longer than the calyx, bracteate at 

 their base, 2-bracteolate close under the calyx. Calyx campanulate *12 

 in. long, subglabrous, purplish, margin sinuate-toothed, Corolla appa- 

 rently white, '35 in. long, standard orbicular ecallose. Stamens mona- 

 delphous. Ovary sparsely hairy ; ovules about 4. Derris uliginosa var.

Nearly related to D. marginata Bth. from which it differs mainly in having 

 shorter pedicels 2-bracteolate close nnder the calyx, nnd in having rather smaller 

 leaflets with more numerous nerves. It seems also very nearly related to the next 

 species from which it differs in its shorter panicles and its leaflets with more numer- 

 ous and more prominent nerves, It is besides nearly related to D. amcena but differs 

 in having thinner leaves, and laxer panicles with spreading not fastigiate branches. 



10. Derris flortrunda Benth. Journ. Linn. Soc. IV, Suppl. 105. 

 A stout rambling shrub with glabrous whitish branches. Leaves 4-5 in. 

 long, leaflets 3-5, pale-green, thinly coriaceous, broadly elliptic-oblong, 

 base rounded, apex shortly and obtusely acuminate, 2-2*5 in. long 1-1*5 

 in. wide, glabrous on both surfaces, lateral nerves 4 pairs very faint 

 beneath not visible above, rachis 3-4 in. long, glabrous as are the 

 petiolules '25 in. long. Flowers in long lax axillary panicles sometimes 

 15-18 in. long, sparingly branched, the branches 4-6 in. long, spreading, 

 nodes distant tumid, sometimes produced into stalks bearing 2-6 unequal 

 filiform pedicels, rachis and pedicels sparsely spreading-puberulons, the 

 pedicels *4 in. long, 2-bracteolate at base of calyx. Calyx campanulate 

 *12 in. long, purple-brown, margin crenate. Corolla white, '3 in. long, 

 standard orbicular ecallose with a green spot above the long claw. 

 Stamens monadelphous. Ovary sparsely puberulous, ovules 2-3. Bra-

The Pero.k specimens have pedicels rather more glabror s than the Java ones ; 

 otherwise they agree very closely. Miquel refers the plant doubtfully to Bra- 

 chypterum ; to the writer it seems as if its affinities were rather with Dipteroderris ■ 

 unfortunately the pod is still unknown. The Perak plant is 2-ovuled, the Java 

 one 3-ovuled, in all the flowers examined by the writer.
