•5-1-25 in. long, •35-'75 in. wide, glabrous on both surfaces, dark-green 

 above, glancescent beneath, secondary veins few, faini, widely reticulated; 

 petiolules -15 in. long. Injlorescenre a large terminal thyrsoid panicle of 

 unbrancbed racemes 1-5-2 feet long, 8-9 in. wide, the single racemes 

 8-10 in. long, faintly puberulous as in tlie main-rachis ; pedicels slender 

 •35-45 in. long, distinctly puberulous, jointed '2 in. under base of calyx. 

 Oa?2/^ quite glabrous, leathery, anterior sepal deeply oucullate obtuse, 

 •25 in. long, the rest orbicular, all gland-dotted as is the shallow tube. 

 Corolla -5 in. across, bright-yellow, petals ovate-orbicular, upper smaller 

 than the others. Stamens far exserted, hirsute at bape, declinate, un- 

 equal. Ovarij declinate, about 5.ovu1ed ; stigma slightly fringed. Fod 

 only seen very young ; wing half as wide as body of pod.

A species very near If. andamanicum, with wliich it agrees in number, size, and 

 disposition of leaflets, and which it closely resembles in flowers. The different 

 shnpe of the leaflets, however, and especially the much shorter distance between the 

 ioint in the pedicel and the base of the calyx, with the much shorter puberulous 

 pedicels, mark it as abundantly distinct. The wing, too, of the very young pod is in 

 M. Kunstleri almost twice as wide as the wing in the corresponding stage of the pod 

 in M. andamanicum.

 2. 131. A large climber, branches glabrous with a few scattered 

 prickles. Leaves 1-1*5 feet long, pinnse 4-10, 5-7 in. long, leaflets 8-10, 

 alternate, rigidly subcoriaceous, obovate, slightly retuse, base cuneate 

 slightly unequally decurrent on the short petiolule, •5-1-5 in. long, 

 •35-1 in. wide, glabrous on both surfaces, dark- green above, pale beneath, 

 secondary veins few faint widely reticulated ; petiolules '15 in. long. 

 Inflorescence a large terminal thyrsoid panicle of unbranched racemes 

 extending into the axils of the uppermost leaves, 2-2*5 feet long, 1 foot 

 wide, the single racemes 10-12 in. long, quite glabrous as are the main- 

 rachis and the slender pedicels •5-75 in. long, jointed '3 in. under base of 

 calyx. Calyx quite glabrous, leathery, anterior sepal deeply cucullate 

 obtuse, '25 in. long, the rest orbicular all reticulate-veined and yellow 

 gland-dotted as is the shallow tube. Corolla '5 in. across, rather pale- 

 yellow, petals ovate-orbicular, the upper smaller than the others with 

 a thickened claw prolonged into a ligular ciliate ridge, the rest with 

 claw hirsute internally and with lamina red-blotched at base and pink- 

 veined. Stamens far exserted, hirsute at base, declinate, 2- seriate, free, 

 unequal. Oi^ar^/ declinate, ovules about 6; stigma slightly fringed. Fod 

 thin, 5 in. long, when ripe 1-1*5 in. wide (including posterior wing 

 *25-*35 in. wide), finely wide-reticulated, distantly 3-5-seeded.
