2. Mezoneuron htmenocarpum W. & A. Prodr. I, 283. A large 

 climber, branches finely puberulous, with a few scattered recurved 

 brown prickles^ Leaves 1-15 feet long, pinnae 1-10, 3-4 in. long, leaflets 

 10-14, alternate or subopposite, rigidly subcoriaceous, obovate, apex 

 obtuse or rounded, base cnneate unequal, '5-1 in. long, •25-'6 in. wide, 

 puberulous above, puberulous to densely pubescent beneath, secondary 

 veins 5-6 pairs very faint ; petiolules '15 in. long. Injlorescence a large 

 terminal thyrsoid panicle of unbranched racemes extending into the 

 axils of the uppermost leaves, 2 feet long, 8-10 in. wide, the sin;>^le 

 racemes 6-8 in. long, puberulous as are the main-rachis and slender 

 pedicels, '35-5 in. long, jointed -15 in. under base of calyx. Calyx 

 densely puberulous, leathery, anterior sepal cucullate subacute, '25 in. 

 long, the others orbicular. Corolla 'b in. across, yellow, petals ovate-

 unequal. Ovary declinate, about 5-ovuled ; stigma slightly fringed. 

 Pod thin, 4 in. long, when lipe 1 in. wide (including posterior wing 

 •25-*3 in wide), fidntly wide-reticulated, 5-seeded. Cxsalpinia liymeno- 

 carpa Wall. Cat. 5832. Mezoneuron pubesceiis Bak. iu Flor. Brit. Ind. If,

Andamans ; very plentiful near Port Blair, King's Collectors ! Dis- 

 trib. Burma ; Ceylon. 



Resembles M. andamanicum but is easily distinguished by its leaves and its 

 calyx being pubescent; by its pedicels being shorter; and by its pods being small ar 

 and not so distinctly reticulated. 



3. Mezoneuron Kunstleri Prain. A large climber, branches gla- 

 brous, with a few brown scattered recurved prickles. Leaves 6-8 in. 

 long, pinnae 4-6, 4-5 in. long, leaflets 6-S, alternate, subcoriaceous, ovate, 

 cuneate at apex and base, almost equally decurrent on the short petiolule,
