biaoteoles under the calyx. Calyx '2 in. long, densely brown-silky, the 

 teeth triangular, the three lower as long as the calyx-tube the two upper 

 rather shorter. Corolla apparently white, '35 iu. long, standard •25 in. 

 across. Stamens quite free, incurv^ed, exserted. Ovary ovate, densely 

 silky, ovules 3. Pod orbicular, ] -seeded, or oblong and lineate between 

 the seeds if 2-3-seeded, shortly stipitate, valves ihin, rigid, at first 

 densely silky soon glabrescent and black externally, reddish-brown 

 inside. Seeds ovoid, '3 in. long, '25 in. wide, cinnabar-red, without

There is an authentic example of Macrotropis ? hancana Miq. at Calcutta ; it 

 belongs undoubtedly to this species. 



6. Ormosia sumatrana Prain. A large tree with tomentose 

 rather slender ultimately glabrescent branches. Leaves 8-10 in. long, 

 leaflets 7-9 (very rarely 5), ovate or ovate-elliptic or obovate, obtusely 

 a])iculate or subacumiuate, base rounded, coriaceous, pale-green, glab- 

 rous somewhat glossy above, hirsute but at length glabrescent beneath 

 as are the rachis and petiolules, 2-4 in. long 1-1"75 in. wide, the ter- 

 minal exceeding the others, nerves 8-10 pairs, spreading rather pro- 

 minent beneath. JRacemes in lax terminal panicles, 6-8 in. long and 

 almost as wide, with pubescent rachis and branches ; pedicels *1 in. 

 long, shorter than the calyx, bracts '1 in. long, oblong, very deciduous 

 as are the similar bracteoles at base of pedicels, the two brncteoles 

 under the calyx sub-persistent, lanceolate, *08 in. long. Calyx '2 in., 

 externally tawny-pubescent, three lower teeth ovate-lanceolate shorter 

 than tube, the two upper subconnate in a 2-lobed upper lip. Corolla 

 pinkish-white with lilac-purple markings, '35 in. long, standard orbi- 

 cular emarginate, '3 in. wide. Stamens quite exserted, incurved. Ovary 

 densely puberulous, almost always 3-ovuled. Pod irregularly orbicular 

 if 1-seeded, 1 in. across, oblong and 17 in. long if 2-seeded, lineate 

 between the seeds, the valves thinly Avoody, rigid, black and glabrescent 

 externally. Seed ovoid '4 yi. long, '35 in. wide, cinnabar-red without 

 arillus. Macrotropis sumatrana Miq. For. Ind. Bat. Suppl. 294.

Though very closely related to the next species, this is nevertheless easily 

 distinguished by its different leaves and tomentum, its lax panicles, its smaller 

 flowers, and its larger seeds. 



The Malacca plant here referred to 0. sumatra7ia has been only once collected ; 

 it has inflorescence and flowers exactly as in. sumatrana but it has not yet been 

 sent in fruit. While therefore we know that it differs from 0. microsperma and from 

 0. venosa it is not absolutely certaiu that it exactly ;igrees with O. sumatrana,
