The pods of this are not quite ripe. Mr. Ridley's field-note says they are 

 hairy ; should they prove to be quite persistently so it will probably be necessary 

 to recognise in this plant still another species to be named Ormosia Bidleyi. 



56. Ormosia sumatrana Prain, Joum. As. Soc. Beng. lxvi. 2. 150; 

 leaflets 7-9 (rarely 5), short-stalked, veinlets beneath slender raised, 

 pedicels shorter than calyx, pod subcompressed with thin valves, seed 

 oblong ; racemes in lax spreading panicles. 



Malacca ; Brisu, Holmberg ! Distrib. Sumatra. 



A very great tree, with thinnish branches, grey-silky at length glabrescent. 

 Leaflets ovate, or ovate -elliptic or obovate, 2-4 in. long, nerves spreading but pro- 

 minent below, pale-green glabrous and glossy above, puberulous at length glabrescent 

 beneath, rounded at base. Branches of panicle laxly spreading, tawny-silky. Calyx "2 

 in. long. Corolla pinkish-white with lilac-purple markings, *35 in. long. Ovary densely- 

 puberulous almost always 3-ovuled. Pod irregularly orbicular if 1-seeded, oblong if 

 2-seeded, 1 in. across, 1-1*7 in. long, lineate between the seeds ; valves thin woody 

 rigid black glabrescent. Seed *4 in. long, *35 in. wide, bright-red, without arillus. 



Closely related to 0. microsperma but very distinct by its more lax inflorescence, 

 smaller flowers, larger seeds and different leaves and bracts.

Subgen. 1. Guilandinia Linn. 



26. C^salpinia minax Hance, Joum. Bot. xxii. 365 ; var. burma- 

 nica Train ; leaves stipulate, leaflets small, bracts very large enveloping 

 the young flowers in a strobilate head ; bristles of pod subadpressed 

 and pubescent. 



Burma ; Shan States, Fort Stedman and Saga, King's Collectors ! 

 Distrib. China (var. typica.) 



Shrubby diffuse, branches at first downy at length glabrescent, with numerous 

 straight or slightly hooked hard prickles. Leaves 1 foot long or more, pinnge 10-12, 

 leaflets 6-10 pairs subsessile elliptic or oblong, setaceous apiculate ; stipules subulate 

 rigid 2-3-fid. Racemes long-peduncled many-flowered, simple sparingly branched 

 near base ; bracts large oblong-acuminate, tomentose, *75 in. long, *5 in. wide, pedicels 

 •6 in. long, (in fruit becoming 1*25 in. long). Calyx *75 in. long. Petals obovate 

 white, 1 in. long. Pods hardly stipitate, 4 in. long, nearly 2 in. wide, elliptic-oblong, 

 compressed, apex obtuse and beaked near lower corner. Seeds 6-7, '75 in. long, 

 *35 in. wide, almost cylindric, testa black. 



There being no specimen of the true Csesalpinia minax at Calcutta with which 

 to compare the Shan Hill plant above described, a specimen was sent to London for 

 comparison with the type of Mr. Hance's species which is preserved in the British 

 (Natural History) Museum collection. The comparison has been most kindly made 

 by Mr. E. G. Baker and Mr. Britten ; Mr. Baker has supplied the following note : — 



" The Burmese plant is certainly very closely allied to C. minax Hance but differs 

 " in the following points. The legume of C. minax is shorter by about f in., the
