224  LEGUMINOS X. Desmopium. 
truncated at both ends.—Small trees. Leaves pinnately trifoliolate. Pedun- 
cles axillary, solitary, much shorter than the petiole, bearing at the apex an 
umbel or short corymb: pedicels 1-flowered. Flowers white. 
tert this ought to form a distinct genus, and with that view we have not 
adopted the name of Eudesmodium given by De Candolle. We exclude D. lutescens, 
Desv. and DC., which does not differ from Dicerma elegans. 
692. (1) D. umbellatum (DC.:) arborescent: young shoots pubescent or 
villous somewhat angled: leaves trifoliolate; leaflets oval, obtuse, glabrous 
above, whitish-pubescent beneath, the terminal one the largest: stipules ca- 
ducous: peduncles axillary, much shorter than the petiole: flowers 10-12, 
somewhat umbellate: legumes 3-4-jointed, thick-margined, at first more or 
less villous, afterwards becoming more glabrous.—DC. prod. 2. p. 325 ; Wall.! 
L. n. 5687.—Hedysarum umbellatum, Linn. ! sp. p. 1053 ; Willd. sp. 3. p. 
1182 ; Spr. syst. 3. p. 316.—Burm. Zeyl. t. 51 (good). 
It is possible that more thàn one species may be comprehended under the 
above character: thus Wall. L. n. 5687, b, e, f, has the legumes villous ; a has 
them glabrous with the joints larger and more fleshy: in d they are slightly 
pubescent and villous along the sutures; but these agree in all other points. 
We have not seen Hed. arboreum of Roxburgh, but judging by his descrip- 
tion (fl. Ind. 3. p. 361) it seems referable to the present species. 
693. (2) D. congestum (Wall. :) arborescent: old branches glabrous; young 
shoots obtusely triangular, clothed with whitish pubescence: leaves trifolio- 
late ; leaflets oblong-lanceolate, nearly glabrous, except the white-pubescent 
parallel nerves beneath : stipules lanceolate-acuminated : peduncles axillary, 
solitary, several times shorter than the petioles : flowers numerous, somewhat 
umbelled : calyx-segments broad, about equal: legumes compressed, slightly 
ubescent, 4—6-jointed.— Wall. ! L. n. 5723 (partly) ; Wight! cat. n. 789.— 
Hedysarum umbellatum, Roxb. fl. Ind. 3. p. 360; in E. I. C. mus. tab. 399. 
Uircars. Travancore. : 
It is almost impossible, in the absence of fruit, to distinguish this from the 
wing ; and we think it therefore probable that some of the specimens dis- 
tributed by Dr Wallich under n. 5721 of his List, belong to D. congestum : 
this name, indeed, appears to have originated in a mistake for confertum, 
of which, although Dr Wallich refers it to n. 5721. a (partly), our specimens 
from Rottler's herbarium show to be what is here called D. congestum. 
* 694. (3) D. cephalotes (Wall.:) arborescent: branches obtusely triangu- 
lar, densely clothed when young with adpressed white silky pubescence, ai- 
terwards more glabrous: leaves trifoliolate ; leaflets oblong or oblong-lanceo- 
late, clothed with woolly or silky hairs when young, soon glabrous ; nerves 
parallel, woolly beneath: stipules scariose, acuminated : peduncles axillary, 
several times shorter than the petioles, many-flowered : lower calyx-segmen 
narrower and longer than the others: legumes densely villous, 2-3-jointed.—

or suffrutescent plants. Flowers never umbellate. Pedicels filiform, 1-

a. Leaves simple: petiole winged : joints of the legume broader than long, straight dor
