226 LEGUMINOSA. DEsMODIUM. 
After having examined the Linnean specimens of D. maculatum and D. 
Gangeticum, we have no hesitation about uniting them: it is a common plant 
in India, and not unfrequently presents both supposed species on different 
branches of the same individual. 
c: Leaves trifoliolate. 
+ Legumes straightish on one suture, very deeply notched on the other: joints semi- 
circular, not truncated. p 
698. (7) D. Wightii (Graham:) herbaceous, diffuse: branches triangular, 
pubescent on the angles: leaves long-petioled, trifoliolate ; leaflets oblong- 
lanceolate, acuminated, upper side glabrous, under slightly pubescent: sti- 
pules subulate: racemes terminal, elongated, many-flowered : bracteas mi- 
nute, setaceous, about 3 together: pedicels in threes, slender, spreading: le- 
gumes glabrous, 6-8-jointed ; joints semicircular, not truncated.—Graham!

Very closely allied to D. suleatum, Graham! in Wall. L. n. 5736, which 
perhaps is only a more luxuriant state of the same plant. 
+ + Legumes deeply notched on both sutures : joints orbicular. 
699. (8) D. diffusum (DC.:) herbaceous, procumbent, diffuse, branched : 
branches 4-5-angled, hispidly pubescent: leaves trifoliolate ; leaflets oval, 
pubescent on both sides: stipules large, foliaceous, auricled and stem-clasp- 
ing: racemes terminating every branch, very long: bracteas small, lanceolate, 
2-3 together: flowers in pairs or threes: legumes ascending or nearly erect, 
5—6-jointed, notched on both sutures, hispid with short hooked hairs ; joints 
orbieular, tumid in the middle when mature: seeds oval, compressed, Wi 
the hilum at one of the narrow ends.— DC. prod. 2. p. 336; Wight! cat. n.

We can perceive no difference between Roxburgh's two species, nor be- 
tween these and the two described by Willdenow, and have therefore unit 
them all. Sprengel's Hed. Roxburghii, judging from the character given, 3P- 
pears to be very distinct, but we cannot determine what it is, the legumes 
being unnoticed.

clothed as well as the raceme with short adpressed hairs, angled; young 
shoots triquetrous: leaves bifarious, trifoliolate ; leaflets ovate or oval, gla- 
brous above, pubescent beneath: stipules lanceolate, acuminated : racemes 
terminal, drooping before the flowers expand, afterwards very long 1-2-feet) : 
bracteas lanceolate surrounding several smaller setaceous ones: flowers 8€- - 
veral together: legumes narrow-linear, straight on both sutures, clothed wit! 
short hooked hairs ; joints more than twice as long as broad.— Bec

Judging from Sprengel's short description, we have no doubt but H. Rott- 
leri, Spr. syst. 3. p. 320, or H. lineare, Rottl., is this species. D. elongatum, 
Wall. L. n. 5715, or Hed. diffusum, Roxb. (not Willd.), approaches also “4 
closely that we had almost considered it a variety: it appears, however, i 
bea diffus e plant with slender variously bent branches. We have
