the leaflets of that plant are said by Mr. Don to be hoary 
beneath. 
With D. podocarpum it may be compared, on account of 
Its ascending round stem, and angular downy branches; 
but the 'description of the leaves and inflorescence of that 
plant will not apply to this. 
Upon the whole, we are disposed to believe that of the 
above species the D. sambuense will be found most nearly 
related to this. 
M. de Candolle gives the following definition of the 
extensive tribe to which Desmodium belongs. 
4 4 Embryo homotropous (having the same direction as 
the seed). Corolla papilionaceous. Stamens rarely sepa¬ 
rate, generally monadelphous, or diadelphous in different 
degrees, namely, being 9 and 1, or 5 and 5. Legumen 
divided across into one-seeded cells, or articulations. 
Cotyledons nearly flat, in the course of germination con¬ 
verted into folioles, which are furnished with pores. A very 
natural tribe, which is easily recognised, except in the 
following cases: viz., 1°. In a few genera, which cannot 
with propriety be separated from Hedysarum, the legumen, 
perhaps by the abortion of the upper cells, is one-celled, as 
Onobrychis, Eleiotis, Lespedeza, &c.; 2°. In a very few 
genera, which are referred to Loteae, and can scarcely be 
divided from that tribe, the legumen, by means of trans¬ 
verse contractions, becomes almost multilocular, as in • 
certain species of the genera Anthyllis and Medicago, in 
Nissolia, Sesbania, &c.’* 
D. dubium has nearly triangular branches, which are 
striated between the angles, and hairy along the angles, 
especially towards their joints. Leaves on long stalks, 
erect-spreading; the stipules ovate, acuminate, somewhat 
• falcate, arid, rather hairy; petiole angular, pubescent; 
stipellce small, subulate; lateral leaflets oblong, sta ked, 
obtuse, apiculate; the odd one larger, obovate, apiculate, 
all opaque on the upper side, green, and silky on the under 
side, glaucous and villous. Racemes terminal, lax, many- 
flowered, erect; rachis pilose; bracteez ovate, acuminate; 
arid, rather hairy, longer than the pedicels, soon lalling on. 
Flowers bright pink, in pairs; their pedicels nlitoim and 
pubescent; calyx somewhat campanulate, rather hairy, 
4-toothed; teeth acuminate; the upper two-lobed.
