HAB. Common in pastures and by the roadsides. 
FL. Throughout the year. 
Stem, when growing in thickets, suberect, but, in open 
clear places, procumbent and rooting at the base, afterwards 
ascending. Branches long, simple, towards their extremities 
somewhat angulose. Leaflets petiolulated, the middle one the 
largest, oblongo-ovate or elliptic, minutely apiculated, nerved, 
veined, subglabrous or hispidulous, with minute hooked hairs 
above, incano-pubescent (approaching to villous) beneath : pe- 
tiole channelled above, coloured, hispidulous. Stipules half the 
length of the petiole, broad at the base, .acuminate at the apex, 
ciliated, marescent : stipels setaceo-subulate. Racemes ter- 
minal, or afterwards, from the stem elongating by a develop- 
ment of a bud in the axil of the subterminal leaf, opposite to a 
leaf, 4-6 inches in length, filiform, striated : pedicels solitary, ^ 
an inch in length, furnished at the base with three small lanceo- 
late (the centre one the largest) bracteas. Flowers small, 
purple. Calyx ebracteolated, coloured, ciliated: upper lip bifid; 
under 3-partite with the divisions lanceolate. Standard obo- 
vate, emarginate ; wings obovato-oblong, rather larger than 
the keel; keel bifid at the apex. Stamens 9 and l. Ovary 
linear, pubescent : style short : stigma obtuse. Legume usually 
deflected, 6-7-jointed ; joints semi-orbiculate, hispid with 
minutely uncinate hairs. 
The leaves of this species vary very much in shape. In 
thickets the oblong figure prevails ; whereas in open clear 
places they approach to roundish. It is a very common weed 
in pastures, and troublesome, from the joints of the pods at- 
taching themselves to the clothes. The specific designation of 
hoary is applied, from the under surface of the leaves being 
incano-pubescent. 
I consider H. supinum of Swartz to be merely a variety of 
the present species.

modium. 
Stem erect herbaceous hispid with hooked hairs 
suffrutescent at the base, leaves ovali-oblong hispid 
on both sides hirsute along the nerves beneath, sti-
