imbricate in the bud. The petals form a papilionaceous corolla ; 
the obovate or obcordate standard, reflexed on anthesis, tapers at 
the base, though seldom forming a distinct claw. The wings 
shorter than the standard, and sometimes very short, are obliquely 
elongated, each supported on a short narrow claw, 
above which the base of the limb is produced into an oe 
auricle. The petals of the keel have also short claws, 
and are usually longer than the wings; the keel, 
obtuse at the apex, is curved or abruptly bent, and as 
it were obliquely truncate along its inferior edge. The 
androceum consists of ten diadelphous stamens, the 
filaments of the nine anterior being united below, form- 
ing a cleft tube open behind ; the anthers are introrse, 
all uniform. The sessile or shortly stipitate ovary 
contains a variable number of descending campyloptro- 
pous ovules, whose micropyles lock upwards and 
outwards, is surmounted by a slender hollow style, 
abruptly inflexed, and ends in a little undilated stigma. ess

pod, containing several seeds, and /omentaceous—1.e., 
dividing transversely at maturity into as many indehiscent joints 
as there are seeds. Each joint represents a sort of achene. It 
is smooth or muricated, and contains a reniform exarillate exal- 
buminous seed, with an inflexed radicle. Hedysarum consists of 
perennial herbs, undershrubs, or more rarely shrubs. Some fifty 
species’ are known from the temperate regions of Europe, North 
Africa, Asia, and Noh America. The leaves are imparipinnate, 
with scarious stipules, but no stipels. The flowers form axillary 
racemes, and are themselves axillary each to ascarious or setaceous 
bract, and accompanied by two lateral bractlets placed some way 
up the pedicel, usually close against the flower. 
Next to Hedysarum come on the one hand Zaverniera, Stracheya, 
Ewersmannia, Athagi, and Corethrodendron, which have the same flower 
and several-jointed seed, but differ in the form of the fruit and in habit;
