LEGUMINIFER. 81 
diadelphous, the filaments not dilated. Style geniculate at the 
middle, with a capitate stigma. Pod sub-sessile, roundish or ovoid, 
much compressed laterally, reticulated, often muricated or spiny, 
1-seeded, indehiscent. 
Herbs or undershrubs. Leaves with numerous pairs of pinne. 
Stipules cohering at the base by the sides furthest from the petiole. 
Flowers red or white, axillary or terminal, in long stalked spike- 
like racemes. 
The generic name comes from ovoc (ones), an ass, and Bovyw (brucho), I gnaw, the 
plants being a favourite food of asses. é 
SPECIES IL—ONOBRYCHIS SATIVA. Lam. 
PuatE CCCLXXXI. 
Hedysarum Onobrychis, Zinn. Sm. Eng. Bot. No. 96. 
Rootstock somewhat woody. Calyx-tube campanulate, very 
short; teeth subulate, about twice as long as the tube, the lowest 
one a little shorter than the others. Wings little more than one- 
third the length of the standard and keel. Pods reticulated on the 
sides, with very prominent raised nerves, the lower margin with 
acute tubercles or short spines towards the apex. 
On chalky banks, cliffs, and borders of fields. Not uncommon 
in the South-east of England; but it is impossible to say in what 
stations it is native, and in what it is the remains of Saintfoin cul- 
tivation. 
England. Perennial. Summer and Autumn. 
Rootstock dividing at the apex into numerous branches, and 
terminating in stout tough stems, which are curved at the base, 
then erect, somewhat flexuous, 1 to 2 feet high. Leaves 3 to 7 
inches long; leaflets } to 2 inch long, varying from oval to strap- 
shaped, generally truncate and apiculate at the apex, and slightly 
narrowed towards the base. Stipules broadly lanceolate-acuminate, 
scarious, especially at the margins. Peduncles terminal, longer 
than the leaves, terminating in compact spikelike racemes, 2 to 4 
inches long. Pedicels scarcely so long as the calyx-tube, in the 
axils of scarious lanceolate bracts, which exceed them in length. 
Calyx more or less thickly clothed with woolly hairs. Flowers 5 
inch long, rose-colour streaked with crimson, and suffused with that 
colour at the apex of the keel; wings so short that on a cursory 
examination the flower might seem to consist only of the standard 
and keel. Pods pubescent, } to } inch long, olive-colour, much 
compressed, the upper margin nearly straight, the lower one curved 
into more than a semicircle, somewhat truncate at the apex,
