r p JL HE common Reft-bar row grows in the borders of barren
fandy fields and by way-fides, flowering from June to Auguft.
Its root is perennial, very ftrong and woody, which has given
rife to its Englifh name. Stems annual, upright or procumbent,
round, woody, branched, leafy, hairy, their branches
in a barren foil and on an old root terminating in a fpine.
Leaves alternate, on foot-ftalks, elliptical inclining to a wedge-
ihape, furrowed, roughilh, toothed only towards their extremity
; the lower ones are often ternate. A pair of united
ftipulse embraces the item. Flowers for the moll part folitary,
axillary, on ftalks, of an elegant rofe-colour. Calyx hairy,
its teeth permanent, dilating as the fruit ripens. Standard
twice as long as the wings and keel. Pod fmall and rhomboid,
fcarcely longer than the calyx. Seeds tuberculated.
The foliage and calyx are more or lefs vifcid, with a peculiar
ftrong fmell.
We are perfuaded the Ononis fpinofa -is only the arvenfis or
inermis in an older or more ftarved ftate, and alfo that the. O.
repens is merely a procumbent maritime variety. 0. antiquorum
of Linnaeus really appears not to differ from that here delineated.
0 . Hrcina of Jacquin feems a good fpecies.
