Ononis viscosa

Ononis viscosa is an annual or short-lived perennial herb of the Fabaceae native to the Mediterranean region, including southern Europe, North Africa, and the Near East. Plants are erect, 20 to 80 cm tall, and densely covered with glandular hairs that exude a sticky, aromatic resin giving the species its specific epithet. The trifoliate (sometimes simple) leaves have small, narrow leaflets with toothed margins, and stipules adnate to the petiole. Yellow papilionaceous flowers, often streaked or veined with reddish-purple, are borne singly or in pairs in the axils of upper leaves on long pedicels. The fruit is a pendent, glandular-hairy legume containing several seeds. Ononis viscosa grows on dry hillsides, fallow fields, sandy soils, and roadsides at low to moderate elevations, flowering from spring into summer.
