Ononis spinosa

Ononis spinosa is a flowering plant belonging to the family Fabaceae, that is commonly known as spiny restharrow or just restharrow. It is found throughout much of Europe including Britain, but rarely as far north as Scotland. It is closely related to Ononis repens (common restharrow); the two are considered conspecific by the Plants of the World Online database, with O. repens treated as a subspecies of O. spinosa as Ononis spinosa subsp. procurrens. The Botanical Society of Britain and Ireland treats them as separate species.
