 DISTRIB. Europe, W. Asia, N. Africa. The two sub-species present no 

 constant characters, and authors are greatly at variance with respect to the 

 names they should bear. Wilkomin and Lange appear to have devoted 

 most time and study to them. They adopt the Linnean names for the 

 two principal forms (as does Boissier for the erect form), and they describe 

 a third intermediate one for O. arveii'-sis, L., to. which they refer O. 

 spino'sa a, L., O. iner'mis /8, Huds,, and O. procur'rens, Wallr., as syno- 

 nyms. It differs from re pens in the shorter standard and pods, and is 

 foetid and viscidly hirsute.

 branches usually bifarious, leaflets If near-oblong, pod usually equalling the

 is a maritime spinous form.

 dric oblong renexed.
