 ancho, to strangle ; supposed to kill the plants

 an ox ; the Orobus of Theophrastus was the

 Linn. 17, Or. 4, Mat. Or. Fab&cew. The 

 plants of this genus deserve to have a place in 

 every flower-border, on account of their very 

 elegant pea-blossoms. Any light soil suits 

 them, and they are readily increased by divi- 

 ding the plants at the roots in spring, or by 

 seeds. Synonymes: 1, 0. atropwrpHreus, Oro-
