1557. Orobus. From o^m, to excite, and /Sy?, an ox ; that is to say, a food nourishing to cattle. Hand- 
some plants, and free flowerers. O. luteus Haller considers as one of the handsomest of the papilionaceous 
tribe. O. tubcrosus, according to Lightfoot, is in great esteem among the Highlanders of Scotland for the 
tubercles of the root ; they dry and chew them in general to give a better relish to their liquor; they also 
affirm them to be good against most disorders of the thorax, and that by the use of them they are enabled 
to repel hunger and thirst for a long time. In lireadalbane and Ross-shire, they sometimes bruise and steep 
them in water, and make an agreeable fermented liquor with them. They have a sweet taste, something 
like the roots of liquorice, and when boiled are well flavored and nutritive, and in times of scarcity have 
served as a substitute for bread. {Lightfoot.) 
Boiled well, a fork will pass through them, and dried slightly and roasted, they are served up in Holland 
and Flanders in the manner of chesnuts, which they resemble in flavor. Dickson [Hort. Trans, ii. 359.) 
recommends cultivating them in a bed or border of light rich soil, paved at the depth of twenty inches, to 
prevent their roots from running down. Plant the tubers six inches apart, and three inches below the surface ;
