Identification. Lin. Gen., No. 863. ; Lam, Ill, t. 616. ; Dec. Prod., 2. p. 158.; Don’s Mill., 2. p. 158, 
Synonymes. Andnis and Natrix Mench Meth. 157. and 158.; Arréte-beeuf, or sometimes Bugrane, 
Fr.; Hauhechel, Ger. 
Derivation. Said to be from onos, an ass ; because only asses would feed upon so prickly a plant. 
Restharrow is a corruption of arrest, that is, stop, harrow ; from the long and deeply seated roots 
pposing a serious impedi tt to the plough or harrow. 
Gen. Char, Calyx campanulate, 5-cleft, with linear segments. Vewillum large, 
striated. Stamens monadelphous, the tenth one sometimes almost free. 
Legume usually turgid, sessile, few-seeded. (Don’s Mill.) 
Leaves trifoliolate, stipulate, alternate, deciduous. Flowers yellow, pur- 
plish and red, or rarely white. — Shrubs, very low, suffruticose ; natives of 
Europe. Two species are hardy. 
The peduncle is, in many instances, furnished with an awn, which is the 
petiole of an abortive floral leaf. Tie two specimens here described are well 
adapted for rockwork or flower-borders, on account of their lively flowers, 
which are red, or reddish purple; colours not frequently met with in the lig- 
neous Leguminaceas, by far the greater part of which have yellow flowers. 
They are readily propagated by seeds or by division, and 
will grow in any soil that is tolerably dry.

tundifolia. Several other species are hardy, but 
not sufficiently ligneous for our alae
