Ononis arvensis (Hairy Rest-harrow). 

 A variable perennial, sometimes 1 

 ft. or 18 in. high, but generally a low, 

 spreading, much - branched under- 

 shrub, thinly clothed with soft hairs, 

 more or less glutinous. Flowers, in 

 summer and autumn ; pink, the upper 

 ones deeper, either solitary on short 

 axillary stalks, or forming a short 

 leafy raceme ; corolla rather longer 

 than the calyx. Leaves, pinnately 

 trifoliate ; leaflets oblong, side ones 

 smallest ; branches often ending in a 

 thorn. There is a variety smoother, 

 more thorny and erect, sometimes 

 called 0. campestris ; and 0. arvensis 

 alba is a white variety. Very common 

 in Britain and throughout Europe. 



The white variety is a pretty 



border plant, and the other kinds, if 

 too common in some parts to permit 

 of their garden use, look very pretty 

 naturalized in rough places. Division
