Clammy Rest-harrow. Shrub. 



Cult. The greater part of the species of Ononis are rather 

 handsome when in flower. The hardy shrubby kinds are in- 

 creased by seeds and layers ; the hardy perennial kinds by di- 

 viding the plants of the roots in spring, or by seeds ; these 

 are well fitted for flower-borders. The seeds of the hardy 

 annual kinds only require to be sown in open borders in April. 

 The greenhouse and frame species thrive well in a mixture of 

 loam, peat, and sand ; these are usually increased by seeds, 

 which ripen in abundance ; they may also be propagated by 

 young cuttings, planted in sand under a bell-glass.
