ONO'NIS. Restharrow. (From onos, an ass, and 

 onemi, to delight ; the ass delights to browse on the 

 herbage. Nat. ord. Leguminous Plants [Leguminosas]. 

 Linn. i6-Monadelphia, 6-Decandria. Allied to Paro- 

 chetus.) 



Annuals, by seeds in April, in sandy, deep soil ; 

 perennials and creeping shrubs, by division in spring, 

 and cuttings under a hand-light, in sand, in summer; 

 deep, sandy loam for most of them. Hardy under- 

 shmb kinds, if of a creeping nature, answer well for rock- 

 works. The tenderer species require a cold pit or a cool 

 greenhouse in winter, and most of these like a little peat 

 added to the sandy loam.
