nials. Soil, sandy loam. Increased by seeds. Some are 

 pretty, but not of much importance. 



Ononis. Rest-harrow. [Leguminosae.] A genus of hardy 

 and half-hardy perennials and annuals. Some of the sub- 

 shrubby species are suitable for large rock-work. Soil, sandy 

 loam. Increased by seeds. 



Onosma. [Boraginaceae.] Perennial herbs, mostly hardy, 

 and many of them pretty subjects for rock-work. The flow- 

 ers are tubularly bell-shaped, and in all cases yellow or yel- 

 lowish. They grow best on dry and rather sandy soil, such 

 as exposed rock-work, being very liable to rot off in damp, 

 confined places; and the tenderer ones need protection from 

 wet in »winter. When seeds can be got, they make the best 

 plants : they should be sown about May, either in pots for 

 subsequent transplantation, or in the situations where they 

 are to remain. If seeds cannot be had, they must be in- 

 creased by cuttings of the young shoots, planted in sandy 

 soil, and placed under a hand-glass.
