A small, dei^ressed, smooth-leaved form of this species, with flowers no larger than 

 those of R. acris, and sometimes smaller, occurs on the sea shore around Bedford Basin, 

 Nova Scotia, and a similar one is occasionally found in poor wet soils inland, but it 

 appears to be quite a different plant from the R. nitidas of the South. (Chapman, FL, \i. 8.) 

 Watson (Bibl. Index) seems to identify Hooker's nitidus (which is obscure) with the latter. 

 A form in the Canadian Survey Herbarium, collected at Ottawa by Mr. Fletcher, and 

 referred by Prof. Macoun to var. nilidm (Chairman), is small, almost glabrous, with small 

 flowers, and closely resembles the Nova Scotian i)lant. 



In its several forms this species ranges over Northern Europe to Iceland, N. and W. 

 Asia, N. Africa, as well as over a large portion of North America, both as an indigenous 

 plant and in its weed-form in cultivated fields. It ascends to 2100 feet on the mountains 

 of Scotland. In Western America it extends south to California. It is a very variable 

 plant, the prolific mother of many book species. Proneness to variation, like adaptability 

 for cultivation, depends to a large extent u^ion the elasticity of a plant in suiting itself to 

 changed conditions. We see this well illustrated in the present species.
