60 LAWSON: EB VISION OF THE 



erect-pateut, pubescent. Receptacle glabrous. Petals yellow, paler than those of R. 

 repens or biilbosm. The plant is slightly hoary with short pubescence, which gives it a 

 pale hue, whilst R. repens is always, in exposed places, of a dark green color.

An European plant, introduced and now common throughout the cultivated parts of 

 Canada, a weed in pastures and by waysides (much less abundant than R. repem, which 

 spreads rapidly with cultivation) ; not seen in woods remote from settlements. Common 

 in central Ontario, as about Kingston, &c., and also in Nova Scotia, as Halifax County, 

 Truro and other parts of Colchester. — Laivson. Montreal and St. Johns, Q. — Dr. P. W.

Animals reject this species, whilst they greedily eat R. repens. I have a very hairy 

 form, collected near Kingston, 25th July, 1860. 



In Sir Joseph Hooker's table of distribution of Arctic Plants (1860) this species is 

 entered as indigenous in N.W. and N.E. America. But, in the Students' Flora of the 

 British Islands, its distribution is given as follows : — Europe (Arctic) ; North Asia ; intro- 

 duced in America. Mr. Watson observes, in Index BibL, that it is generally regarded as 

 introduced in America. That this is the correct view there can be little or no doubt.
