Hab. a. Canada. Lady Dalhousie; Mrs. Percival ; Mrs. Skeppard. (i. Dry banks on the Red River 

 and Saskatchawan, (Douglas,) to the Prairies in the vallies of the Rocky Mountains. Vrummond, — My 

 Canadian specimens from Lady Dalhousie and Mrs. Percival much more resemble the fi^^ures in the 

 Botanical Magazine and Register^ than those from the more western parts of North America : and certainly, 

 as Mr, Lindley observes, approach the O. grandiflora, as they do also the O. ambigua; both natives of 

 Siberia. Nor is this species far removed, or readily distinguished by words, from some states of O. Uralensis.

Hab. a. and 5. Carlton-House on the Saskatchawan to the Rocky Mountains, {Drumnwnd,) and as far as 

 the sources of the Columbia. Douglas, i. and %. Bear Lake to the Arctic shores and Islands. Dr. Jiickardson ; 

 Capt Sir J. Franklin and Capt. Bach; CapU Sir E. Parry ^ §*c.— In the degree of pubescence, in the form 

 of the leaflets, in the colour of the hairs of the calyx, and size of the flowers, this plant is very variable. 

 The var. y. sulphurea, corresponding almost exactly with the O. sulplmrea of Dr. Fischer, (the O. campestris 

 y. of De Candolle,) is exceedingly beautiful, not only in the silkiness of its foliage, but in the size and bright^ 

 ness of the corollas.
