 It grows 1^—2 ft. high, and has sUghtly 

 downy trailing stems, and grey-green

 plant. There is a form of it called alba, 

 the flowers of which however are pale 

 creamy yellow and not white, as one 

 would imagine from the name.

CE. eximia {CE. marginata). — A 

 handsome perennial 9-12 in. high, from 

 the Eocky Mts. of Upper California.

 1-2 in. long, ovate-lance-shaped, finely 

 toothed. Flowers from June to Septem- 

 ber, golden-yellow, with broad, obcordate, 

 erose petals. The varieties major and 

 Youngi may possibly be a little better 

 than the type ; ambigua has rather pale 

 yellow flowers, at first in corymbs, after- 

 wards in racemes. 



Culture dc. as above. This species 

 may be increased from seeds, and also by 

 dividing the tufts in spring or early 

 autumn. It is also known as CE. 

 serotina.

 petals broadly obcordate, calyx spotted 

 with red. The variety latifolia ormacro- 

 carpa is a fine broad-leaved form. 



Culture dc. as above. As this species 

 often fails to ripen seeds it must be in- 

 creased by dividing the tufts in mild 

 weather in spring; or from cuttings of 

 the yoimg shoots inserted in sandy soil in 

 gentle heat. 



CE. rosea. — A much-branched Mexi- 

 can species about 1 ft. liigh, with oval
