 as in Dicentra. 



A rather large genus, of wide geographical distribution, most abundant in the Old World, only 

 a single and a rare species known in California. Two others are not unlikely to occur on tlio nortli- 

 ern border, viz. 



C. AUitKA, Willd., var. ocoidentai.is (otherwise called C. montana), Engelm., a low biennial 

 species with golden yellow blossoms.
