Corydalis (Dicentra) cucularia (Dutchman's Breeches). 

 A very delicate plant, bearing fine-cut leaves, and a 

 scape of about half a dozen white flowers, tipped with 

 yellow. Root, a collection of small solid tubers, enclosed 

 in a common scaly sheath. A native of rich woods, 

 blooming in May or later. Rare in New England. A 

 very curious and ornamental plant. 



Corydalis (Dicentra) Canadensis (Squirrel Corn). A 

 pretty species, native of rich woods. Name given on 

 account of the round, scattered, yellow tubers, which 

 resemble grains of corn. Flowers greenish white, tinged 

 with red, with the fragrance of hyacinths. A pretty plant. 



Corydalis (Dicentra) eximia is a fine, large species, 

 with reddish-purple flowers, resembling the Dielytra. In 

 its wild state it is not, to our knowledge, found in New 

 England, but is not uncommon in gardens. As an orna- 

 mental plant it is most desirable, and increases rapidly 

 in rich soil. 



Corydalis aurea. A very glaucous plant, native of 

 rocky banks ; flowers golden yellow, very showy ; the 

 richness of the color depends, however, on the location 

 of the plant. The plant, unlike all above described (ex- 

 cept C. fungosa), is biennial, and is often lost to culti-
