FUMITORY FAMILY. Fumariacc*. 



alights on the flower, forces its head between the inner 

 petals, and gathers only the pollen with its front feet ! 

 Such a pendulous position as the flower compels is ex- 

 tremely difficult for insects other than bees to maintain, 

 Butterflies therefore visit the flower with less success 

 than bumblebees. Pieris rapce (Cabbage butterfly, white), 

 Papilio ajax (buff and black, crimson spots), and Danais 

 archippus (the Monarch, black-and-tan) are common 

 visitors ; so are the little long-tongued flies of the tribe 

 Bombylius (the beelike flies). Flowering stem 5-9 inches 

 high. In thin woodlands and on rocky slopes from N. 

 Eng., south to N. Car., and west to Neb., S. Dak., and 

 Mo. The name from the Greek, meaning twice-spurred.

Dicentra exima is a tall rare species, with less finely 

 cut leaves, large and smooth, and with narrow magenta- 

 pink flowers. Sometimes cultivated. 1-2 feet high. 

 Rocky slopes. Western N. Y. , south to Ga. and Tenn. , 

 along the mountains. 



Pale Cor delis ^^ s * s another conspicuously delicate 

 Corydalis wild flower of spring. Its relationship 



sempervirens with Dicentra is manifested by the pale 

 Pale pink foliage and the attenuated sacklike blos- 



ay-Augus gom . j n ^ ew jEngland it seems almost to 

 supplant Dutchman's Breeches. The pale or whitish 

 green leaves are compound, and cut into ornamental 

 segments which are generally three-lobed. The pale 

 crimson-pink, or sometimes magenta-pink, slightly 

 curved corolla is half an inch or more long, somewhat 

 round at the top (which is really the bottom), and two- 

 flanged at the bottom or mouth, which is golden yellow 

 The leaves are scattered alternately on the plant-stem at 

 the branching summit of which are groups of rarely
