Dicentra Fumariaceae 483 



2856. DICENTRA Bernh. 



Corolla cordate at the base, the spurs rounded; inner petals conspicuously crested; 

 stem from a flattened orbicular yellowish corm; leaves glaucous beneath, the seg- 

 ments apiculate and more or less rounded at the apex; flowers fragrant 



1. D. canadensis. 



Corolla with two widely spreading spurs; crest of inner petals minute; stem from a 



fleshy, loosely scaly bulb; leaves greenish beneath, sometimes more or less 



glaucous, the segments apiculate and acute at the apex; flowers not fragrant. 



2. D. Cucullaria. 



1. Dicentra canadensis (Goldie) Walp. (Bicuculla canadensis (Goldie) 

 Millsp.) Squirrelcorn. Map 993. This species is found possibly through- 

 out the state, although there are no specimens or reports from the south- 

 western counties. It grows in deep, rich leafmold in well drained soil, 

 usually on wooded slopes. It is much rarer than the next species both in 

 its distribution and in its abundance where found. This and the next 

 species are reported to be poisonous to stock.

2. Dicentra Cucullaria (L.) Bernh. {Bicuculla Cucullaria (L.) Millsp.) 

 Dutch man's-BREECHES. Map 994. Infrequent to frequent throughout the 

 state in deep, rich leafmold and usually in well drained, moist soil. 



N. S. to Minn., southw. to Ga. and Mo. 



2857. ADLIIMIA Raf. 



1. Adlumia fungosa (Ait.) Greene. Climbing Fumitory. This plant 

 was reported from Lake County by Ball in 1884 and from Steuben County 

 by Bradner in 1892. I have been acquainted with it in cultivation for 

 years and I saw a specimen in 1910 in an unpastured woods about 3 miles 

 southeast of Michigan City, La Porte County. I was not prepared to take 

 a specimen but I returned to the same spot a few years later and found 

 the woods heavily pastured and the specimen gone. It was, no doubt, a 

 rare plant in northern Indiana and may yet be rediscovered.
