times as a weed in cultivated fields. It is also found in rich soil and in 

 dried-up sloughs. 



Lab. to Sask., southw. to Ga., Kans., and La. 



6. Lobelia spicata Lam. McVaugh says : "This is a species with at least 

 five well defined phases," four of which occur in Indiana. A key is given to 

 separate these variations. 



Sinus between the calyx lobes with a conspicuous deflexed appendage 



6a. L. spicata var. leptostachys. 



Sinus between the calyx lobes without a deflexed appendage, rarely a sinus with a 

 short one. 



Lobes of the calyx more or less ciliate with short stiff hairs 



6b. L. spicata var. hirtelUi. 



Lobes of calyx not ciliate. 



Anthers blue; calyx flattish in anthesis; racemes dense, many-flowered; capsules 



short-hemispheric 6c. L. spicata var. originalis. 



Anthers white; calyx roundish in anthesis; racemes few- (10-30) flowered; capsules 

 globose, often somewhat inflated 6d. L. spicata var. campanulata. 



6a. Lobelia spicata var. leptostachys (A. DC.) Mack. & Bush. Map 1976. 

 Infrequent to rare in all parts of the state in dry soil in rather open woods, 

 clearings, prairies, and fallow fields and along roadsides. 



W. Va. to Wis., southw. to Ga., and Ark. ; rare or absent on the eastern 

 Coastal Plain. 



6b. Lobelia spicata var. hirtella Gray. Map 1977. Local in prairie 

 habitats or in marly, springy places in northern Indiana. 



Gaspe Peninsula, southw. to N. Y. and westw. to Ind., and thence 

 northwestw. to Alberta and southw. to e. Kans. 



6c. Lobelia spicata var. originalis McVaugh. This form of the species 

 is very local. My specimens are from dry, gravelly oak slopes in Lagrange, 

 Steuben, and Warren Counties, and from an interdunal flat in Lake 

 County. 



N. B. to Pa., Mich., and Minn., southw. to Ga. and Mo.
