948 REPORT OF STATE GEOLOGIST. 



LOBELIA L. 



L. cardinalis L. Cardinal Flower. 



Occasional throughout the State, very common in low grounds 

 in the more northern counties. In the height of its flowering 

 season in August it frequently gives its deep red color to acres 

 of lowlands adjoining the smaller inland lakes. In the deeper 

 shade the flowering extends into September.

 (Hessler); Knox (Spillman); Hamilton and Marion (Wilson); 

 (Steuben (Bradner); Vigo and Monroe (Blatchley). 



L. syphilitica L. Great Lobelia. 



The most abundant form in the State. While it reaches its 

 maximum development in low, rich soils, it maintains itself well 

 in dry regions, the adaptations apparently being chiefly a reduc- 

 tion in leaf surface. No especial thickening of the epidermis was 

 observed in sections from a large number of specimens.

Flowering season, August and September. 



L. puberula Michx. 



Usually found in moist, light soil, flowering in July and Au- 

 gust. It is fairly distributed throughout the State in all proba- 

 bility, but definite reports have been received from but few coun- 

 ties.

 sey); Jefferson (Barnes); Hamilton and Marion (Wilson); Monroe 

 and Carroll. 



L. spicata Lam. 



Confined to the northern counties, where it usually occurs in 

 gravelly soil. 



Flowers late in July and August. Forms in dry soil flower 

 from one to two weeks earlier than those in low, wet grounds. 



Reported from Tippecanoe (Cunningham); Cass (Hessler); St, 

 Joseph (Barnes); Lake (Hill); Kosciusko (Coulter); Laporte
