feet and, commonly, of eight to fifteen inches from the tip to 

 the lowest flower. The Indian-tobacco lobelia, not so frequent 

 as some of the others, may be identified by its broadly plum- 

 shaped, pointed leaves and its light blue flowers in rather loose, 

 spike-like racemes. Kalm's lobelia, the commonest of all the 

 varieties in Minnesota, is especially abundant in peat-bogs, on 

 banks of lakes and streams and in meadows. It is a slender 

 plant, with light blue blossoms in loose, few-flowered racemes. 

 The flowers are about the size of those of the pale lobelia, or 

 rather smaller, but they are not exhibited in the long slender 

 clusters, characteristic of the other varieties. The fruit of the 

 lobelias is a capsule, usually with two chambers, and to its sur- 

 face the calyx-tube is closely attached.
