(A) Spiked Lobelia (Lobelia spicata) is a small 
flowered species having a simple leafy stem from 1 to 4 
feet in height. The leaves vary greatly in shape from 
lance-shaped to oblong, and decrease in size rapidly as 
they approach the flower spike. The small, pale blue- 
violet flowers are set in short smooth calyces. The 
upper lip of the corolla has two small lobes and the 
lower one is divided into three, larger, spreading ones. 
It is commonly found in dry, sandy soil from N. S. to 
Manitoba and southwards. 
(B) Indian Tobacco (Lobelia inflata) is the most 
common of the Lobelias; it is found growing everywhere 
in either sandy or moist soil, in woods or in fields. The 
alternating leaves are pointed-oval and sparingly wavy- 
toothed; the lower ones are quite large, while the upper 
ones are very small. The simple stem is stout and 
quite hairy; it grows from 1 to 2 feet in height. The 
little blue-violet flowers are barely one quarter inch 
long, each seated in a large, smooth inflated calyx. 
The flower calyces enlarge after the corollas have 
withered away, and form round seed pods.
