 STN. Lobelia (of Presl). OBD. Campanulacew. A large 

 genns (nearly 100 species) of very beautiful, glabrous,

 corolla; peduncles one- flowered, ebracteate or minutely 

 bibracteolate, axillary or forming clustered corymbs or 

 loose racemes at the tips of the branches. Leaves alter- 

 nate, rarely whorled, entire or denticulate, rarely incised- 

 toothed or pinnately lobed or dissected. The introduced 

 species are described below. They succeed in a light, 

 turfy loam, and peat, and are propagated by cuttings.

 perennials.

 having the limb of the corolla almost white. A garden form, 

 raised in the gardens of the King of Belgium, in 1850.
