Trachelium ceruleum, a south Kuropean plant of early cultivation in 
our flower-gardens, belongs to the same family; and the Australian 
Goodenias, Scevolas, and other allied plants, often seen in our greenhouses, 
form a small family, which may almost be considered as a tribe of Cam- 
panulacee.. — 
I. LOBELIA. LOBELIA. 
Flowers in terminal racemes, usually leafless or nearly so. . Corolla very 
irregular, more or less cleft on the upper side, with 5 lobes usually forming 
two lips; the 2 upper lobes smallest, and erect or recurved; the 3 lower 
ones spreading, and less deeply divided. Anthers united in a tube round 
the style, often hairy, or the two lower ones bearded at the top. 
A numerous genus, widely spread over the globe, and yet wanting in 
the greater part of the continent of Hurope and northern Asia. Several 
North American species, with brilliant scarlet or purple flowers, as well as 
Cape or Australian ones with blue flowers, are much cultivated in our 
gardens.
