 flowers. Calyx-tube turbinate, hemispheric or ovoid, adnate to the ovary. 

 Corolla-tube straight, oblique, or incurved, divided to the base on one side, 

 2-lipped in our species, the lobe on each side of the cleft erect or recurved, 

 turned away from the other 3 which are somewhat united. Stamens free 

 from the corolla-tube, monadelphous, at least above, 2 or all the 5 anthers with 

 a tuft of hairs at the tips, 3 of them usually larger than the other 2, all united 

 into a tube or ring around the style. Ovary 2-celled, the 2 placentae many- 

 ovuled; stigma 2-lobed or 2-cleft. Capsule loculicidally 2-valved. [Named 

 after Matthias de L'Obel, 1538-1616, a Flemish botanist.] About 250 species

 tuberculate. BAHAMA LOBELIA.
