 and leaf-like and much longer than the obpyramidal tube. Corolla 

 open-campanulate, 5-lobed. Capsule 3-celled, 3-angled, bursting by 

 mostly irregular longitudinal fissures in the thin spaces between the 

 angles or ribs. {Greek heteros, different, and kodon, bell, the flowers

 9 in. high; leaves roundish, IJ to 5 lines long, sessile, truncate or 

 subcordate at base, sharply toothed, the teeth bristle-pointed and the

 calyx sparsely hispid, its lobes 3 to 5, mostly 3 or 4, when 4 or 5 one 

 or two smaller; flowers solitary; calyx-lobes ovate, foliaceous and 

 sparingly toothed, 1 to 3 lines long; corolla scarcely evident, or the
