Gen. Char. Calyx (figs. 1 & 5.) inferior, large, permanent, 
of 1 sepal, tubular; swelling below, 5-cleft above, segments 
pointed. Corolla (fig. 2.) of 1 petal, funnel-shaped, irregular ; 
tube cylindrical, short; limb rather spreading, in 5, deep, blunt, 
rounded segments, one of which is broader than the rest. Filaments 
(fig. 3.) 5, awl-shaped, from some part of the tube of the corolla, 
inclining, somewhat unequal in length. Anthers heart-shaped, 
incumbent. Germen (see fig. 4.) roundish. Style (see fig. 4.) 
thread-shaped, reclining, the length of the longer stamens. Stigma 
(see fig. 4.) capitate. Capsule (fig. 6.) egg-shaped, filling the body 
of the calyx (see fig. 5), blunt, somewhat compressed and marked 
with a longitudinal furrow at each side, of 2 cells, opening trans- 
versely by a convex lid ; receptacles (placentas) (see figs. 7 & 8.) 
oblong, convex, attached to the perpendicular partition. Seeds 
(see fig. 9.) numerous, inversely egg-shaped, curved, dotted, cover- 
ing the receptacles. 
The monopetalous, inferior, funnel-shaped corolla; the capitate 
stigma; and the 2-celled capsule, opening at the apex by a trans- 
verse aperture ; will distinguish this from other genera in the same 
class and order.
