Gen. Char. Calyx (fig. 1, a. and fig. 2.) inferior, of 1 sepal, 
concave, permanent, in from 6 to 12, more or less deep, uniform, 
fleshy, rather sharp-pointed, segments. Corolla (see fig. 1, h.) of 
the same number of petals as the segments of the calyx, and some- 
what larger, spear-shaped, pointed, channelled, equal, spreading, 
withering. Nectary an occasional, very minute, entire scale, at 
the base of each germen, on the outer side. Filaments as many, 
or twice as many, as the petals, opposite to them, but not so long ; 
when more numerous, partly alternate, awl-shaped, spreading. 
Anthers of 2 round lobes. Germens (see fig. 4.) as many as the 
petals, ranged in a radiating circle, oblong, pointed, compressed, 
each terminating in a spreading style, with a blunt stigma. Cap- 
sules (see figs. 5 & 6.) as many as the germens, and of the same 
figure, bursting along their upper or inner margin. Seeds numerous, 
minute, arranged along the inner margin, at each side. 
The 6- to 12-cleft calyx ; the corolla of from 6 to 12 petals ; and 
the 6 to 12 capsules ; will distinguish this from other genera in the 
same class and order.
