Gen. Char. Flowers (fig. 1.) white or greenish, uniform; those 
in the disk of the umbel frequently sterile. Calyx obsolete, or 
bluntly toothed. Corolla (see fig. 1 .) of 5, roundish, entire, petals, 
with a narrow, incurved point. Filaments (see fig. 1.) 5, thread- 
shaped, spreading, longer than the corolla. Jlnthcrs roundish. 
(icrmen (see fig. 1.) inferior, egg-shaped, striated. Styles (see f. 1.) 
2, very short and thick, divergent, each with a short, conical, rather 
crenulated base (stylopodium). Stomas blunt. Fruit (fig. 3.) egg- 
shaped, contracted at the sides, nearly double. Carpels (see fig. 4.) 
with 5, equal, slender ridges, of which the lateral ones form a 
margin. Channels with single vittce. Seeds gibbous, convex, 
flattish in front. Universal involucrum of few leaves ; partial 
involucrum of many. 
The nearly obsolete calyx ; the roundish petals with a narrow, 
indexed point; the egg-shaped, nearly double fruit; and the 
carpels with 5 slender ridges, and a single villa in each channel; 
will distinguish this from other genera in the same class and order. 
Two species British.
