Ge.\. Char. Involucrum ( common calyx) (fig. 4.) hemisphe- 
rical, imbricated (tiled), of numerous, oblong, close scales, the 
innermost membranous at the margin. Corolla compound ; of two 
kinds of florets ; those of the disk (figs. 2 & 3.) numerous, per- 
fect (having both stamens and a pistil), tubular, regular, level- 
topped, with a 5-cleft limb; those of the ray (fig. 1.) few, some- 
times wanting, tubular at the base, their iimb flat, spreading, 
slightly prominent, 3-cleft, without stamens. Filaments (see fig. 3.) 
in the florets of the disk only, hair-like, very short. Anthers united 
into a cylindrical tube. Germen in all the florets inversely egg- 
shaped, compressed. Style thread-shaped, as long as the stamens. 
Stigmas (see figs. 1 & 2.) a little prominent, recurved, obtuse. 
Seed-vessel none. Seed (fig. 5.) oblong, angular, crowned with a 
slight membranous border, or pappus. Receptacle (see fig. 4.) 
convex, dotted, naked. 
The imbricated, hemispherical calyx ; the 3-cleft, tubular florets 
of the circumference (these florets are sometimes wanting) ; the 
naked receptacle, and the seed crowned with a membranous, entire 
border ; will distinguish this from other genera in the same class 
and order. 
One species British.
