Gen. Char. Involucrum ( common calyx) (fig. 1.) slightly con- 
vex, closely imbricated, with several oblong, nearly equal, mem- 
branous-edged scales. Corolla (fig. 2.) compound, radiant; florets 
of the conical disk (see fig. 3.) numerous, perfect, tubular (see fig. 4.), 
with 5 equal spreading segments; florets of the ray numerous, 
strap-shaped, spreading or reflexed, blunt, with 3 terminal teeth 
(see fig. 5). Filaments (see fig. 6.) 5, in the tubular florets only, 
hair-like, very short. Anthers (see fig. 6.) in a cylindrical tube. 
Germen (see figs. 5, 6, & 7.) in all the florets inversely egg-shaped, 
angular. Style (see figs. 6 & 7.) thread-shaped, not prominent. 
Stigmas (see figs. 4—7.) spreading, blunt. Seed-vessel none, but 
the unchanged expanding calyx. Seed (figs. 8 & 9.) in all the 
florets inversely egg-shaped, angular, without any border or crown. 
Receptacle (see fig. 10.) naked, almost perfectly cylindrical, hollow. 
The nearly flat involucrum , with closely imbricated, nearly 
equal, membranous-edged scales ; the numerous, strap-shaped 
florets of the ray ; the nearly cylindrical, naked receptacle ; and 
the seeds without cither pappus or border; will distinguish this 
from other genera in the same class and order. 
It differs from Anthemis (t. 328.) in the receptacle being naked, 
not chaffy. 
One species British. 
MATRICA'RIA CHAMOMI'LLA. Wild Chamonr Bitter 
Chamomile. Corn Fever-few. 
Spec. Char. Leaves smooth, twice-pinnatifid, the segments very 
narrow, strap-shaped. Involucrum nearly flat, its scales bluntish.
