Gen. Char. Flowers separated ; the outermost irregular, bar- 
ren; inner ones fertile; central mostly neuter, often coloured. 
Calyx 5-toothed, nearly obsolete. Corolla (fig. 2.) of 5 inversely 
heart-shaped petals, with an inflexed point, the outer often radiant 
and deeply bifid. Filaments (see fig. 2.) 5, hair-like, longer than 
the corolla, spreading. Jlnthers rather oblong. Germen (see fig. 3.) 
inferior, egg-shaped, bristly, imperfect in the outermost, as well as 
in the central flowers. Styles (see figs. 2 & 3.) 2, thread-shaped, 
spreading, permanent, dilated at the base, and forming a double 
permanent globe. Stigmas blunt. Floral Receptacle none. Fruit 
(fig. 4.) compressed from the back. Carpels (figs. 5 & 6.) with 
5 primary ridges filiform and bristly, of which the 3 intermediate 
ones occupy the back, and the 2 lateral ones (fig. 6, a.) the inner 
face ; the 4 secondary ridges (see fig. 5. and fig. 6, b.) are equal, 
more prominent, with one row of prickles, which are slightly con- 
nected at the base. Interstices ( channels ) under the secondary 
ridges with single vittce (see fig. 7.) Seed flat in front. Involu- 
crum universal (fig. 1.) and partial, many-leaved. Flowers white 
or pink. 
The separated flowers ; dorsally compressed fruit ; the carpella 
with 5 primary ridges filiform and bristly, of which the 3 interme- 
diate ones are dorsal, and the 2 lateral ones on the plane of the 
commissure ; the 4 secondary ridges equal, more prominent, with 
the prickles in a single row. The channels under the secondary 
ridges with single vittce ; and the flat seed; will distinguish this 
from other genera in the same class and order. 
Two species British. 
DAU'CUS CARO'TA. Wild Carrot. Bird’s-nest. Bee’s-nest. 
Spec. Char. Bristles of the fruit slender. Leaves twice or 
thrice pinnate ; leaflets pinnatifid, with strap-spear-shaped, acute 
segments. Fruit-bearing Umbels concave.
