130 AMONG THE WILD FLOWERS. 
This oil gives the aromatic odour and property 
peculiar to most of the plants of this Order. 
The seed itself lies within this outer case, and 
is tasteless. The best method of observing the 
stripes is to cut through the mericarp horizon- 
tally, when the position of the oil-tubes, or 
vittze, is seen by dark dots, from which the oil 
itself exudes. The entire fruit is called a cvemo- 
carp; each of the 2 seed-like valves into which 
it divides is a mericarp, the central column 
or stalk, from the divided parts of which the 
mericarps hang, is called the carpfophore. This 
carpophore is also designated the aazs. 
This description is that of one of the most 
common forms of the fruit; there are various 
other shapes, but all following the same rule of 
structure. Daucus, Carrot, has the fruit prickly ; 
the fruits of Pastznaca and Hleracleum have 
a dilated flat margin; those of the Angelica 
Tribe are much compressed, with a double 
wing on each side; these variations, and the 
various position and number of the stripes and 
ridges, are the features which determine the 
different species. 
There is another plant similar to the Wild 
Chervil, namely, Cherophyllum temulentum,
