76 THE WILD PLANTS OF FOREIGN BARLEY FIELDS. 
of which have escaped the preliminary cleaning of the grain, and 
have been removed by the screens of our maltings. 
For the purpose of comparison, I will briefly enumerate the 
wild plants of our own corn-fields before I enlarge on those of our 
neighbours. 
Foremost, at any rate in abundance, we must place the ubiqui- 
tous poppy (apaver), which is inseparable from our ideas of 
corn-fields ; then follow thistles, the corn marigold (Chrysanthemum 
segetum), the chamomile (Axthemis arvensis), the pretty pink- 
petalled cockle (Zichnis Githago), whilst hidden from casual 
observation we shall find the little blue mousetail (JZyosurus 
minimus), the wild pansy (Viola tricolor), and the pimpernel 
(Anagallis arvensis), which, in the colour of its petals, is almost 
unique amongst our wild plants. Very common in some districts 
is the lovely corn-flower (Centaurea Cyanus), but almost unknown 
in others, amongst which the country around Burton must be 
classed. Besides these, we have the charlock (Raphanus Rapha- 
nistrum), the corn crowfoot (Ranunculus arvensis), and, occasion- 
ally, the wild convolvulus (Convolvulus arvensis). These, then, 
are, briefly, the wildlings of our own corn-fields ; let us now turn 
to those of foreign ones. 
Among the seeds which occur in French ates’ is the formi- 
dably spined cremocarp of Caucalis daucoides, one of the 
umbellate family. It is rather common, and is one of the few 
seeds not entirely removed by the process of screening, being only 
separated from the barley during the steeping. It will be readily 
seen that this seed is admirably adapted for dispersion by animal 
agency, armed as it is with such clinging spines. - 
French beans (Phaseolus vulgaris), of many hues, are a striking 
feature, while very numerous are the broken fruits of three or 
four species of the wild radish. The fruit of Ranunculus 
arvensis, or of a near ally to it, is very common, and escapes 
removal by the screens to a great extent. The blue pimpernel 
occurs ; the difference between it and the red variety is easily 
seen on comparing the two specimens. The interesting pods of 
the Medicago genus make their appearance here, but they are
