238 - THE COMPOSITE FAMILY. [Matricaria, — 
much elongated as the flowering advances and hollow. Achenes 
without any border at the top. 
In fields and waste places, in Europe and Russian Asia. Probably 
diffused all over Britain, but often confounded with Anthemis arvensis 
or A. Cotula, Fl. the whole season. 
. XIV. ANTHEMIS. CHAMOMILE, 
Herbs, with alternate, much cut leaves, and radiating flower-heads, 
solitary on terminal peduncles, or in a loose corymb. Involucres hemi- 
spherical, with a few rows of bracts more or less scarious on the edges. 
Receptacle convex or conical, with scales between all or at least the 
central florets. Achenes angular or striate, without any pappus, or 
crowned by a minute border. Style nearly that of Senecio. 
A rather large genus, spread over Europe, temperate Asia, and 
northern Africa; differing from most Chrysanthemums in habit, and 
from all in the scales of the receptacle. It has recently been divided 
into several groups, too technical to be adopted as genera.

1. A. Cotula, Linn. (fig. 528), " Fetid C., Stink Maguaed —An erect, 
branching annual, a foot high or rather more, glabrous, but sprinkled 
with glandular dots, and emitting a disagreeable smell when rubbed. 
Lower leaves twice or thrice, upper ones once pinnate, with very 
narrow-linear, short pointed lobes, entire or divided. Flower-heads in 
a loose terminal corymb. Involucre slightly cottony, the inner bracts 
scarious at the top. Receptacle convex from the beginning, lengthen- 
ing out as the flowering advances into a narrow oblong shape, with a 
few linear, pointed scales among the central florets. Ray-florets white, 
without any trace of the style. Achenes rough with glandular dots, 
without any border. 
In cultivated ground, and waste places; a common weed all over 
Europe and Russian Asia, except the extreme north. Abundant in 
southern England and Ireland, much less so in the north, and rare in 
Scotland. Fl. all summer and autumn. 
2. A. arvensis, Linn. (fig. 529). Corn C.—A coarser plant than A, 
Cotula, sometimes biennial, often decumbent, more or less downy with 
minute silky hairs, the leafy branches terminating in single flower- 
heads. Segments of the leaves shorter, and not so narrow as in the 
last, the flower-heads rather larger, the bracts of the receptacle usually 
broader, and the florets of the ray have always a style although they 
do not always perfect their fruit. : 
Less widely diffused than A. Cotula, and chiefly south European, but 
extends also over a great part of the Continent. Certainly not very 
common in England or Ireland, and local or rare in Scotland, but so — 
frequently confounded with allied species that its precise distribution — 
is difficult to ascertain. Fl. spring and summer. A maritime variety
