an Anthemis twice or thrice pinnate, with numerous narrow-linear, 
almost capillary lobes. Flower-heads rather large, on terminal peduncles. 
Involucral bracts with a brown, scarious edge, as in C. Leucanthemum. 
Florets of the ray white, about 7 or 8 lines long; those of the disk 
numerous and yellow. Receptacle convex hemispherical or ovoid, but not 
so conical nor hollow as in M. Chamomilla. Achenes prominently ribbed 
on the inner face, crowned with a minute, entire or 4-toothed border, and 
marked outside near the top with two glandular spots. Chrysanthemum 
tnodorum, Linn. 
In fields and waste places, common in Kurope and Russian Asia, from 
the Mediterranean to the Arctic regions. Extends all over Britain. 7. 
the whole season. A maritime variety, apparently perennial, with the 
leaves rather succulent, has been considered as a distinct species under the 
name of M. maritima, Linn. 
2. M.Chamomilla, Linn. (fig. 525). Common Matricary, Wild 
Chamomile.—Resembles so closely the Anthemis Cotula that it can 
scarcely be distinguished but by the odour and the absence of the scales 
between the florets. It is, like that plant, an erect, branching annual ; 
the leaves twice or thrice pinnate, with short, but very narrow linear seg- 
ments, and the flower-heads rather large, on terminal peduncles. In- 
volucral bracts all nearly of the same length, with scarious edges. Ray- 
florets white. Receptacle 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 dif- 
fused 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.
