with a more spreading stem and thicker leaves, formerly found on the 
coast of Durham, has been figured as A. maritima, Linn., but the true 
plant of that name is limited to the shores of the Mediterranean. ‘The 
Durham plant has been described under the name of A. anglica, Spr. 
3. A. nobilis, Linn. (fig. 530). Common C._—A procumbent or creep- 
ing, branched perennial; the flowering branches shortly ascending, and 
leafy. Segments of the leaves fine, and pointed as in A. Cotula, but 
fewer and more compact. Flower-heads on terminal peduncles, with 
white rays. Inner involucral bracts more scarious at the top than in 
the last two species. Scales of the receptacle rather broad, obtuse, and 
nearly as long as the central florets. 
A native, apparently, of western Europe, and chiefly of sandy pastures 
near the sea, but, having been long cultivated, it has established itself 
in so many places that its precise area cannot well be made out. Evi- 
dently indigenous in southern England and Ireland, but decreases 
rapidly northward, and not a true native of Scotland. Fl. summer and 
autumn. 
4. A. tinctoria, Linn. (fig. 531). Yellow C.—This has much the 
habit and aspect of A. arvensis, but is usually a taller plant, and more 
downy, the leaves less divided, with pinnatifid or toothed segments, 
the flower-heads rather larger, and the rays of a bright yellow. 
In cultivated and waste places, in central and eastern Europe and 
Russian Asia, abundant in Denmark and Eastern France, but scarcely 
farther west. Jn Britain, it has been found on ballast heaps in some 
of the eastern counties of England. Fl. end of summer. 
XV. ACHILLEA. ACHILLEA. 
Herbs, mostly perennial, with alternate, much divided, or rarely 
simple leaves; the flower-heads rather small, in a terminal corymb, 
with white or pink rays, and ‘a yellow disk. Involucres ovoid or hemi- 
spherical, the bracts imbricated, only slightly scarious on the edges. 
Receptacle small, not convex, with scales between the florets. Achenes 
without any pappus. Style nearly that of Senecio. 
A considerable European, North American, and Asiatic genus, divided 
by modern botanists into two sections or genera, represented by the 
two British species, but separated by very trifling characters.

1. A. Ptarmica, Linn (fig. 532). \Biaecetiore —Rootstock perennial 
and creeping. Stems erect and glabrous, 1 to 2 feet high, nearly 
simple. Leaves rather broadly linear, and regularly serrate. Flower- 
heads few, in a loose terminal corymb. Involucres hemispherical, 
slightly cottony, smaller than in Anthemis, but much larger than in A. 
Millefolium. Florets of the ray generally from 10 to 15, short, broad, 
ae white ; those of the disk numerous, interspersed with small linear 
scales, 
In moist, chiefly hilly pastures, in northern and central Europe and 
Asia, becoming a mountain plant in southern Europe, yet not extending 
to the Arctic regions. Common in Britain. FU. summer, rather late.
