Brit, Fl. ed. viii. p. 257. 
Perennial. Rootstock woody, branched, with numerous barren 
shoots ; segments of the leaves very short, cylindrical, fleshy. 
Flowering-stems ascending, short, simple or sparingly corymhosely 
branched towards the apex. Anthodes few. Clinanth of the fruit 
conical, with the breadth and height about equal. Scarious 
margins of the florets generally entire. Achencs broadly-oblong, 
trigonous, with the 2 marginal corky ribs meeting the one on 
the inner face, and leaving scarcely any appreciable space between 
them, and a very narrow one on the outer face. 
Var. a in cultivated ground and waste places. Very common. 
Var. on rocky and shingly seashores, chiefly in the North. 
Stem erect, 6 inches to 2 feet high. Leaves with elongated slen- 
der segments in var. a, shorter and thicker in var. |3. Anthodes on 
long naked peduncles, scarcely thickened below the anthodes. An- 
thodes, including the ray, f to 1J inch across in var. a, 1 to 2 inches 
in var. 3 ; disk slightly convex in flower, yellow, becoming hemi- 
spherical in fruit. Florets of the ray strapshaped, indistinctly 
3-toothed or entire at the apex. Ovary with 2 green spherical 
glands which become pits or fovese on the achenes. Achenes twice 
as long as broad, dark-brown with the ribs whitish, the fovese on 
the outer face nearly black : rarely there are 3 fovea? or 1 by coales- 
cence. Plant bright- rather dark-green, glabrous. 
Var. 3 seems too intimately connected by intermediate forms 
with var. a to be entitled to rank even as a sub-species, though the ex- 
treme forms, such as those from the Scottish coast, are very different 
in habit. The segments of the leaves are much shorter, more fleshy ; 
the flowering-stems much less branched, and generally not so tall; 
the clinanth more conical ; the peduncles more thickened upward ; 
the achenes larger, half as long again as broad instead of twice as 
long as broad, with the corky ribs much thicker and the crown 
larger ; the plant deeper green, and the leaves more shining. 
Scentless Mayweed.

Sub-Genus IV.— MATRICARIA. Linn. 
Clinanth elongate-conical in fruit. Florets of the ray white, 
sometimes absent. Achenes all similar, oblong-cylindrical, with 
o rather slender ribs on the inner face, and the back curved and
