Perennial. Rootstock woody, branched, with numerous barren 

 shoots ; segments of the leaves very short, cylindrical, fleshy. 

 Flowering-stems ascending, short, simple or sparingly corymbosely 

 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. Achenes 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. 3 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 1^ 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 foveae on the achenes. Achenes twice 

 as long as broad, dark-brown with the ribs whitish, the fove?e on 

 the outer face nearly black : rarely there are 3 fovcaj 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, thougli 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.

Clinanth elongate-conical in fruit. Florets of the ray white, 

 sometimes absent. Achenes all similai% oblong-cylindrical, Avith 

 5 rather slender ribs on the inner face, and the back curved and
