Secondary leaflets (segments) of tlie leaves reduced to large 

 teeth, fleshy. " Clinanth flat " (Sm. & ]3ab.). 



In cultivated fields, by roadsides, and in waste places. Rather 

 rare, but generally distributed, except in the North of Scotland,

England, Scotland, Ireland. Annual. Late Summer

Stem much branched from the base, where it divides into 

 numerous decumbent or ascending rarely erect branches to 18 

 inches long ; primary branches simple in small specimens, slightly 

 and irregularly branched in large ones. Leaves resembling those 

 of A. Cotula, but the segments are broader and shorter, so tliat the 

 leaves ap[)ear less finely divided ; sometimes the segments are very 

 short and fleshy. Anthodes 1 to 1^ incli across. 



This may readily be confounded" with A. Cotula, but the stems
