458 SYNGENESIA— POLYG.-SUPERF. Anthemis. 



ward. Stafifordshire ; Mr. Pitt. Withering. On Blackheath, 

 and on Hounslow heath in abundance ; also near Lowestoft, 

 Suffolk, and in several parts of Norfolk. 



Perennial. August, September, 



The roots are strong, with long fibres. Stems in a wild state pros- 

 trate, in gardens more upright, a span long, branched, leafy, 

 hollow, round, furrowed, downy. Leaves doubly pinnate, with 

 narrow linear segments, not truly thread-shaped or cylindrical, 

 but rather flat or channelled above, convex beneath ; all acute, 

 often bristle-pointed, a little hairy. Ft. terminal, solitary, ra- 

 ther larger than a Daisy, with a convex yellow disk, and nume- 

 rous, white, spreading or reflexed, rays. The scales of the re- 

 ceptacle do not appear till the florets of the disk are turned to 

 one side, and the innermost are gradually narrowest ; all thin 

 and membranous, not sharp. Cal. with shining membranous- 

 bordered scales, rather downy. Recept. obtusely conical. Seeds 

 very obscurely bordered at the summit. 



Varieties with double^ou;ers, whose yellow tubular florets are, en- 

 tirely or partially, transformed into white ligulate ones, are com- 

 mon in gardens j the discoid variety, destitute of rays, is more 

 rare. The latter perhaps ought to be preferred for medical use ; 

 the double white flowers being now acknowledged to be weaker 

 than those in a natural state. Every part of the plant is in- 

 tensely bitter, and gratefully aromatic, especially the Jloivcrs, 

 whose stomachic and tonic powers are justly celebrated.
