Leaves pinnate, with 3 or 4 pair of pinnae ; leaflets ovate, 
deeply pinnatifid or bipinnatifid ; all the leaves except the upper- 
most ones (which are bitripinnatifid) stalked, finely pubescent. 
Antliodes corymbose, radiant. Pericline hemispherical ; phyllaries 
-with a blunt keel on the back, the exterior ones lanceolate, with 
the margins narrowly-scarious and pale ; the inner ones oblong- 
strapshaped, white, scarious and lacerated at the summit. Plorets 
of the ray short, flat, white, but much longer than the pericline. 
Achenes cylindrical-prismatic, enlarged upwards, equally 5-ribbed. 
In hedge-banks and waste places. Common, and generally dis- 
tributed, though possibly originally introduced, becoming scarce 
in Scotland. 
England, Scotland, Ireland. Perennial. Late Summer 
and Autumn. 
Rootstock not creeping. Stem 1 to 2 feet high, copiously pani- 
eulately branched in the upper half, sparingly downy. Antliodes 
(including the ray) J to f inch across. Phyllaries more curved 
upwards than in the preceding species, and with a very strong cen- 
tral rib, and destitute of the brown margins of the two first species. 
Ray-florets shorter than the diameter of the disk. Achenes small, 
whitish, sub-pentagonal, all crowned with a membranous border at 
the summit. Plant green ; leaves thin, finely downy, especially 
upon the petioles ; phyllaries slightly downy on the exterior. 
Common Feverfew.
