52 ENGLISH BOTANY. 



disk resembling a flattened ring divided into segments by transverse 

 impressed lines. 



With A. Anglica I am unacquainted except from the specimens 

 contained in the Smithian Herbarium, where there are two wild 

 specimens from Sunderland, and a cultivated one from Mr. E-obson's 

 garden — the latter scarcely differing from the normal state of 

 A. arvensis. The wild specimens have the clinanth convex at matu- 

 rity, the palese project between the florets and are rather more 

 pointed than in the var. a ; the pericline is more woolly ; the leaves 

 are much less divided, but not dotted, as erroneously described by 

 Smith. I have specimens of var. a from Crookston, Edinburgh, 

 which have the leaf-segments short and fleshy, approaching those 

 of the so-called A. Anglica. 



Corn Chamomile. 



French, Camomille des Champs. German, Acker IIunds-Kamille. 



Sub-Genus II.— COTA. J. Gay. 



Clinanth hemispherical in fruit. Tube of the perfect florets 

 compressed, winged. Achenes compressed-tetragonal, narrow at 

 the base, truncate at the apex, faintly ribbed on both face and 

 back ; epigynous disk as broad as the achene. 



SPECIES III.— ANTHEMIS TINCTORIA. Linn. 

 Plate DCCXXIII. 

 Reich. Ic. Fl. Germ, et Helv. Vol. XVI. Tab. MX. Fig. 1. 



Perennial. Stem erect or ascending, alternately branched. 

 Leaves sub-glabrous above, somewhat woolly beneath, pinnate 

 (pinnatipartite), with the rachis toothed between the leaflets; 

 leaflets pinnatifid, with the lobes entire or serrate on the outer 

 side and cuspidate. Peduncles striate, densely pubescent, scarcely 

 thickened below the anthodes. Anthodes rather few. Pericline 

 sparingly woolly ; phyllaries unequal, narrowly scarious towards 

 the summit, with a brown ciliated margin. Clinanth hemi- 

 spherical at maturity, with lanceolate acuminate laciniated palese. 

 Kay-florets yellow. Achenes subtetragonal, smooth, with 5 faint 

 strise on each face ; epigynous disk smooth, crowned by an ele- 

 vated membranous margin. 



In fields and stony places. Said to have occurred in the
