1. Fetid Camomile. Anthemis Cotula, Linn. 

 (Eng. Bot. t. 1772. Siink Mayiceed.) 



An erect, branching annual, a foot high or rather more, glabrous, but 

 sprinkled with glandular dots, and emitting a disagreeable smell when 

 rubbed. Lower leaves twice or thrice, upper ones once pinnate, with very 

 narrow-linear, short, pointed lobes, entire or divided. Flower-heads in a 

 loose terminal corymb. Involucre slightly cottony, the inner bracts scari- 

 ous at the top. Receptacle convex from the beginning, lengthening out as 

 the flowering advances into a narrow oblong shape, with a few Unear, pointed 

 scales among the central florets. Ray-florets white, without any trace of the 

 style. Acheues rough with glandular dots, without any border. 



In cultivated ground, and waste places ; a common weed all over Europe 

 and Russian Asia, except the extreme north. Abundant in southern Eng- 

 land and Ireland, much less so in the north, and rare in Scotland. Fl. all 

 summer and autumn. 



2. Corn Camomile. Anthemis arvensis, Linn. 

 (Eng. Bot. t. 602.) 



A coarser plant than the fetid C, sometimes biennial, often decumbent, 

 more or less downy with minute silky hairs, the leafy branches terminating 

 in single flower-heads. Segments of the leaves shorter, and not so narrow 

 as in the last, the flower-heads rather larger, the bracts of the receptacle 

 usually broader, and the florets" of the ray have always a style although they 

 do not always perfect their fruit. 



Less widely diffused than the fetid C, and chiefly south European, bu 

 extends also over a great part of the Continent. Certainly not very common 

 in England or Ireland, and local or rare in Scotland, but so frequently con- 

 founded with allied species that its precise distribution is diflicult to ascer- 

 tain. Fl. spring and summer. A maritime variety, with a more spreading 

 stem and thicker leaves, found on the north-east coast of England, has been 

 figiu-ed as A. maritima (Eng. Bot. t. 2370), bat the true plant of that name 

 is limited to the shores of the Mediterranean. The British plant has been 

 since described as a species, under the name of A. anglica. 



3. Common Camomile. Anthemis nobilis, Linn. 

 (Eng. Bot. t. 980.) 

 A procumbent or creeping, branclied perennial ; the flowering branches 

 shortly ascemling, and leafy. Segments of tlie leaves fine, and pointed as in 

 \h& fetid C, but fewer and more compact. Flower-heads on terminal pedun- 

 cles, with white rays. Inner involucral bracts more scarious at the top than 

 in the two last. Scales of the receptacle rather broad, obtuse, and nearly as 

 long as the central florets.
