tliat plant, an erect, branching annual ; 

 the leaves twice or thrice pinnate, with 

 short bnt very narrow linear segments, 

 and the ilower-heads rather large, on 

 terminal peduncles. Involucral bracts 

 all nearly of the same length, with sca- 

 rious edges. Kay florets white. Re- 

 ceptacle much elongated as the flowering 

 advances, and hollow. Achenes without 

 any border at the top. 



In fields and waste places, in Europe 

 and Russian Asia. Probably diffused 

 all over Britain, but often confounded 

 with the com or the fetid Camomile. Fl. 

 the whole season.

XL CAMOMILE. ANTHEMES 



Herbs, with alternate, much cut leaves, and radiating flower-heads, 

 solitary on terminal peduncles, or in a loose corymb. Involucres 

 hemispherical, with a few rows of bracts more or less scarious on 

 the edges. Receptacle convex or conical, with scales between all 

 or at least the central florets. Achenes angular or striate, without 

 any pappus, or crowned by a minute border. Style nearly that of 

 Senecio. 



A rather large genus, spread over Europe, temperate Asia, and 

 northern Africa ; differing from most Chrysanthemums in habit, and 

 from all in the scales of the receptacle. It has recently been divided 

 into several groups, too technical to be adopted as genera.
