296 THE COMPOSITE FAMILY. 



perhaps not truly indigenous. Fl. summer. A very double variety is now 

 frequent in our flower-gardens. 



4. Scentless Chrysanthemtini. Chrysanthemum inodorum, Linn. 



(Eng. Bot. t. 676.) 



An erect or spreading, branched annual, 1 to li feet high, with the leaves 

 of a Camomile, twice or thrice pinnate, with numerous narrow-linear, almost 

 capillai-y lobes. Elower-heads rather large, on terminal peduncles. Invo- 

 lucral bracts with a brown, scarious edge, as in the Oxeye C. Florets of the 

 ray white, about 7 or 8 lines long ; those of the disk numerous and yellow. 

 Receptacle convex or hemispherical, but not conical as in Matricary. 

 Acheues prominently ribbed, crowned wth a minute, entire or 4-toothed 

 border. 



In fields and waste places, common in Europe and Eussian Asia, from 

 the Mediterranean to the Arctic regions. Extends all over Britain. Fl. the 

 whole season. A maritime variety, witli the leaves rather succulent, and 

 the flowers not so large, has been considered as a distinct species {Pyre- 

 thrum maritimum, Eng. Bot. t. 979). 



X. MATRICARY. MATRICAEIA. 



Habit, foliage, and conical receptacle of Camomile, but the receptacle 

 ■without scales, as in Clu-ysanthemum. Achenes, as in both genera, angular 

 or striate, without any pappus, but sometimes crowned with a minute 

 ' border. 



A very small European, northern Asiatic, and North American genus. 



1. Common Matricary. Matricaria Camomilla, Linn. 



(Eng. Bot. t. 1232. Wild Camomile) 

 Eesembles so closely the fetid Camomile that it can scarcely be distin- 

 guished but by the absence of the scales between the florets. It is, like that 

 plant, an erect, branching annual ; the leaves twice or thrice pinnate, with 

 short but very narrow Unear segments, and the flower-heads rather large, on 

 terminal peduncles. luvolucral bracts all nearly of the same length, with 

 scarious edges. Eay-florets white. Eeceptacle much elongated as the flow-' 

 ering advances. Achenes without any border at the top. 



In fields and waste places, in Europe and Eussian Asia. Probably dif- 

 fused all over Britain, but often confounded with the corn or the fetid 

 Camomile. Fl. the whole season. 



XL CAMOMUjE. ANTHEMIS. 



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

 tary on terminal peduncles, or in a loose corymb. Involucres hemispherical, I 

 with a few rows of bracts more or less scarious on the edges. Eeceptacle 

 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 ; difiering from most Chrysanthemums in habit, and from aU in the
