THE COMPOSITE FAMILY. 



4. Scentless Chrysanthemum. Chrysanthemum inodorum, 

 Linn. (Fig. 508.) 



(Eng. Bot. t. 676. Matricaria, Bab. Man.) 



An erect or spreading, branched an- 

 nual, 1 to 1^ feet high, with the leaves of 

 a Camomile, twice or thrice pinnate, 

 with numerous narrow-linear, almost 

 capillary lobes. Flower-heads rather 

 large, on terminal peduncles. Involucral 

 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, hemispherical, or ovoid, but not 

 so conical nor hollow as in Matricary. 

 Achenes prominently ribbed, crowned 

 with a minute, entire or 4-toothed 

 border, and marked outside near the top 

 with two glandular spots. 



In fields and waste places, common in 

 Europe and Russian Asia, from the Me- 

 diterranean to the Arctic regions. Ex- 

 tends all over Britain. FL the tohole season. A maritime variety, 

 with the leaves rather succulent, and the flowers not so large, has 

 been, considered as a distinct species (Pyrethrum maritimum, Eng. 

 Bot. t. 979).

X. MATRICARY. MATRICARIA. 



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

 without scales, as in Chrysanthemum. 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. 

 (Fig. 509.) 



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



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

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