With our present imperfect knowledge of this plant, it is 

 perhaps necessary to refer it to Anthemis, though in real 

 affinity it will probably be found to approach more nearly 

 to Chrysanthemum Indicum, of which the supposed 

 double-flowered varieties are in like manner generally fur- 

 nished with palece. As that plant, however, in its single 

 state has always a naked receptacle, and some of its 

 double-flowered varieties are constantly, while others are 

 occasionally without palece, in the second edition of the 

 'Hortus Kewensis,' it was continued in Chrysanthemum ; 

 an arrangement which it would not perhaps be necessary to 

 alter, were it even proved that two species have been con- 

 founded under the name of Chrysanthemum Indicum, both 

 of them belonging decidedly to the same natural genus, 

 and to this genus I am inclined to think Anthemis apii- 

 folia, when completely known, may be referred. As to the 

 narrow margo crowning the seed, on account of which our 

 plant has been considered a Pyrethrum, it does not appear 

 to me to constitute a sufficient generic character, and it 

 equally exists in Chrysanthemum Indicum, particularly in 

 the single-flowered specimen of the Linnean Herbarium. 

 Brown MSS. 



For the above account we are indebted to the unwearied 

 liberality of Mr. Brown, who has taken this opportunity 

 to account for his retaining Chrysanthemum Indicum in 

 that genus in the second edition of the ' Hortus Kewensis/ 

 and for not following some of his predecessors in referring 

 the species to Anthemis.
