" THRUM, it does not appear to me to constitute a sufficient 

 " generic character, and it equally exists in Chrysanthe- 

 " MUM indicum, particularly in the single-flowered specimen 

 ** of the Linnean Herbarium." Brown MSS. 



The present is an unpublished species, as yet known 

 only in a double-flowered, and consequently imperfect, 

 state. 



It is said to have been introduced from China by Mr. 

 Barclay ; and to have come to the garden of the Horticul- 

 tural Society (where the drawing was taken in January last) 

 under the name of Pyrethrum chrysardhemifolium. 



Kept in the greenhouse, where it produces a long succes- 

 sion of blossom. 



If, as the case is supposed to be in Chrysanthemum 

 inScum, the palece are an efiect of the luxuriance attending 

 the donble-flowered state, and should prove to be absent in 

 Uie single flower. Chrysanthemum, and not Anthemis, 

 would be the place of our plant. 



For the above account we are indebted to the un- 

 wearied liberality of Mr. Brown, who has taken this op- 

 portunity to account for his retaining Chrysanthemum 

 mdicum in that genus in the 2d edition of the Hortus Kew- 

 ensis, and for not following some of his predecessors in re- 

 ferring the species to Anthemis.
