 — The first I knew of this plant was from Chamisso, who had the kindness to communicate to me an Una- 

 laschka specimen, imder the name of Artemisia matricarioides of Lessin^ in the Linnrea, So little does it 

 accord in habit, however, with Artemisia, that I was not surprised to find the able Author had removed it 

 from that Genus, in his subsequent work, the " Synopsis Generum Composltarum." With Tanacetum I fear 

 it has little more affinity, either in foliafje, indorescence, or in the receptacle or rachis. The habit is 

 altog^ether that of a Cotula, or of an Anthemis without ray; but it is probably sui generis, Lessino^ considers 

 the rachis or receptacle to be destitute of scales or bracteas, but I find the extremity only free from scales, 

 the rest is evidently furnished with them.
