That so remarkable a plant as the present should have 

 escaped the notice of Mr. Menzies and other botanists who 

 had visited the north-west coast of America, I can hardly 

 conceive possible. At the same time, as I am wholly 

 unable to find any description of it, or of a genus that at 

 all corresponds with it, I am under the necessity of intro- 

 ducing it as a plant altogether sui generis. The inflorescence 

 at first sight bears a great similarity to that of some umbelli- 

 ferous plants. The involucre is not very unlike the involucre 

 of the old genus Cheer ophy Hum, and it is so patent and in- 

 cludes so small a quantity of florets, that it has by no means 

 the habit of the flower of the Composite. The foliage resem- 

 bles that of a Cineraria or Cacalia, or, if the leaves be taken 

 separately, of a Tussilago. 



Dr. Scouler of Glasgow, in his late voyage to the north- 

 west coast of America, (of which he has given an interesting 

 account in the latter volumes of Dr. Brewster's Edinburgh 

 Journal of Science,) had the good fortune to find this plant 

 in considerable abundance, both at Fort Vancouver on the 

 Columbia, and at the Straits of Juan de Fuca, considerably 

 to the north of the Columbia, always growing in thick 

 woods. 



I have named this genus from the glands, which are abun- 

 dant upon the stalks as well as on the fruit of the plant.
