Obs. The genus to which this plant should be referred is 

 still doubtful. It differs in habit and character both from 

 Amellus and Starkea. It is probably the type of a new 

 genus.

Desc. Root thick, ligneous, descending 1 . Stem 1-2 inches high, densely 

 imbricate with the vestiges of leaves, woolly. Leaves Ungulate, narrow, 

 and lanceolate-spathulate, obtuse, very entire, covered with a silky wool. 

 Flowers pedunculate, large ; the peduncle immersed in the leaves. Invo- 

 lucrum many-leaved, nearly equal; leaflets in a double scries, woolly, 

 about as long- as the disk. Florets of the ray fertile, ligulate, dilated to- 

 wards the extremity, 3-toothed, yellow : of the disk, tubular, perfect, sub- 

 campanulate, yellow, 5-toothed ; border invested with glandular articulate 

 filaments. Anthers simple at the base. Seed very hairy. Pappus 5-7 

 leaved, paleaceous, scarious ; leaflets lanceolate, awned. Receptacle 

 naked. 



Hab. On the highest parts of the Rocky Mountains. 



Obs. I suspect that the present species is distinct from 

 Kunth's ; but I have not had an opportunity of consulting the 

 figure in the JVov. gen. et spec, which he quotes.
