This species is from the interior, and was sent by Dr Gairdner as collected by Mr Douglas.

2. D.? occidentalis ; elatus, caule glaberrimo angulato superiie ramoso, ramis copiosis 
subsimplicibus subcorymbosis monocephalis, foliis linearibus rigidis obtusis pilis brevibus

lanceolatis albidis fusco-lineatis, radii flosculis sub-40 linearibus purpureis discum duplo 
superantibus, pappo uniseriali ?, ovario hirsute. 
The structure of the pappus seems rather to resemble that of Erigeron, but the capitula are only in a 
young state : the habit, however, allies it more to Diplopappus of De Candolle. 
3. D. leucophyllus. Lindl. in De Cand. Prod. 5. p. 278. 
Of this we have seen no specimen, nor are we certain that it was collected by Douglas, although, as it is a 
Californian plant, and named by Professor Lindley, we think this probable.

Hab. Snake River, below the Salmon Falls, Snake Country. Mr Tolmie. 
Of the genus of this most beautiful plant we are uncertain. The slender stems scarcely a span high, the 
copious foliage, peduncles, and involucres, are every where hoary with harsh white spreading hairs. The 
flowers are about the size of a daisy ; the ray bright blue, in the dried plant, and the disk yellow. The 
outer pappus consists of 5 or 6 lanceolate, short palese ; the hairs of the inner row are equal in thickness 
throughout.
