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

2. D. ? occidentalis ; elatus, caule glaberrimo angulato superne ramoso, ramis copiosis 

 subsimplicibus subcorymbosis monocephalis, foliis linearibus rigidis obtusis pilis brevibus 

 simplicibus adpressis utrinque asperis, rameis multo minoribus, involucri hemisphaerici 

 squamis numerosis imbricatis subulatis pubescentibus interioribus sensim majoribus 

 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.

1. Distasis ? concinna ; tota pilis albidis patentissimis canescenti-strigosa, radice

 basi attenuatis radicalibus sublonge petiolatis, involucri foliolis subulatis albidis dorso 

 viridibus, radii flosculis uniserialibus numerosis anguste linearibus disco duplo longioribus, 

 pappo conformi biseriali, serie ext. brevi paleaceo, int. 8-10 setoso. 



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 palea: ; the hairs of the inner row are equal in thickness 

 throughout.
