A fine perennial species, native of the banks of the 
S pokan river, in North-west America, whence it was sent 
by Mr. Douglas to the Horticultural Society in 1827. It

It is quite hardy, and grows in common garden soil. 
A perennial, glaucous, very smooth plant. Radical leaves 
spatulate, lanceolate, quite entire, the cauline narrow,
