Hab. Common throughout the interior of the Snake Country. Mr Tolmie. 



The specimens from the Snake Country of California consist of flowers only, but those in a most beautiful 

 state. Others, collected by Mr Tolmie himself, to the north of the Columbia, have the leaves and roots 

 quite perfect, and the flowers with capsules almost fully formed. Thus we are enabled to give a more 

 complete account than has yet appeared of this plant, so well known to the Indians of N. W. America, and 

 so much employed by them as an article of food. We may premise, that the account of the foliage and 

 scapes and flower-buds, given in the Botanical Miscellany, is quite correct. But the roots were imperfect, 

 from having been prepared for food ; in which operation not only the fibrous parts are removed, but the whole 

 of the bark also, (dark brown externally, bright red within,) leaving only the nearly pure white fleshy inner por- 

 tion of the root. The flowers are large, the scapes succulent, jointed above the middle, and involucrated with 

 5-7 subulate membranous scales. Sepals about 7, orbiculari-ovate, membranous, spreading, obtuse, pale 

 brown, persistent. Petals 8-10, of a delicate filmy texture and rose colour, 2 or 3 narrow and almost linear, 

 the rest ovate acute, spreading, marcescent, and ultimately twisting around the stamens and pistil, while the 

 sepals retain their form and colour. Stamens numerous, inserted at the base of the calyx. Filaments slender, 

 shorter than the petals. Anthers linear-oblong, yellow, slightly bifid at each extremity, inserted by the back 

 just above the fork. Ovary globose-ovate, finely striated, and contracted at the base into a very short thick 

 stipes. Style persistent, but apparently jointed with a dark line a little above the base, aud then dividing
