streams, or on the margin of lakes, particularly in deer or 
buffalo ground, it attains the height of 6 or 8 feet. 
The native tribes that inhabit the interior of North Cali- 
fornia apply the grains to the same purpose as that for 
which we are informed by Nuttall the Indians of the 
Missouri use H. tubeformis. They collect them in the 
autumn, and dry them on heated stones, or in wooden 
troughs with small embers, stirring them with a stick to 
prevent their burning. When dried, they are pounded and 
made into a sort of cake which is not unpleasant. 
Stem erect, as high as a man or higher, hispid. Leaves 
ovate, on long stalks, coarsely serrated, hispid, triple- 
veined. Heads placed upon a hispid peduncle, with two 
leafy bractew at their base. Zmvolucrum squarrose, flat, 
the leaflets ovate, cuspidate, hispid. Florets of the ray 36, 
acuminate. Palee 3-toothed, rather shorter than the florets 
of the disk; these dark purple in the inside of their limb, 
yellow on the outside. Pappus 2-horned.
