Hab. Moist soils on the plains of the Multnomah River. Douglas. — Of this I possess but ono, and that 

 an imperfect specimen ; but sufficient to shoAV that the species is very different from any with which I am 

 acquainted, and from any ^rhich I find described in books. The petioles are yery long, 4-0 inches in Icn^^tli, 

 linear, dilated into a sheath at the base, slender, above gradually passing into a lanceolate blade with parallel 

 nerves. The heads are quite spinous with the lonf^ rigid involucres and palese, which much exceed the 

 flowers in length. The calyi: is large, with leafy sepals. The germen covered with white, ovate, acute, 

 somewhat imbricated minute vesicles.
