Hab. Canada. {Kalm, ex Willd.) Pursh.—l am unacquainted with this plant, except it be the same 

 as the following, to which Willdenow says it is « closely allied, but that it differs in the stem, nearly the 

 height of a man, beingf rough, glabrous below."

Hab. North-West coast of America, and in the interior about the Columbia, and to the south of that river. 

 — I possess no native specimen of this plant. " It is nearly related to H. tubcpformis, from which," according to 

 Mr. Douglas, " it differs iu not having the leaves cordate at the base, or the peduncle fistulose and thickened. 

 The native tribes that inhabit the interior of North California, apply the grains to the same purpose as that 

 for which we are informed by Nuttall the Indians of the Missouri use H, tub(£fonnis. They collect them 

 in the autumn, and dry them on heated stoves, or on wooden troughs, \vith 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." Douglas.

Hab. Common on the low moist soils of the plains of the Columbia, near the ocean; and in the vallies 

 of the Rocky Mountains.* Douglas. — Two specimens only of this remarkable plant are in my possession, 

 and in both, the flower is imperfect. The stem is three feet high, simple, striated, and hispid. Leaves 

 remote, somewhat hairy, lanceolate, or linear-lanceolate, very clammy, and as if varnished, especially beneath ; 

 the lower ones a foot long, including their petiole, which is about eqxial in length to the blade; upper ones 

 smaller and sessile. Peduncle elongated, terminal, single-flowered. Flower large. Involucres of numerous, 

 imbricated, broadly lanceolate, strongly ciliated scales. The ray, if auy, is not present in my specimens. 

 Tubular florets numerous, yellow. Achenium with a short lacerated margined crown, and one or two long 

 and strong persistent slightly downy spines. Mr. Douglas had marked it ** Wedelia ?"

• Since the above was written, I find the same plant in Capt. Beechey's Collection, gathered at San Francisco 

 in California, by Messrs. Lay and Collie. There the ray is present and large, though consisting of few florets. 

 The leaves are less glutinous than in the Columbian specimens.
