Hab. Common in open Piue-woods, on the North-West coast of America. Douglas. — The single speci- 

 men I possess of this plant has the flowers so far advanced, that the stamens and petals have fallen ; and the 

 description given by Pursh of P. Lewisii is so unsatisfactorj-^, that I cannot be sure it is the same. Our 

 plant has the branches slender, twiggy, brown, spreading horizontally, quite glabrous. The leaves are ovate 

 or ovato-oblong, acute or acimiinate, entire or slightly toothed, three or five nerves aiosing from very near 

 the base which is woolly beneath, at the axils of those nerves. Flowers ternate at the extremity, and in 

 the axils of the upper pair of leaves are two single-flowered pedicels, one in each axil. Calyx-segments ovato- 

 lanceolate, acuminate, very woolly at the points. Free portion of the germen glabrous ; Style 3- or 4-cleft.

Hab. Plains of the Red and Assinaboyne Rivers, and banks of the Saskatchawan. Dottglas, Dr. Rich- 

 ardson, Drummond.—\i I am correct in refening this to the plant of WiUdenow — and it well agrees with 

 th;it author's description, so far as it goes — the segments of the corolla are remarkably long and attenuated, 

 and the female flowers of rare occurrence. Of the six specimens in the Collection, possessing numerous 

 racemes, from two to five or six inches long, of male flowers, only one raceme has at its base (as "WiUdenow
