Horkelia fusca, Lindl. 
Potentilla Sweetseri, sp. nov. ? This plant has been referred to 
P. brevifolia, Nutt., but I doubt it. I think there 
are more differences between this plant and P. brevi- 
folia, as described by Torrey and Gray, and Rydberg, 
than there is between P. brevifolia and P. Grayl, Watson. 
I have examined my own plant most carefully, as well as the 
plants of Cusick from the same locality ("Near snow line. 
Strawberry Mts."), as well as his plant _ from the "Wallowa 
Mts , Oregon'; and I find they all agree in the main. 
They all, from Strawberry Mt ., have leaves with 5, or 
even 7, leaflets, not 3, and thestyle near the base is 
covered with knobs or excrescences. It seems to me 
impossible that these knobs should have excaped the 
eyes of Nutt all, Torrey and Gray, and Rydberg, and so, 
I am inclined to believe they must have been lacking 
in Nutt all's specimens. To be sure, these knobs vary 
much. On the Strawberry Mt. specimens they generally 
stand out from the style like the pegs upon an old- 
fashioned hat-rackl In the Wallowa Mt. specimens, they 
are more like mountain ridges, some peaks much more 
prominent than others . 
I take pleasure in naming this species, if it 
prove a new one, for Professor A. R. Sweetser, Head of 
the Department of Botany at the University of Oregon.
