According to Hooker the type of Lithospermum denticulatum Lehm. was collected in 
‘Shady woods near the confluence of the Columbia with the sea. Douglas. Mr. Tolmie.” 
It has usually been considered a synonym of Mertensia sibirica 1.., but it probably will 
prove it to be M. platyphylla Heller.

9. Mertensia leptophylla sp. nov. 
Stems glabrous, stout, erect, a meter or more high; leaves ovate, acute, pilose beneath, 
glabrous above, ciliate, very thin, the blades 6 to 10 cm. long, all on margined petioles 1 
to 3.cm. long; inflorescence loose; pedicels with spreading pubescence; calyx parted nearly 
to base, the lobes narrowly triangular-lanceolate, acute, ciliate, smooth on the back; corolla 
blue, about 12 mm. long, the slightly enlarged throat as long as the tube; filaments dilated, 
shorter than the anthers. 
Known only from the Olympic Mountains of Clallam County, the type collected by Elmer, 
no. 2826, July 1900, sheet no. 402139 in the U. S. National Herbarium. The plant was 
also collected on Mount Storm King by Lawrence, no. 359, July 23, 1904. 
10. Mertensia pulchella sp. nov. 
Stems erect, solitary or rarely two, glabrous, 15 to 20 cm. high: tubers shallow-seated, 
simple or fasciculate-branched, black; leaves green, elliptic or ovate, mostly obtuse, 
thickish, glabrous beneath, more or less papillose above, scabrous-ciliate, the lower nar- 
rowed at base and short-petioled, the middle and upper ones ovate, sessile, often half- 
clasping, 2 to 10 cm. long; lowest leaves much reduced, scarious; flowers in a close cluster, 
usually 10 to 15; calyx parted nearly to the base, the lobes oblong-lanceolate very acute, 
denticulate; corolla blue, its tube three to four times as long as the calyx and nearly as 
broad as the ampliate limb; filaments dilated, as long as the anthers; nutlets small, dark 
gray, finely muriculate, attached by a pale and prominent scar, inclosed in the tube of the 
much enlarged fruiting calyx. 
The following collections have been examined: 
Idaho: On the lower Clearwater River, Sandberg, Heller, & MacDougal, 75 and 75a, 
April 30, 1892 (type sheet in U. S. National Herbarium, no. 213037); without locality, 
Rev. G. Ainslee in 1874; Henderson, April 21, 1894; Lake Waha, Nez Perces County, Heller, 
June 2, 1896; Lewiston, Byron Hunter, 11, March 31, 1900. 
All the above specimens are from Idaho, close to the Washington line,so that the species 
doubtless occurs within our limits.
