Specimens examined: Mount Carlton, Kreager 190. 



7. Mertensia platyphylla Heller, Bull. Torr. Club 26: 548. 1899. 

 \ Litfiospennum denticulatum Lehm. Aspcr. 2: 294. 1818. 



Type locality: Montesano, Wasliington. Collected by Heller. 



Range: Western Washington. 



Specimens examined: Montesano, Heller 3872; New London, Laml 1168; Skokomish 

 River, Kincaid, May 16, 1892. 



Zonal distribltion: Humid Transition. 



According to Hooker the type of Lithospermum denticulatum Lehm. was collected in 

 "Shady woods near the confluence of the Columbia witli the sea. Douglas. Mr. Tolmie." 

 It has usually been considered a synonym of Mertensia nibirica L., but it probably will 

 prove it to be M. platyphylla Heller.

 Zonal distribution: Canadian. 



9. Mertensia leptophylla sp. nov. 



Stems glabrous, stout, erect, a meter or more high; leaves ovate, acute, pilose beneath, 

 glabrous al>ove, 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 ba.se, the 1oIh»s 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. 2820, 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 piilchella sp. nov. 



Stems erect, solitary or rarely two, glabrous, 15 to 20 cm. high; tubere 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 amphate 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, 

 Bev. 6. Ainslee in 1874; Henderson, April 21, 1894; Lake Waha, Nez Perces County, Heller, 

 June 2, 1890; 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.
