BORAGE FAMILY 315 



Moist places on rocky slopes, g-enerally in lava soil, 4500 to 6500 feet: Sierra 

 Nevada (east side) from Sierra Co. to Modoc Co. North to Idaho, east to Utah. 

 May-July. 



Locs. — Loyalton (4 mi. ne.), Sierra Co., Slebbins 4" Jenlcins 2124; Lassen Peak (near), 

 Levimon: Forest dale, sw. Modoc Co., M. S. Baker; Emigrant Sprs., cent. Modoc Co., E. M. Austin; 

 Goose Lake Valley, Modoc Co., Austin 4' Bruce 22G0 ; Jess Valley, Warner Mts., Steffen 29a;

 partial or general presence or complete absence, but such forms have no geographic significance 

 and are often mixed in single collections.

Mertensia bella Piper, Proc. Biol. Soe. Wash. 31:76 (1918), type loc. Horse Pasture Mt., 

 Lane Co., Ore., Peck 5811. Stem slender, rather freely branched, 1 to 1% feet high, arising from 

 a tuberous root; leaves ovate, the uppermost opposite; corolla blue, campanulate, 3 lines long. — 

 Ore.: Grayback Mt., Siskiyou Mts., Applegate 8751 (near California line). 



3. M. longiflora Greene. Stem erect, simple, 4 to 6 inches high, arising from 

 a shallow tuberous root ; herbage glabrous or nearly so, the upper side of the leaves 

 scabridulous ; leaves 1 to 2i/2 inches long, the blades oblong-ovate or spatulate- 

 obovate, mostly obtuse, the upper sessile, the lower narrowed to a short broad petiole 

 or subsessile; panicle mostly drooping; corolla bright blue, 7 lines long, the tube 

 long and narrow, the throat very short (1 to 1^/4 lines long) but longer than the 

 very short lobes. 



Well-drained soil of open hillsides, 5000 to 7000 feet : Modoc Co. North to 

 southern British Columbia and western Montana. Apr.-June. 



Geog. note. — The center of distribution of Mertensia longiflora, a very distinct species, is 

 probably in Idaho. Thence it ranges south through eastern Oregon (Cusick 1830) into Modoc 

 Co., California (near Fort Bidwell, Gilman 583, and South Warner Mts., L. S. Smith 1083, out- 

 lying localities, representing the southernmost known stations).
