160 Charles V. Piper: Neues aus Flora of the State of Washington. V. 
The following collections have been examined: 
Idaho: On the lower Clearwater River, Sandberg, Heller, & Mae 
Dougal, 75 and 75a, April 30, 1892 (type sheet in U. S. National Her- 
barium, no. 213037); without locality, Rev. G. Ainslee in 1874; Hender- 
son, 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. 
166. Mertensia pulchella glauca Piper, |. c., p. 479. 
Herbage slightly glaucous throughout; leaves narrower, usually 
elliptic, mostly narrowed at base; stems often 2 to 4 from the same tuber; 
corolla tube more slender. 
Specimens examined: Hills west of Wenache, Whited 1010, Mareh 
:81, 1899; type sheet no. 366511 in the U. S. National Herbarium; Badger 
. Mountain, Whited, May 24, 1900. 
This may well prove a distinct species, but in the light of rather 
scanty material is considered too close to M. pulchella. 
167. Mertensia horneri Piper, 1. c., p. 479. 
Stems 8 to 15 cm high, glabrous, solitary or rarely 2 or 3. erect 
from a shallow-seated oblong, black tuber; basal leaves none; cauline 2 
to 5, oblong, obtuse, pale and somewhat glaucous, appressed puberulent 
above, glabrous beneath, sessile, or the lower ones short-petioled, 2 to 
3 cm long; lowest leaves reduced and scarious; inflorescence close; 
-calyx glaucous, parted nearly to the base, its lobes oblong-lanceolate, 
very acute, denticulate-ciliate on the margin; corolla blue, 10 to 12 mm 
long. its tube about twice as long as the calyx; filaments dilated, as 
long as the anthers. 
Specimens examined: Waitsburg, Washington, Prof. R. M. Horner 
-336, April 3, 1897, the type in the U. S. National Herbarium, sheet 
no. 318875; Union County, Oregon, Cusick, 1830, April 13, 1898. 
168. Mertensia pubescens Piper, l. c., p. 479. 
Tufted from a stout vertical] caudex covered with the dead bases of 
old leaves; stems 10 to 15 cm high, leafy to the top; leaves numerous, 
the cauline inclined to be secund, linear or linear-lanceolate, obtuse or 
-acutish, only the midrib evident, 3 to 6 cm long, mostly about 5 mm 
wide, pubescent on both surfaces, the basal ones attenuate into margined 
petioles about as long as the blades, the cauline sessile and but little 
reduced upwards; panicle short, dense, nodding; calyx lobes lanceolate, 
acute, coarsely ciliate, glabrous on the back, a third to a fourth as long 
as the corolla tube; corolla blue, the narrow tube 6 to 8 mm long, one- 
half longer than the campanulate limb; filaments dilated, as long as the 
.anthers. 
Collected near Waterville, Douglas County, by Kirk Whited, 
1214, April 23, 1900, the type sheet in the U. S. National Herbarium 
no. 370326. 
Closely allied to M. amoena A. Nelson and M. bakeri Greene, hut 
distinguished by its narrow more pubescent leaves and longer corollas.
