to be contrasted with P. nivalis, its only real allies being our 
own Rocky Mountain and western species, P. Parryi and its 
allies, as I said in the earlier paragraph. 
MERTENSIA LONGIFLORA. Less than a foot high, glabrous 
except the setulose-scabrous upper face of the foliage: lowest 
leaves elliptic-lanceolate, on long and slender petioles, the 
cauline obovate, oval or ovate, only the lower ones with a 
short spatulately tapering petiolar base, the others rounded 
or even cordate at base and closely sessile, the floral bracts 
acutish, all the proper foliage very obtuse, the largest leaves 
2inches long and about 1 inch in breadth: flowers ina rather 
dense strictly terminal and subcorymbose panicle: calyx 
rather large, cleft to near the base, the segments lanceolate: 
corolla about an inch long, with long slender tube and short 
erect narrow-campanulate limb: the almost capillary style 
nearly as long as the corolla. 
Collected in eastern Washington in May, 1893, by Messrs. 
Sandberg and Leiberg, and distributed for M. oblongifolia, a 
species with narrow leaves, and flowers not half as long, the 
calyx-lobes linear. 
MERTENSIA PAPILLOSA. Six to ten inches high, sparingly 
leafy, the leaves oblong, revolute, densely papillose above, 
the low papille bearing a minute short setose hair at sum- 
mit: lower face of leaf smooth and glabrous, margin sca- 
brous: flowers panieled : fruiting calyx short and campan- 
ulate, cleft to the middle, the lobes triangular, their margins 
pubescent, each lobe traversed by a strong carinate mid- 
herve: corolla small and almost tubular, the narrow limb 
with its shallow lobes apparently erect. 
Species apparently peculiar to the parks among the moun- 
tains of Colorado; collected by Geo. Vasey, on Powell’s Ex- 
_ Pedition in 1868, and by Canby, in South Park, 1871. 
E LAGIOBOTHRYS PARVULUS. Habit of P. tenellus and with 
the same pubescence, but plant much smaller, only 3 to 5
