face and on the margins (these are probably the pustulate bases of 
deciduous hairs); root-leaves numerous, oblong or elliptic, mostly 
obtuse, 4—8 cm. long, on somewhat shorter petioles ; the lower 
stem-leaves oblanceolate or broadly spatulate, obtuse, tapering 
into a short petiole, passing into sessile ovate leaves upward ; 
those of the inflorescence crowded, from lanceolate to broadly 
Ovate, acute, 3—5 cm. long: flower-clusters terminal and in the 
axils of the upper leaves, crowded even in the fruit: calyx-lobes 
triangular-lanceolate, subciliate, from 1% to % as long as the tube; 
of the corolla, somewhat enlarged in fruit : corolla tube 5-6 mm. 
long, the very villous ring % its length from the base, the crests 
in the throat and the 10-toothed ring at the base evident ; limb 
funnelform, only slightly spreading, usually exceeding the tube; 
the orbicular lobes less than half its length: filaments inserted in 
line with the crests, membranous, spatulate, as broad or broader 
than the somewhat longer anthers: seeds 2-3 mm. long, ovate, 
coarsely rugose. 
I have sought in vain for any near ally for this truly alpine spe- 
cies. It was collected about the summits of the Medicine Bow 
Mts., Albany county, Wyoming, Aug. 1, 1900. It occurred in 
the rock-slides, mostly in the vicinity of snow banks. The type 
no. is 7870. 
v Mertensia coriacea dilatata 
Very similar, leaves less coriaceous: inflorescence more open 
and less leafy: sepals lance-linear, longer (especially in fruit) : 
filaments shorter, dilated, mostly broader than the anthers. 
This variety is readily distinguished from the species in the 
field but less readily in the dried state when the texture of the 
leaves is not so evident. In herbarium specimens the greater leafi- 
ness, especially of the inflorescence, and the broader sepals of the 
Species in contrast with the opener and less leafy inflorescence and 
the narrower sepals of the variety are the most obvious points 
of distinction. The habitat of the variety is in general the same 
as that of the species and it was secured at the same time; no. 
7844. 
v Mertensia coronata 
Tufted, from large friable roots: stems glabrous, shining, as- 
Surgent, 2-4 dm. long: leaves numerous, large for the plant, 
Smooth below, minutely scabrous above (the hairs very short and 
Curved and sometimes early deciduous from the small pustulate 
€s); the radical on petioles 2-3 times as long as the oblong,
