WEST AMERICAN ASPERIFOLIA. 87 
place of M. ciliata; has a longer calyx, though the lobes are 
as obtuse as in M. ciliata, but they are not ciliate. No such 
hairs as Dr. Kellogg attributes to the species have been 
found by me, or are likely to be discovered. I apprehend 
Dr. Kellogg’s error to have been that of taking a stellate 
hair fortuitously attached to the Mertensia from some other 
plant for one properly belonging to this; or else, and rather 
more probably, certain somewhat pustuliform though flat- 
tened and low protuberances abundant on the leaf-surface, 
were what he saw, and approximately reproduced in his 
figure. 
The two species next succeeding, apparently hitherto un- 
described, are of this same group of rather large moist-land 
species. 
M. POLYPHYLLA. Stems about 14 to 18 inches high, aris- 
ing singly from the branches of a rootstock, apparently 
without radical leaves, but very leafy from near the base to 
the summit, the whole herbage glabrous and very glaucous: 
leaves oblong-lanceolate, mostly about 3 inches long includ- 
ing the short petiole, abruptly acute at both ends, spreading 
or scarcely ascending, neither face callous-punctate, the 
margins obscurely callous-denticulate: flowers mostly sub- 
corymbose at the very summit of the stem: calyx short, the 
ovate-oblong or oval lobes callous-ciliolate: corolla about 3 
inch long, bright-blue, the rather ample campanulate limb 
somewhat longer than the subcylindric tube: obtusely and 
irregularly rugose nutlets well exserted from the calyx. 
In clumps of dwarf willows, at 12,000 ft., near Pagosa 
Peak, southern Colorado, 8 Aug., 1899, C. F. Baker. Related 
to M. ciliata, Don., so common in other parts of the Rocky 
Mountain region, but it is of very different habit, and has a 
callous-punctate leaf-surface and distinctly ciliate leaf-mar- 
gins. Our plant is particularly remarkable for the sim- . 
plieity and the copious leafiness of its stem, the leaves being 
all alike, only that the uppermost are subsessile while the 
rest are petiolate.
