86 PITTONIA. 
West AMERICAN ASPERIFOLLE.—IV, 
As the result of a prolonged and careful study of our 
North American species of Merrensta, I am convinced that 
nothing properly referable to M. Sibirica is known, at least 
to me, as inhabiting our continent. And as for M. panicu- 
lata, that seems to be subarctic, nothing quite answering to 
it having been found within the United States. Most of 
the specimens in our herbaria bearing one or the other of 
those names may be referred to published species, some of 
which were proposed long ago and then suppressed. Such 
are the following: 
M. cILIATA, Don., originally described as Pulmonaria cili- 
ata, Torr. Ann. Lye. ii. 224. Common in the Rocky Moun- 
tains; excellently defined by Torrey ; its most salient char- 
acteristic being the short calyx, with oval or oblong obtuse 
ciliate lobes. 
M. pratensis, Heller, Bull. Torr. Club, xxvi. 550. Al- 
though Mr. Heller compares this with M. Fendleri, with 
which he says it grows, all its real affinities are with M, 
ciliata, from which I had separated it, in the arrangement 
of sheets in my herbarium, on account of its narrow and 
acute calyx-lobes. But I should not yet have proposed for 
it specific rank. 
M. Franciscana, Heller, l. e. 549. This plant was col- 
lected by myself ten years since, on the slopes of Mt. San 
Francisco. I had noted its peculiarly narrow-tubular corolla 
besides a few other feeble characteristics, but had not thought 
it specifically distinct from M. ciliata.
