suggests this species; especially that part in which the flowers are 
described as small, in close stocky racemes, with short stocky calyx- 
lobes which are “reflexed-curled,” and in which the plant is said to 
grow in colonies forming a thick hedge. The teeth of the leaves are 
described as coarse, which would indicate that it belonged to the 
present group. In reply to a letter in regard to the type, Blanchard 
writes that the specimens distributed by him may be taken as typical. 
The Blanchard specimens named A. erecta in the Gray Herbarium 
are quite diverse, both as to size of flowers and venation of the leaves, 
as well as to other details of general appearance. None of them from 
Vermont, the type region, have exactly the same leaf and inflores- 
cence as our specimens of the dwarf species from elsewhere. The 
broadly oval, coarsely toothed leaves, mentioned in the description 
and seen in the specimens, suggest A. sanguinea, as do also the long 
pedicels and moderately long sepals. Except in one specimen, the 
petals also are somewhat longer than is typical of our species. The 
more irregular veins of Blanchard’s plants suggest A. stolonifera or 
A. laevis, while the small flowers also suggest A. stolonifera. The 
height given (4-12 ft.) is greater than is to be found among typical 
plants of the present species farther westward. If Blanchard’s North 
Westminster plants were of this species, they would extend the eastern 
range slightly, since we have no other specimens from east of Troy, 
New York, and northern Lake Champlain. All things considered, 
therefore, the name A. erecta seems of too questionable application 
to warrant its adoption for our plant. Itis thus desirable to give the 
species a new name, and A. humilis has been chosen because of the 
low dwarf habit of the shrub. 
In 1818 Nuttall! described Aronia alnifolia with a range given as 
from Ft. Mandan to the Andes, but otherwise no definite locality was 
cited. The description calls for a small.leaf, rounded and toothed 
near the summit, somewhat acute at the base, and smooth at maturity. 
This might apply to a small leaved specimen of what is here called 
Amelanchier florida, but the leaves in that species are almost never 
acute at the base. It might, also, be one of several of the small- 
leaved western species recently segregated by Greene and others. 
In the Torrey herbarium there is a small fragment bearing four leaves 
and a bud, which bears the label, in Nuttall’s hand, “ Amelanchier
