1912 Wiegand,— Amelanchier in eastern North America 129 
Bartramiana bears also the additional information, “ Aronia praecox 
Neumann, Bartrams Birnstrauch, Nordamerika, Zierstrauch. Bliiht 
in Mai. Reift in August," and is pure unhybridized Amelanchier 
oligocarpa of the most typical sort. Tausch’s name, being the earliest 
specific name, must be accepted for this species, which therefore 
becomes A. Bartramiana (Tausch) Roemer. Only one other synonym 
exists for this species, namely the 4. arguta Nutt. described by Brit- 
ton ! from a sheet so named by Nuttall (collected on Mt. Wachusett, 
Mass.) and from material collected by Eggleston in Vermont (see 
Eggleston in Torreya, 5, p. 107, 1905). Eggleston states that the 
description was mainly taken from his No. 1119, Cedar Swamp, 
Fairhaven, Vermont, and Nos. 1960 and 1964, Blueberry Hill Bog, 
Rutland, Vermont. In the Gray Herbarium there is a duplicate type 
in Nuttall’s handwriting labeled “ Amelanchier * arguta, White Mts., 
N. Hampshire, also on Wachusett Mt., Mass." This and the type 
specimen, which, through the courtesy of the New York Botanical 
Garden, the writer has also seen, are apparently in no way different 
from typical A. Bartramiana. The half-grown fruit is ellipsoid-ovoid 
as in A. Bartramiana when of the same age, and the sepals are fully 
4 mm. long (4-5 mm.), not 2 mm. as Eggleston says. Eggleston's 
No. 1119, a portion of which is also in the Gray Herbarium, does have 
sepals about 2 mm. long and fine teeth on the leaves, but his Nos. 
1960 and 1964 have sepals about 3 mm. long and the teeth as coarse 
as in ordinary A. Bartramiana. No essential difference in the shape 
of the fruit, which is young in all specimens, could be detected between 
the Eggleston specimens and A. Bartramiana. In the light of ex- 
tended experience with the variation in the shape of fruit, size of 
calyx, and coarseness of leaf serration of this species in Newfound- 
land, the writer cannot but feel thatin the present case the slight 
variation in the fruit, on which much emphasis has been placed, is of 
very minor importance. Moreover, there is a possibility that some 
of the Eggleston numbers above cited are hybrids with A. laevis. 
Some hybrids between these two parents have been collected from 
these same Vermont bogs. It seems best, therefore, to consider A. 
arguta a synonym of A. Bartramiana. 
In addition to the above names which have been proposed for the 
East-American species of Amelanchier, the following names are in 
existence and should be briefly considered.
