Illustrated Flora and Manual. Its earliest distinctive name was the 
A. Canadensis B oblongifolia of Torrey and Gray. "Though the 
description is not distinctive, the specimens thus labeled in the 
Torrey Herbarium are fairly conclusive. There are two such lots 
of labeled material with foliage, and one with flowers only. The 
identity of the latter is uncertain, but of the other two, one is straight 
A. oblongifolia as here understood (Princeton, June, 1831); while the 
other bears two branches, one of which, a mere twig in flower only, is 
A. humilis (coll. Gray, Watertown, N. Y., 1833), and the other, which 
is a foliage specimen, is true A. oblongifolia (N. Carolina). The sig- 
nificance of the name oblongifolia is, therefore, fairly clear and the 
name should be applied to our plant. It was transferred to specific 
rank by Roemer in 1847. 
In 1803 Michaux ? described Mespilus canadensis § oligocarpa, with 
habitat “in America boreali," and characterized as “ fruticosa: foliis 
oblongo-ovalibus, basi acutis, subtiliter serrulatis, brevi petiolatis: 
fructibus subsolitariis." This name has usually been interpreted as 
referring to our northern short-petioled few-flowered species, and this 
interpretation is undoubtedly correct, as shown by a photograph of 
the Michaux type made by Prof. M. L. Fernald. The type specimen 
is in the Michaux Herbarium at the Museum d’Histoire Naturelle, 
Paris, and a print of the photograph is in the Gray Herbarium. This 
varietal name of Michaux was not raised to specific rank, however, 
until 1847 (Roemer); meanwhile Tausch ? had published his Pyrus 
Bartramiana in 1838. The identity of this latter plant has always 
been uncertain, though the original description very strongly suggested 
Amelanchier oligocarpa. It was based upon material in the Leibnitz 
garden grown from seed sent by Bartram from North America. 
In the Bernhardi herbarium at the Missouri Botanical Garden there 
are three sheets which bear very old printed labels on which are the 
names Pyrus Neumanniana Tausch, Pyrus Wangenheimiana Tausch, 
and Pyrus Bartramiana Tausch, and through the kindness of Professor 
Trelease the writer has had access to these sheets. "These specimens 
are probably part of the original Tausch exsiccati cited in the original 
description as " Dendroth. exot.-boh. exs.” and, therefore, should 
probably be considered as authentic. The specimen labelled Pyrus
