1912] Wiegand,— Amelanchier in eastern North America — 127 
alnifolia R. Mts. a low shrub. The racemes long and erect." On it 
Dr. Gray has written, “ Nuttall must mean his A. pumila for this.” 
'Those leaves are about 22-27 mm. long, are rounded at both ends or 
but slightly cuneate at the base, and there is some slight indication 
of tomentum still remaining. In the Herbarium of the Academy of 
Natural Sciences at Philadelphia there is a fragmentary specimen from 
the “Columbia River" labeled Amelanchier alnifolia Nutt. in Nuttall's 
handwriting. The summit of the ovary in this specimen is glabrous 
and the specimen may be A. Cusickii Fernald. At least, we are not 
warranted in saying that it is the same as the plant east of the Rocky 
Mountains. The writer sees no way of deciding what either of these 
plants really is, or what Nuttall had in mind when describing Aronia 
alnifolia. Unless more material named by Nuttall can be found, 
it seems impossible to make use of his name. "The first name that 
does definitely apply to our present species is the Amelanchier florida 
of Lindley,! published in 1833. This was accompanied by a fine 
colored plate and a long description with notes. Both the plate and 
the description, but more especially the former, fit our plant very well 
indeed. "There seems little if any doubt that Lindley had in mind 
the plant here called A. florida, and the Lindleyan name is, therefore, 
adopted for the plant under discussion. 
'The stoloniferous coastal species of dry soil has never received a 
distinctive name. It has passed variously as Amelanchier oblongifolia, 
A. spicata, and A. ovalis; but the first of these is a quite different plant, 
and the other two names have already been shown not to apply to any 
species known at present. In recent years it has formed the basis of 
the A. spicata of Britton’s various works. Since no other valid name 
exists for the species it may be called A. stolonifera because of its 
peculiar habit. 
The swamp species with alder-like habit has been very generally 
confused with other species. It seems to have constituted all of 
Ashe's? *obovalis" and a part also of Michaux's? It was the Pyrus 
ovalis of Bigelow and Pursh, and the Aronia ovalis of 'Torrey’s Flora 
of the Northern and Middle States. It constituted a part of the 
Mespilus arborea of Michaux, and of the Amelanchier intermedia of 
Britton’s N. A. Trees, as well as a part of the A. Botryapium of Britton's
