reasons for including the varieties of this group with the great com- 
pany of ortulana hybrids and for rejecting the supposition of a 
Prunus rivularis derivation. Further investigation confirms me in my 
earlier view, but leads me at the same time to the belief that Munson 
was correct in identifying the Wayland varieties with Scheele’s P. 
vivularis. In other words, I am convinced that P. rivularis Scheele is 
nothing more than one of the more distinct subdivisions of the multi- 
form hortulana group. A part of the argument for this conclusion is 
already set forth in the article referred to, giving the geographical 
origin of the varieties of the Wayland subgroup. That is, such varie- 
ties as Golden Beauty, coming from the range of the supposed P. 
rivudaris, and almost certainly identical with that supposed species, 
are conspicuously like such other varieties as Cumberland, Garfield, 
Kanawha, Leptune, Missouri Apricot, Moreman, Sucker State, and Way- 
land, which have originated respectively in the states of Tennessee, 
Ohio, Kentucky, Arkansas, Missouri, Kentucky, Illinois, and Kentucky. 
All these varieties agree fairly well with Scheele’s description of P. 
rivularis. If there were such a species it would be almost impossible 
to exclude all these varieties, and quite impossible to include them all, 
because we cannot suppose a distribution of P. rivularis through the 
States named. 
Moreover, an examination of the material in herbaria passing 
as Prunus rivularis seems to support this conclusion. Scheele founded 
his P. rivularts upon Lindheimer’s 389 in Fxsiccata Flora Texana. 
Through the kindness of the curator I have been enabled recently to 
€xamine the material in the National Herbarium, including a specimen 
of Lindheimer’s 389. This specimen is not an extra good one, but 
Shows flowers, fruit, leaves, and some small twigs, giving most of the 
characters fairly well. It is a trifle Chicasaw-like in general appear- 
ance, but answers nicely in every particular to Bailey’s description of 
P. hortulana. Xt also looks most like Golden Beauty and some other 
varieties belonging distinctly to the Wayland group. This specimen 
Was collected in 1846, and it seems strange that a greater number of 
Specimens have not been collected since then. 
Another specimen in the National Herbarium is 187 of Elihu 
Hall, and was collected at Dallas in 1872. This one is still more easily 
referred to the hortulana group. In fact it conforms much more 
readily to our ideas of P. hortulana as represented in literature and in 
herbarium materia] than do many of the cultivated varieties which
