» This species differs from Prunus me.icana polyandra Sargent, to which it is similar in general appear- 

 ance, in its thicker prominently reticulate-veined leaves, shape of the fruit pit, and in the long white hairs 

 on the under side of the leaves. 



Prunus reverchonii Sargent (Oklahoma and Texas), Prunus venulosa Sargent (Texas), Prunus geniculata 

 Harper (Florida), and Prunus tt.ana Dietrich (Texas) are shrubby species. 



71 Specimens collected near Monteer, Shannon County, Mo., and at Marshall, Tex., are believed to 

 represent this variety. The flowers appear to be distinctive in the large number (36) of long stamens they 

 bear (Sargent). 



"* Formerly confused with Prunus americana Marshall, differing from this and other native species in 

 its thick reticulate-veined leaves and in the shape of the fruit stone.
