and the points appressed. "! Similarly Wight describes it: “Leaves 
broadly lanceolate . . . or sometimes even obovate to elliptic 
or ellipticcobovate . . . usually serrate from below the middle 
2. . pale or even somewhat glaucous-like below." How 
closely these descriptions of P. cuneata match Willdenow's account: 
“*17, PRUNUS Susquehanae. 
P. pedunculis subsolitariis, foliis obovato-oblongis, subtus glaucis, 
serratis, basi integerrimis. 
Prunus Susquehanae Hortulan. 
Habitat in America boreali." 
The identity of Prunus susquehanae and P. cuneata is further 
shown by the fact that this shrub is well known in eastern Pennsyl- 
vania, as indicated by Porter's statement above quoted, by Long's 
reference to it as “on rocky slopes and summits of the Poconos and 
Kittatinnies, ? by Clute's getting it on a “ Wooded hillside'? of the 
Upper Susquehanna, by characteristic specimens from Lancaster 
County nearer the mouth of the Susquehanna, and by Rafinesque’s 
citation of the original locality of his P. cuneata: “On the mountains 
of Pennsylvania.”
