The Shore Plum, here figured, occurs on the sands of the 
Atlantic sea-shore from New Brunswick to Virginia, and is 
also met with at the head of Lake Michigan, Chapman 
indeed (Flora of the Southern United States, ed. 3, p. 131) 
records it from Alabama; the basis of this record is, how- 
ever, a very imperfect specimen collected by Buckley in 
the Alleghany Mountains, and Sargent (Sylva of North 
America, vol. iv. p. 28) is probably justified in concluding 
that, as no other trace of P. maritima has been met with in 
this now well-explored region, the specimen obtained by 
Buckley merely represents a form of P. alleghaniensis, 
Porter. The nearest ally of P. maritima is P, Gravesii, 
DecemsBer, 1909,
