NATIVE AMEEICAE" SPECIES OF PRUNUS. 71 



scribed by Koehne under the latter name is P. americana, but since 

 the name P. californica is given only in synonomy it is not a valid 

 publication. 



Prunus coccinea Raf., 1817, Fl. Ludov., p. 135. 



E,afinesque's description was based on the following description by 

 Bartram (9, p. 421): 



* * * Plumbs, &c . ; of the last mentioned genus, there is a native species grows in 

 this island, -n-hich produces its large oblong crimson fruit in prodigious abundance ; the 

 fruit, though of a most enticing appearance, is rather too tart, yet agreeable eating, at 

 sultiy noon, in this burning climate; it aft'ords a most dehcious and reviving marma- 

 lade, when preserved in sugar, and makes excellent tarts; the tree grows about twelve 

 feet high, the top spreading, the branches spiny and the leaves broad, nervous, ser- 

 rated, and terminating with a subulated point. 



This plum was observed on Pearl Island, La., probably between 

 August 5 and 27, and could therefore scarcely have been Prunus 

 angustifolia. In the fall of 1910 S. M. Tracy made a trip to Pearl 

 Island, but found no Prunus, and he has since learned from those 

 living in the vicinity that there have been no plum trees on the island 

 within the past 40 years. About 25 or 30 years ago, however, a 

 single wild tree, which has since died, was known on Isle au Pols on 

 the east bank of Pearl River. In Bartram's time these trees may have 

 been more abundant. 



Prunus declinata Marsh., 1785, Arb. Amer., p. 112, "Dwarf plumb." 



Marshall describes this as follows: 



This is of a small dwarfish growth, seldom rising above 4 feet high, but frequently 

 bearing fruit at the height of 2 or 3, which is small and almost black when ripe. 



Although sometimes cited as a synonym of Prunus maritima, the 

 fact that the beach plum was known to Marshall and that his descrip- 

 tion of P. declinata is quite as applicable to P. ■pumila renders the 

 usual disposition of Marshall's name somewhat doubtful. 



Prunus Jloribunda Hort., K. Koch, 1869, Dendrol., t. 1, p. 119. 



Cited as a garden name for P. 'pumila. 



X Prunv.3 horlulanarohv^ta Waugh, 1901, in Vt. Agr. Exp. Sta. Rpt. 14, 1900/01, 

 p. 277. 



This name was proposed by Waugh for a group of Prunus trifiora 

 hybrids which he designated the Gonzales group, and of which he 

 considered the variety Gonzales the type. To this group he referred 

 30 varieties, hy})rids (so far as the parentage is known) of P. trijlora 

 with P. amjvMifolia, P. anr/ustifolia varians, P. munsoniana, and 

 P. hortulana. Waugh's application of the name Tiortulana was not 

 in its original usage, but to ilie Wild Goose group, P. munsoniana, 

 while the variety Gonzales, although its parentage is not definitely
