NATIVE AMERICAN SPECIES OF PRUNUS. Td 
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. 
Rafinesque’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, which 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 
sultry noon, in this burning climate; it affords a most delicious 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 Pois on 
the east bank of Pearl River. In Becta 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. pwmila renders the 
usual disposition of Marshall’s name somewhat doubtful. 
Prunus floribunda Hort., K. Koch, 1869, Dendrol., t. 1, p. 119. 
Cited as a garden name for P. pumila. 
X Prunus hortulana robusta Waugh, 1901, in Vt. Agr. Exp. Sta. Rpt. 14; 1900/01, 
p. 277. 
This name was proposed by Waugh for a group of Prunus triflora 
; hybrids which he designated the Gonzales group, and of which he 
q 
considered the variety Gonzales the type. To this group he referred 
30 varieties, hybrids (so far as the parentage is known) of P. triflora 
with P. ola’ P. angustifolia varians, P. munsoniana, and 
_ P. hortulana. Waugh’s application of the name hortulana was not 
in its original usage, but to the Wild Goose group, P. munsoniana, 
while the variety Gonzales, although its parentage is not defiely
