22 HARPER: EXPLORATIONS IN THE COASTAL PLAIN 
terial, as far as it goes, seems to be a perfect match for the type- | 
specimen in the Torrey Herbarium, collected by Dr. Chapman in 
West Florida. 
QUERCUS MYRTIFOLIA Willd. 
Abundant on the driest sand-hills of the Satilla River in Pierce 
County near Waycross, where with other shrubby plants (and no — 
herbs or trees) it forms almost impenetrable thickets six to ten feet — 
high and of unknown extent (70. 7466). This locality is about 60 ~ 
miles inland and 100 feet above sea-level. On August 1g I col- — 
lected the same oak in a thicket of similar aspect, but somewhat _ 
different composition, in the interior of Cumberland Island (vo. 
1540). This species strikes me as being much more closely re- 
lated to Q. nigra L. (Q. aquatica Walt.) than to Q. Virginiana, of 
which it was long considered a variety. 
POLYGONUM ARIFOLIUM L. 
In the swamp of the Satilla River in Camden County opposite — 
Woodbine, within the influence of tide, but in fresh water, August 
23 (uo. 1563). My specimens are all sterile. Previous records 
of the occurrence of this species as far south as the coast of — 
Georgia seem to be lacking. With it I found among other things 
Juncus Canadensis J. Gay, which was also a novelty in these E 
parts. 
MAGNOLIA MACROPHYLLA Michx. 
This tree is common in rich woods along Samochechobee : 
Creek all the way across Clay County (vo. 7793), but I have — 
never met with it elsewhere. 
SARRACENIA FLAVA X MINOR Harper, Bull. Torrey Club, 30: 
332. Je 1903 
Although described from a single specimen, this hybrid seems 
to be not particularly rare or evanescent. In July, 1902, I found © 
(and photographed) several specimens within a few feet of each — 
other in wet pine-barrens in Douglas, Coffee County (mo. 74 Ey, 
Here, as at the type-locality (about sixty miles distant) both parr : 
ents were growing in the immediate vicinity. The hybrid hae 
shown no tendency to flower yet.
