596 HarpPER: DISTRIBUTION OF PLANTS OF THE COASTAL PLAIN 
men from Harper’s Ferry (which is not only among the mountains, 
but about 300 miles farther north than any living botanist has 
seen this characteristic pine-barren plant); but I have recently 
shown* that the mountain plant belongs to a different genus. 
Croom did not find O. filiformis in the vicinity of New Bern, 
Kearney does not mention it at all in his Dismal Swamp report, 
and all the specimens cited in Coulter & Rose’s latest monographt 
are from Florida and Mississippi. In 1906 I did not see it north 
of Williamsburg County, South Carolina. 
NyssA UNIFLORA Wang. 
Last seen in Virginia, in swamps of the Chickahominy River 
about 18 miles east of Richmond, between the stations of Provi- 
dence Forge and Elko, with Taxodium distichum as usual. I have 
found no record of any other station for it north of the James 
River. 
RHEXIA ALIFANUS Walt. (See Bull. Torrey Club 33: 238. 1906.) 
Common in moist pine-barrens; last seen in Washington 
County, North Carolina, about 13 miles south of Plymouth. 
Kearney puts its northern limit at lat. 35°, about 50 miles farther 
south. 
GorRDONIA LASIANTHUS L. 
First seen (after leaving Georgia) about ten miles W.N.W. of 
Wilmington, and last about five miles S.S.E. of Washington, in 
Beaufort County, North Carolina. Three years before, I identified 
it with certainty only in Duplin County, in the same state.t This 
handsome tree seems to have been credited to Virginia first by 
Pursh and later by nearly every subsequent monographer, but 
this is probably a mistake. Kearney places its northern limit 
at latitude 34°, and it does not seem to be mentioned in any of 
the other papers on the Dismal Swamp region cited in his report. 
CyRILLA RACEMIFLORA L. 
Seen only in North Carolina (as in 1906), first near Hamlet, 
and last about 9 miles south of Plymouth. My 1906 notes placed 
it within still smaller limits.§
