396 Harper: BoTraNnicAL EXPLORATIONS IN GEORGIA 
My specimens were collected on August 28 in an open bog 
near Woodbury, Meriwether County, at about 775 feet altitude 
(no. 1254). They were accompanied by an interesting association 
of plants, most of them coastal plain types, such as Lycopodium 
pinnatum (no. 1255), Eleocharis tuberculosa, Rhynchospora axil- 
laris, Juncus trigonocarpus (no. 1253), Polygala cruciata (no. 125 7h 
Eryngium virgatum (no, 1252) and Gratiola pilosa. This locality 
is about 25 miles from the nearest part of the coastal plain. 
Before this time apparently only two or three of our North 
American species of Xyris, namely, XY. flexuosa, X. montana and 
perhaps X. Caroliniana, had been known outside of the Atlantic 
coastal plain, and it is noteworthy that in these three species A. 
scabrifolia finds its nearest relatives, 
Dr. Engelmann, in Plantae Lindheimerianae,* described a 
variety scabra of X. Caroliniana, but his plant is now treated as 
identical with X. flexuosa, and his description shows that it ts 
quite different from my plant. 
In Dr. Mohr's herbarium (now deposited in the U. S. National 
Museum) there is a specimen which is doubtless my X. scabvifolia, 
mounted on the same sheet with two specimens of X. flexuosa 
collected near Mobile, July 14, 1883. 
JUNCUS MEGACEPHALUs M. A. Curtis 
Collected in low grounds just back of the sand-dunes on 
Tybee Island, June 21 (no. 925), where it was accompanied by 
J. aristulatus (no. 926) and several other plants mostly maritime ; 
also in a moist shaded sandy place among the lime-sinks east of 
Muckalee Creek in Lee County, August 2 (no, 1159), with 
Cyperus cylindrostachys, Dichromena colorata (no. 1157) and one 
or two other species which I had previously seen only along the 
coast. 
The differences between this long-neglected species and its 
relatives were well pointed out by Mr. Coville + several years ago, 
and my specimens agree perfectly with his description ; they have 
also been examined by him and compared with authentic speci- 
mens. I do not find that this species has been 
reported from
