Juncus biFFusisstmus Buckley 
On July 3 I found a most luxuriant growth of this species 
(no. 995), ina marshy place near Stillmore, Emanuel County, thus 
extending its known range about 150 miles farther eastward than 
the station reported by me* last year. Associated with it were 
Panicum scabriusculum, Sagittaria Mohrii (no. 994), Eleocharis 
tuberculosa, Juncus Elliottit, J. polycephalus, J. trigonocarpus, Sar- 
racenta rubra, Rhus Vernix and other species of more or less inter- 
est, the Sagittaria being also considerably farther east than it had 
been reported before. ; 
IRIS VERNA L, 
This species, usually in the southeastern states an inhabitant 
of dry pine-barrens, was collected on August 29 on the northern 
slopes of the Pine Mountains in Meriwether County, at about 800 
feet altitude (no. 1266), and seen five days later and 200 feet 
higher in dry woods in Campbell County, but without traces of 
flower or fruit at either locality. 
As noted by Dr. Small + a few years ago, the leaves of this 
species become considerably elongated in summer, but he failed 
to mention the interesting fact that although equitant, they are 
decidedly dorsiventral, being bright green on one side and glau- 
cous on the other. They spread out like a fan and bend away 
from the rootstock (which is perpendicular to the plane of the 
leaves), in this way bringing the green side uppermost. 
GYMNADENIOPSIS NIVEA (Nutt.) Rydb. 
Habenaria nivea (Nutt.) Spreng. 
Collected in the pine-barrens of Bulloch County, June 15 and 
26 (nos. 892, 954). One of the specimens of the latter number 
was the largest I ever saw, being nearly 6 dm. tall, with about 
sixty flowers in the spike. The object of mentioning this species 
here, however, is to note that the flowers are plainly 5-ranked in 
the spike, as may be readily ascertained by looking at a living
