336 Harper: BoTraNicAL EXPLORATIONS IN GEORGIA 
This is probably the same species found by Dr. Mohr on the 
mountains of Clay and Talladega Counties, Alabama, and referred 
by him to P. serotina neomontana Sudw., for his description * 
(written of course before P. Cuthbert was published) exactly fits 
my specimens from the corresponding portion of Georgia. 
KRAMERIA sECUNDIFLORA DC. (KX. lanceolata Tort.) 
Collected on the sand-hills of Big Lott’s Creek, Bulloch 
County, June 27 (no. 971), and seen the next day in similar situa- 
tions in Emanuel County, near the rosemary sand-hills. This 
species has not to my knowledge been reported from Georgia 
before, or from any adjacent state except Florida. In Bulloch 
County it is known as ‘“‘sand-spur,” a name which in Southwest 
Georgia seems to be applied exclusively to Cenchrus echinatus. But 
I found to my surprise that no species of Cenchrus seems to be 
known in the upper part of Bulloch County, and the farmers there 
are to be considered fortunate in not having made the acquaintance 
of these pests. 
BapTisiA PERFOLIATA (L.) R. Br. 
A common and conspicuous inhabitant of the dry piné-barrens 
of Bulloch and other counties in the eastern part of Georgia. Col- 
lected along the railroad at Butts, Emanuel County, June 6 (no- 
802). It has rather a restricted range, being known only from 
South Carolina and Georgia and probably not occurring west of 
the Ocmulgee River. The westernmost point at which I have 
seen it is in Montgomery County. 
This species has several peculiarities which have never been 
described, though they are doubtless well known to the few bota- 3 
nists who have collected it. Its most striking feature is that the 
perfoliate leaves on the almost horizontal widely spreading branches 
oi ~ placed vertically, exposing both surfaces equally to the su” 
and giving the plant a most striking appearance. The phyllotaxy 
is : : ; q 
even more peculiar, the leaves being arranged very nearly in@ 
single row on each branch, with the midribs all pointing toward 
the zenith. Strictly speaking, they alternate in two rows, with an 
angular divergence of 15 or 20 degrees between them, instead of 
180° as in most cases of two-ranked leaves. These peculiarities
