16 HARPER: EXPLORATIONS IN THE COASTAL PLAIN 
(no. 1762), Sanguinaria Canadensis, Actaea alba, Xanthorrhiza — 
apiifolia, Hydrangea arborescens, Viola tripartita glaberrima, Dirca — 
palustris (no. 1790), Panax quinquefolium, Kalmia latifolia and — 
Phryma Leptostachya, associated with coastal plain types like Pinus 4 
glabra, Rhapidophyllum Hystrix and Magnolia grandiflora. Other — 
very interesting plants were found on the banks of the Chattahoo- 
chee River near Georgetown (in the Cretaceous region) and Fort — 
Gaines (Eocene). } 
On October 23, in company with Mr. Hyde, I visited a cave P 
(known as Grier’s Cave), in Randolph County, about ten miles ; 
north of Cuthbert. Over several acres around this cave a com- — 
pact limestone of the Midway or Clayton period (lowest Eocene) : 
crops out in huge boulders and ledges, and supports a deciduous : 
forest containing a great variety of herbs as well as trees. The | 
aspect of the place is much like that of the Mountain Limestone — 
area at the north end of Pigeon Mountain in Walker County,* 3 
and some species are common to the two places. An interesting 
feature of the flora of the rocky woods around Grier’s Cave is the 3 
large number of plants with barbed fruits, adapted for dissemina- 3 
tion by animals. Representatives of at least six families with this 
adaptation were observed. 
The following species of more than ordinary interest were col- _ 
lected or observed in 1902: ‘ 
: 
ADIANTUM PEDATUM L, 
Grows luxuriantly on the steep shady north side of a high bluff 
along Samochechobee Creek in Clay County, where I collected it 2 
on October 28 (xo. 1786). This locality (in latitude 31° 38’) © 
is, I believe, considerably farther south than any other known for 
this species, and is the only one known in the coastal plain im — 
Georgia and adjacent states. : 
ADIANTUM CAPILLUS-VENERIS L. a 
Very abundant on the perpendicular rocky walls (Eocene) of 
the same creek near its confluence with the Chattahoochee Rivet 
just above Fort Gaines. Seen also on the bluff of the river itself
