294 HARPER: BOTANICAL EXPLORATIONS IN GEORGIA 
heard of a few sawmills in operation among these mountains, but 
saw little evidence of their work. The flora of the dry southern 
slopes of the mountains is not unlike that of some of the dry 
pine-barrens 100 miles farther south, being characterized by such 
species as Andropogon furcatus, Paspalum bifidum, Cyperus retro- 
fractus, Yucca filamentosa, Agave Virginica, Quercus Catesbaet, 
Ceanothus Americanus, Crotalaria rotundifolia, Indigofera Caro- 
lintana, Cracca Virginiana, Stylosanthes biflora, Vaccinium arbo- 
reum, Asclepias verticillata, Vernonia angustifolia and Chrysopsis 
graminifolia. On the shaded northern slopes however many 
Alleghanian species are met with, such as Dryopterts Novebora- 
censis, Uvularia perfoliata, Polygonatum biflorum, Trillium stylosum, 
Quercus rubra, Castanea dentata, Magnolia Fraseri, Heuchera 
Americana, Robinia Pseudacacia and Antennaria solitaria. Along 
the banks of the river at the base of the mountains two species 
which are usually confined to the swamps of the coastal plain, 
Nyssa uniflora and Cyrilla racemifiora, are quite common at 650 
feet altitude, the latter sometimes growing on rocky cliffs with 
Kalmia latifolia. The former extends up the river to Pike County. 
Near Woodbury, at about 775 feet altitude, are some bogs 
with a flora much like that of similar places around Americus, 
containing such lowland species as Lycopodium pinnatum, Cyperus 
Haspan, Eleocharis tuberculosa, Rhynchospora axillaris, Juncus 
trigonocarpus, Polygala cruciata, Rhexia Virginica, Eryngium vir- 
gatum, Gratiola pilosa and others which will be mentioned later. 
On the 29th I went over into Pike County a few miles, and col- 
lected a few plants in a similar bog at about the same altitude, 
which contained besides some of the species just mentioned Sc/eria 
trichopoda, Rhexia ciliosa, Cynoctonum sessilifolium, Viburnum 
nudum, Eupatorium verbenaefolium and FE. rotundifolium. 
On the 30th I proceeded to Griffin, twenty-nine miles farther, 
noticing on the way that Pinus palustris extended up into Spalding 
County to within a few miles of Griffin. One species was col- 
lected in the woods near the Experiment Station that afternoon. 
The next day I went by way of McDonough up to Atlanta, 
where I rejoined my brother. On September 3, we were at Col- 
lege Park, making collections in that vicinity, in the southern edge 
of Fulton County and adjacent portions of Campbell (nos. 1275-
