It will be noticed that the five pines, also Taxodium distichum, 
Nyssa uniflora, Phoradendron, Baccharis, and Tillandsia, occupy 
the same relative rank, or nearly so, in both lists. Acer rubrum 
and Liguidambar just about interchange places, doubtless because 
in March the former was in fruit, and therefore conspicuous and 
unmistakable, while the latter is not so readily identified when its 
characteristic leaves are off, especially in young trees which bear 
no fruit. Magnolia glauca, M. grandiflora, and Myrica certfera, 
which stand higher in the March list, are evergreen, and Quercus 
nigra nearly so in that latitude. 
From Walthourville to Jesup, Folkston, and Jacksonville, a 
distance of about 118 miles, my route was through flat pine barrens, 
averaging perhaps 50 feet above sea level, dotted with numerous 
very shallow depressions with no outlets, and traversed by sluggish 
streams, most of them mere branches, with their channels only a 
few inches or feet below the general level, and bordered by com- 
paratively wide swamps. This region corresponds approximately 
with Loughridge’s ‘ ue pine and palmetto flats’’* in Georgia, and
