therefore of considerable interest to ascertain what species 

 regarded as rather typical of the pine-barrens occur more 

 or less isolated near the fall-line. For some reason not altogether 

 obvious, the plants growing on uplands and along the larger 

 streams in the region under consideration are mostly of widely 

 distributed species, and the rarities are to be looked for in bogs. 



In Maryland, where the soil is mostly clayey, the bogs are 

 small and scarce and hard to find; and they are mostly of a 

 peculiar type described by Mc A tee a few years ago*, characterized 

 by very large quartz pebbles on hillsides. In the fall-line 

 sand-hills of the Carolinas and Georgia sandy bogs with quite 

 a number of interesting plants (such as Chamaecyparis and 

 Sarracenia flava) are not infrequent, but they become scarcer 

 again in Alabama, where the soil is more clayey. 



In the greater part of the central long-leaf pine belt of Ala- 

 bama the smaller streams dry up in summer, probably because 

 the hottest months are drier than they are farther east. But 

 in Chilton and Autauga Counties, between Maplesville and 

 Prattville, and particularly between Adams and Billingsley, 

 there are quite a number of pine-barren bogs where the water 

 seeps out perpetually on gravelly slopes. Those which I have 

 examined are close to the Mobile & Ohio (formerly Montgomery, 

 Tuscaloosa & Memphis) R.R., which was built in the last decade 

 of the 19th century. Although Dr. Charles Mohr may have 

 traveled on this railroad toward the close of his life, there is 

 little or no evidence of the fact in his Plant Life of Alabama 

 (1901), and the railroad is not shown on the map which forms 

 the frontispiece of that great work. 



I walked past a few of these bogs in the northwestern part of 

 Autauga County on Dec. 10, 1905, and examined quite a number 

 of them in Chilton County on April 28, 192 1, my attention 

 having been attracted by a pitcher-plant seen from the train 

 two days before. The same thing when seen in Autauga County 

 in the winter I had referred with some hesitation to Sarracenia 

 Sledgei, the westernmost species of the genus, f but when in
