564 HarPER: PINE-BARREN VEGETATION OF MISSISSIPPI 
Fall-line sand-hills of South Carolina (March) 59 per cent.; 
(July) 37.5 per cent.* 
Pine-barrens of southern South Carolina (March) 72.4 per 
cent.; (July) 53.8 per cent.f 
Flat pine-barrens of southeastern Georgia and northeastern 
Florida (March) 66 per cent. 
Altamaha Grit region of Georgia (December) 56.9 per cent.§ 
Lime-sink region of Alabama (original forests) 75 per cent.; 
(present condition) 65 per cent.|| 
Southwestern pine hills of Alabama (original forests) 84 per 
cent.; (present condition) 72 per cent.§] 
All these figures, except those for Alabama, are based almost 
entirely on car-window notes, like those for Mississippi, and are 
doubtless too low, for such notes do not do justice to the abundance 
of the conifers. The winter figures for evergreens are higher 
than the corresponding summer ones, on account of the difficulty 
of recognizing some of the deciduous trees in winter. 
NOTEWORTHY SPECIES 
The following notes on distribution are based on the trip of 
1913, unless otherwise indicated. 
Pinus Elliottii Engelm. The northwesternmost stations I 
have observed for this species, in different years, are as follows: 
(1) Onthe Mobile & Ohio R.R. between Winchester and Waynes- 
boro, Wayne County; (2) on the New Orleans, Mobile & Chicago 
R.R. in the upper edge of Perry County; (3) on the Mississippi 
Central R.R. a little west of Hattiesburg; (4) on the Columbia 
branch of the Gulf & Ship Island R.R. in the lower edge of 
Lamar County a little west of Lumberton. These points may 
be taken as marking approximately the limits of its range in that 
direction.** Like most other typical pine-barren plants in Missis- 
sippi, it is not known west of the Pearl River, and is most abundant
