HARPER: PINE-BARREN VEGETATION OF MissIssiIpPI 565 
near the coast. Pinus Taeda, on the other hand, is common in 
the Pearl River bottoms, and rare coastward. 
Pinus glabra Walt. is rather common near the Pearl and Leaf 
Rivers, and rare elsewhere in the pine-barren region. The same 
might be said of Taxodium distichum.

Fic. 3. Edge of cypress pond about a mile north of Fontainebleau, showing 
Taxodium imbricarium and Pinus Elliottii. July 17, 1913. 
Taxodium imbricarium (Nutt.) Harper (T. ascendens Brong.). 
On the 1913 trip first seen about 15 miles north of Gulfport, and 
last near Merrill, George County,* about 50 miles inland. (On 
the Mobile & Ohio R.R. it does not seem to reach the point where 
the railroad crosses the Alabama-Mississippi line.) In the Caro- 
linas and Georgia it extends about as far inland as 7. distichum 
does, but the inland limits of the two species are far apart in 
Alabama and still more so in Mississippi and Louisiana. 
Chamaecyparis thyoides (L.) BSP. Rather common in estu- 
arine swamps of the Escatawpa River (not the Pascagoula, which 
is muddy) near Moss Point, and seen also in a branch-swamp 
near the middle of Jackson County. 
Campulosus aromaticus (Walt.) Trin. Seen first in Forrest 
County, last in Jones County. Usually in damp pine-barrens with 
Rhexia Alifanus, as in the Carolinas. 
Hi This county was created from parts je Greene and Jackson Count! es in IgIo.
