HOTANLCAL SURVEY OF DISMAL SWAMP REGION. 



The si mini pine woods. — Many of the species just enumerated 

 form the chief undergrowth of the dry, flat pine woods, which often 

 border the dune area on its inner side (ligs. 70, 71). They form the 

 transition to the forested plain beyond, but can be more conveniently 

 classed with the fixed dunes. The principal tree is loblolly pine 

 (Pinna faeda). Aruliu spinosn (1 to ■'> meters, •'> 1o 10 feet, high), 

 Xanthoxylum clava-herctilis (attaining a height of (! meters, 20 feet), 

 and CuIlieitrjHt itmericaiia are more eharaeteristie of this formation 

 than of any other in the region. Gelsemium sempervirens, Tecoma 

 radicitns, and other lianas are abundant, Teeoma in places ascending 

 the trunks of all the small pine trees, and giving to such areas a pecu- 

 liar and striking appearance. Where the strand forest is somewhat 



Strand pine woods at Ooeanview, Yn, 



moist, Baccharis halimifolia is often Ihe principal element of the 

 undergrowth. In very dry soil, in openings among the trees, sand 

 blackberry (Rubus cunrifolius), starved specimens of black locust 

 (Robinia pseudacacia), and Chiekasaw plum (Primus nngustifolia) 

 sometimes form small, low thickets. 



The herbaceous species that occur in this association are chiefly 

 such as characterize the drier parts of the inland forest generally. 

 Opuntia opuntia and Yun-n filamt ntosa, however, appear to be more 

 at home here than elsewhere. Compositae (specie's of Solidago, Kupa- 

 torium, Elephantopus, Krechtites, ami Chrysopsis), Leguminosae 

 (species of Meibomia (Desmodiuiu) and Lespedeza), Ikmthonia seri- 

 cea, Uniohi laxa (yracdis), and Conrol villus ainericanus are worthy
