A large percentage of the vegetation is made up of ever- 

 greens. The rarity of fire is shown by the abundance of vines 

 and underbrush. 



High hammock soil is a very desirable one for trucking and 

 general farming, but is very expensive to clear for cultivation. 



LOW HAMMOCK. 



Low hammocks are nearly always a little lower than the 

 surrounding country, and damp, but hardly wet enough to 

 be called swamps. In low spots in these hammocks the vegeta- 

 tion is often essentially the same as that of the swamps. 



The trees are for the most part tall and straight, making 

 a dense shade. Fires rarely ever occur as the humus probably 

 never gets dry enough to burn. 



The following is a list of the principal plants observed. 



TREES. • 



Acer rubritm Red maple. 



Quercus nigra Water oak. 



Liquidambar styraciflua Sweet gum. 



Magnolia grandiflora Magnolia. 



Taxodium distichum Cypress. 



Quercus virginiana Live oak. 



Persea pubescens Swamp red bay. 



Fraxinus caroliniana Ash. 



Ilex opaca Holly. 



Carpinus caroliniana Ironwood. 



Quercus michauxii Swamp Chestnut oak. 



Nyssa biflora Black gum. 



Morus rubra Mulberry. 



Magnolia glauca Sweet Bay. 



Hicoria sp Hickory. 



VINES. 



Smilax lanceolata Wild smilax. 



Rhus radicans Poison Ivy. 



Vitis rotundifolia Bullace or Muscadine. 



Vitis aestivalis Wild grape. 



Bignonia crucigera Cross- vine. 



SHRUBS AND HERBS. 



Ilex vomitoria Yaupon. 



Serenoa serrulata Saw-palmetto. 



Aralia spinosa Prickly ash. 



Tillandsia usneoides Spanish moss. 



Violets, ferns and sedges. 



The percentage of evergreens is very nearly the same as in 

 the high hammocks. Vines and underbrush are also abundant.
