About 40% of the vegetation is evergreen, a somewhat higher 
figure than in the case of the red oak woods, but much lower than 
that of the otherwise similar sandy hammocks. This difference is 
unquestionably correlated with the richness of the soil. The abun¬ 
dance of vines is a good indication of the rarity of fire. Only one 
representative of the Ericaceae ( Batodendron ) is listed, and no 
Leguminosae. The scarcity of the former is probably correlated 
with the lime or potash in the soil, and of the latter with the abun¬ 
dance of humus. Most of the ferns grow on calcareous rocks in 
sinks or around mouths of caves, and it is not yet certain whether 
lime or shade or protection from fire is the most important factor 
for them. 
The high hammock soil is excellent for both general farming and
