FLORIDA GEOLOGICAL SURVEY—THIRD ANNUAL REPORT. 
on the east one also occasionally sees small shallow ponds char¬ 
acterized by an abundance of mayhaw, Crataegus aestivalis, a small 
tree which does not seem to grow in cypress ponds at all. Both 
gum and mayhaw ponds seem to occur in more clayey regions 
than most cypress ponds. 
BAYS. 
(PLATE 23.2. FIG. 22) 
Closely related to the cypress ponds are the bays, which seem to 
differ chiefly, as far as environmental conditions are concerned, in 
being situated on deeper sand (cypress ponds generally have clay, 
sometimes rock, under them within a very few feet of the surface) 
and having less fluctuation of water-level. For some reason not 
fully understood, the soil and water seem to be more acid than in 
the cypress ponds, and the vegetation comprises more small trees 
and shrubs than large trees. 
Bays are especially characteristic of the Middle Florida flat- 
woods (e. g., San Pedro Bay), and they are also common in the 
West Florida coast region, and occasional elsewhere in the northern 
parts of the state. The following list of bay plants is compiled 
from notes taken in Franklin, Gadsden, Leon, Wakulla, Jefferson, 
Taylor, Lafayette, Alachua and Levy Counties.
