biviitata is also taken abundantly sweeping the grassy 

 floor. In Florida, Hysteropterum punctiferum occurs very 

 abundantly on the sparse vegetation of the pine-barrens. 



THE LITTORAL OR SALT MARSH ASSOCIATION 



The strip bordering the Gulf of Mexico furnishes a 

 strand flora and fauna that is quite varied and distinct 

 from that of the remainder of our territory. On the inner 

 zone of the beach are found the sea-side morning glory, 

 and Uniola paniculata, commonly known as sea-oats. Upon

the higher sand ridges and dunes back from the beach are 

 found Pinus taeda and australis, Quercus geminata and 

 virginiana, Sabal minor, Serenoa serrulata, Ilex vomitoria, 

 and Myrica cerifera. 



Running back from the salt marshes are numerous 

 bayous. The shallow, tranquil waters of these bayous, or 

 inlets of the sea, with their floor of deep sandy mud are 

 covered almost exclusively by the black rush (Juncus roe- 

 merianus). Associated with the latter are Spartina patens, 

 Fimbristylus spadicia, F. castanea, Paspalum vaginatum, 

 Chaetochloa imberbis perennis, and Distichlis spicata.
