enough, and shallow cypress ponds, which get too dry in spring. Common in 
small lakes, permanent cypress ponds, the wetter parts of peat prairies, etc. 
Probably occurs in every county in the State. After the water-lilies this is one 
of the pioneers in the formation of good peat. 
Nearly throughout the glaciated region and coastal plain of temperate 
Eastern North America. Also reported from Central and South America. 
ERIO CAUL ACE AE. 
Eriocaulon decangulare L. White-heads. Buttons. 
In wet pine lands, sandy bogs, bays, estuarine swamps (with sour water), 
peat prairies, etc. Common in the northern half of the State. 
New Jersey to Texas, mostly in the coastal plain. 
Eriocaulon compressum Lam. 
In fresh marshes, peat prairies, cypress ponds, shores of small lakes, etc.; 
never in running water. Often on several feet of good peat. Rather common 
from DeSoto County northward. 
New Jersey to Texas, in the coastal plain. 
Syngonanthus flavidulus (Mtx.) Ruhl. 
Low pine lands or flatwoods, shores of small lakes, drier parts of peat prai¬

peat. Santa Rosa, Leon, Jefferson, and other northern counties.

Two or three other species which have not been identified (for they bloom 
mostly in late summer) grow in similar places, and on shores of small lakes. 
MAYACACEAE. 
Mayaca Aubleti Mx. (and perhaps M. fluviatilis Aubl., if that is a distinct 
species.) 
In estuarine swamps near Milton, and non-alluvial swamps near Arcadia. 
Also in wet pine lands in West Florida and around ponds near Tallahassee.
