FLORIDA GEOLOGICAL SURVEY—THIRD ANNUAL REPORT. 
are protected from waves by the smallness of the pond or cove, or by other 
aquatic vegetation. About a dozen species have been reported from Florida. 
U. subulata L. is common on sandy shores of small lakes (and probably 
also occurs in peat prairies), and U. cornuta L. in a deep open tyty bay 
near Carrabelle and on moist sandy slopes in the pine woods in the south 
eastern part of Jackson County. 
SCROPHULARIACEAE. Figwort Family. 
Gerardia linifolia L. 
Cypress ponds, peat prairies, saw-grass marshes, etc.; not common. Jackson, 
Leon, Lake, Osceola and DeSoto Counties. 
Delaware to Florida, in the coastal plain. 
Macranthera fuchsioides (Nutt.) Torr. 
In estuarine swamps near Milton, Santa Rosa Co.; sometimes over ten feet 
tall. Also in branch-swamps in Walton and Washington Counties. Rare. 
Southwest Georgia to Louisiana, in the coastal plain. 
Gratiola ramosa Walt. 
Edges of shallow ponds, peat prairies, etc. Wakulla, Osceola, and doubt¬ 
less many other counties. 
South Carolina to Florida, in the coastal plain. 
Monniera Caroliniana (Walt.) Kuntze 
In still water of various kinds, from the estuaries of Santa Rosa County and 
the cypress ponds of Jackson County to the large lakes of Leon and Lake Coun¬ 
ties, the marshes of Crescent Lake, and the south end of the Everglades, fin 
other states it seems to be chiefly confined to small ponds.) 
Maryland (?) to Louisiana, in the coastal plain. 
LABIATAE. Mint Family. 
Lycopus pubens Britton? 
In a cypress swamp near Leesburg. The same or another species grows in 
cypress ponds in the East Florida flatwoods, and in gum swamps near Talla¬ 
hassee. They are doubtless common enough in other parts of the state, but I 
have not been able to identify them because they bloom in the fall. 
VERBENACEAE. Verbena Family. 
Avicennia nitida Jacq. Black Mangrove. 
A common shrub in salt marshes as far north as Cedar Keys and New 
Smyrna at least. On the coasts of South Florida it becomes a considerable 
tree, and must contribute more or less to the peat of the mangrove swamps. 
Coast of Mississippi to the Bahamas and Brazil. (Not yet known in Middle 
and West Florida and Alabama, however.)
