320 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 doubtless 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 Counties, the marshes of Crescent Lake, and the south end of the Everglades. (In 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 Tallahassee. 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.)
