330 FLORIDA GEOLOGICAL SURVEY-TIIIRD ANNUAL REPORT.
RHAMNACEAE. Buckthorn Family.
Berchemia scandens (Hill) Trel. Rattan Vine.
Very characteristic of calcareous swamps, low hammocks, etc. Wakulla, Jefferson, Duval, Putnam, Levy, Sumter and Orange Counties. Not observed in the southern half of the state.
Virginia to Florida, Missouri and Texas, mostly in the coastal plain and Appalachian valley.
ACERACEAE. Maple Family.
Acer rubrum L. Red Maple.
Common in both calcareous and non-alluvial swamps, down to about latitude 260 (New River). Not usually on the best kind of peat. (In the adjoining states it seems to avoid limestone.) The variety tridens grows in the swamps of some of the medium-sized rivers which rise and fall a few feet but are rarely or never muddy, particularly the Suwannee.
Nearly throughout temperate Eastern North America.
AQUIFOLIACEAE. Holly Family.
Ilex Cassine L. Swamp Holly.
Nearly throughout the state, in swamps whose water-level varies but a few inches during the year. (This excludes it from alluvial swamps and salt marshes, but it seems to grow equally well in calcareous and non-calcareous swamps.) It often grows on several feet of peat, as for instance in the clumps of small trees in peat prairies.
Virginia to Louisiana in the coastal plain, usually not more than fifty miles inland.
Ilex myrtifolia Walt. Yaupon or Yupon.
Common in shallow bays and cypress ponds north of latitude 3o0, all the way across the State. Rarely if ever on peat deep enough to have any commercial value.
North Carolina to Louisiana, in the coastal plain.
Ilex coriacea (Pursh) Chapm.
In estuarine swamps near Milton, and in bays, etc., in Escambia, Walton, Holmes and Jefferson Counties.
Virginia to Louisiana, mostly in the coastal plain.
Ilex glabra (L.) Gray. Gallberry.
Common in low pine lands and about high-water mark on sandy shores of small lakes, in the northern half of the State. Also on peat in the estuarine swamps of Santa Rosa County, and in small peat prairie, in Franklin and LakeCounties ...,
Nova Scotia to Louisiana, mostly in the coastal plain .. .
