356 FLORIDA GEOLOGICAL SURVEY--THIRD ANNUAL REPORT.
MU1SCI. Mosses.
Thuidium sp.
In non-alluvial swamps in Leon, Lake and DeSoto Counties. Also in damp woods of various other kinds.
Leucobryum glaucum (L.) Schimp.
In a gum swamp about five miles west-northwest of Tallahassee.
Sphagnum macrophyllum Bernh.
In shallow bays in Jefferson County, etc.
New Jersey to Alabama, in the coastal plain.
Sphagnum sps. Peat Mosses.
Several other species occur in various parts of Florida, mostly in nonalluvial swamps, slash-pine bogs, bays, and other wet 'shaded non-calcareous places. They are most common northward, and I have not noticed any farther south than DeSoto County.
H'EPATICAE. Liverworts. Pallavicinia Lyellii (Hook.)
On the ground and roots of trees in non-alluvial swamps in Leon, Lake, Polk and DeSoto Counties; not rare.
(Many other liverworts, as well as mosses, grow on trunks of trees in swamps of all kinds, but they contribute such an infinitesimal share to peat formation that they are hardly worth mentioning in a treatise of this kind.)
CHARACEAE.
Chara sp.
Entirely submerged in estuaries of the Blackwater River, Santa Rosa County. Something very similar grows in Ponce de Leon Spring, Holmes County, and doubtless in many other deep bodies of fresh water.
