Vol. XXVI, pp. 39-52 March 22, 1913 PROCEEDINGS in-i ii i BIOLOGICAL SOCIETY OF WASHINGTON A LIST OF PLANTS COLLECTED ON ST. VINCENT ISLAND, FLORIDA. BY W. L. McATEE, rj. S. Biological Survey. St. Vincent Island, Florida. Lies about 8 miles southwest of Apalachicola. It is the westernmost of a scries of islands which bound St. George's Sound, and its western extremity, at Indian Pass, is scarcely a quarter of a mile from the mainland. The island contains about 1200 acres, and on all parts of it (except marsh) visited by the writer, the soil is practically pure sand. That part of the island nearest the mouth of the Apalachicola River, which is said to have the richest soil, and where a greater variety of mainland plants would be expected, was not explored. A number of large ponds on the island drain through a channel which was dammed many years ago. The dam was allowed to disintegrate, hut was renewed and has now been in place again for several years. The ponds therefore have at least twice changed from brackish to fresh water. The plants reported upon were collected during investigations of the food habits of wild ducks, under authority of the Biological Survey. The writer was most hospitably entertained by Dr. R. V. Pierce, owner of the island. Doctor Pierce main-tains the island as a game preserve, and is especially interested in improving the supply of food for ducks. A number of plants have therefore been introduced. St. Vincent Island was a favorite collecting ground of Dr. A. W. Chapman, and no one regrets more than the writer that the worthy doctor did not see fit to label his specimens 10— Pr.oc. Biol. Sue. Wash., Vol. XXVI, L913. 13'J)
