Herbarium Gets New Plants

Professor Carl L. Wilson of the Department of Botany, during six weeks of his sabbatical leave spent at the Institute ofResearch in Central America on Barro Colorado Island in Gatun Lake, Canal Zone, collected a large number of plants which have been added to the Jesup Herbarium of Dartmouth College. Barro Colorado Island was set aside by the governor of the Canal Zone in 1923 as a reservation for the conservation and study of tropical plants and animals. Its four thousand acres are covered with luxuriant tropical rain forest, much of it primeval. A laboratory with comfortable living quarters is situated on the only clearing on the entire island. A network of twentyeight miles of trails covers the island. Of the plants collected by Professor Wilson, thirty-four had never been found on the island before; two were new to the Canal Zone; one was new to Central America; and one specimen was new to science.
