HEINIG AND KALEB P. JANSSON CONNECTICUT ARBORETUM CONNECTICUT COLLEGE BULLETIN No. 6 NEW LONDON, CONNECTICUT DECEMBER, 1950 CHECK LIST OF WOODY PLANTS GROWING IN THE CONNECTICUT ARBORETUM AND GUIDE TO THE ARBORETUM RICHARD H. GOODWIN, (CATHERINE H. HEINIG AND KALEB P. JANSSON CONNECTICUT ARBORETUM CONNECTICUT COLLEGE BULLETIN No. 6 NEW LONDON, CONNECTICUT DECEMBER, 1950 INTRODUCTION One of the chief objectives of the Connecticut Arboretum has been to assemble a collection of all the species of woody plants native to the northeastern United States which can be grown in the New London area. This check list represents a report of progress toward this objective. It is hoped that it will serve the visitor and student of the local flora as a guide to the Arboretum and its collections. The map on page 16 shows the main Arboretum Tract and its various extensions and the Caroline Black Botanical Garden in relation to the Connecticut College campus. The more detailed map of the main Arboretum Tract on page 32 shows the layout of the paths and trails. The planted areas have been numbered to assist in the location of specimens. In this check list will be found all woody species known to occur naturally within the Arboretum, including adventives es- tablished at the time of the founding of the Arboretum in 1931 and native species which have been introduced into the area. The locations in the main Arboretum Tract where each species may be found are indicated by numbers referring to specific areas on the map (page 32). The distributions of some of the commoner species native to the woodland are not given. No attempt has been made to list the large number of ornamental trees and shrubs growing on the College campus and .n the Caroline Black Botanic Garden, but native and ornamental species in certain genera have been included, and their locations noted. The few exotic species which are found in the Arboretum are listed and their natural range is given. The plants in the check list have been grouped by families and genera according to the arrangement followed in the eighth edition of Gray's Manual.1 Species arc arranged alphabetically within the GINKGOACEAE genus. The taxonomic treatment is that of Gray's Manual, with the Ginkgo biloba L. GINKGO OR MAIDENHAIR TREE. 42a.

In cases where Taxus canadensis Marsh.
