( 7 STUDIES IN THE TAXONOMY AND DISTRIBUTION OF THE EASTERN NORTH AMERICAN SPECIES OF LOBELIA Rogers McVaugh (Plates 435 and 436) The present paper is intended as a study of the distribution of the species of Lobelia native to the eastern part of North America, with a view to establishing better understanding of the relationships within the group, the possible origin of the various species, and the relation of this group of species to the worid-wide genus Lobelia. Eariy in the study it became clear that the identities of various species were much in doubt, which necessitated considerable taxonomic work, in an effort to clarify the situation so that significant distributional studies could be made. Most of the work has been carried on at the Botanical Laboratory of the University of Pennsylvania during the years 1933-1935. Two summers have been spent in this time in eastern New York, largely in botanical studies, so that the writer has been able to gain acquaint- ance with all the northeastern species in the field. The remaining species have been studied only from herbarium material. During the course of the project about 7000 sheets of dried material have been examined. This has been made possible through the generosity of the following gentlemen, to whom the writer wishes to express his sincere thanks: Dr. R. M. Anderson, National Museum of Canada, Ottawa, Can.; Dr. W. C. Coker, University of North Carolina, Chapel Hill, N. C; Dr. E. L. Core, West Virginia University, Morgan town, W. Va.; Mr. C. C. Deam, Bluff ton, Ind.; Dr. J.
