Botanical studies at the northern tip of the Lower Peninsula of Michigan began long before the establishment of the University of Michigan Biological Station on Douglas Lake in 1909. However, since 1909 special efforts have been made to keep records of the local flora, and the "Douglas Lake Region" came to be defined as Emmet and Cheboygan counties, which share the tip of the Lower Peninsula and which provide precise, even if arbitrary, boundaries for the area under consideration. Some 20 years ago (1956) I presented a history of floristics in the region, including an account of published records which could not be accepted because of failure to find any correctly identified voucher specimens. A companion paper listing additional species known in the regional flora was prepared at the same time (published 1957). These papers supplemented the basic Gates and Ehlers list for the Douglas Lake Region (1925; additions 1928, 1931, 1948) and took into account published literature and herbarium specimens not necessarily related to work done in association with the Biological Station. The time seems ripe for a new supplement, while admitting that such a patchwork approach to an old list is less satisfactory than a complete new one, which time does not yet permit preparing. During the two decades since the previous list of additions, staff and students at the Biological station have continued to add to our knowledge of the local flora; and the first part, treating gymnosperms and monocots, of my Michigan Flora has appeared (1972). Preparation of the Flora meant intensive taxonomic investigations and herbarium studies, with resulting reidentifications and realignments for certain taxa.
