ï~~ 24 THE MICHIGAN BOTANIST Vol. 50 ED VOSS-FIELD BOTANIST IN SUMMER, CURATOR IN WINTER A. A. Reznicek University of Michigan Herbarium 3600 Varsity Drive Ann Arbor, MI 48108-2228, USA No, I'm not suggesting that Ed led a dual botanical life. He was devoted to the vascular (especially the flowering) plants of Michigan at all seasons and throughout his life. But his botanical seasons were definitely compartmentalized, like so many other elements of his life. In summers (from mid-May to the Labor Day weekend, slightly longer after retirement) Ed was based "up north," staying at the Biological Station on Douglas Lake while teaching (for 36 summers; 1963-1974, 1976-1998, 2003; plus four years as a teaching assistant, 1949, 1951-1953) (Fig. 7). Ed attended the International Botanical Congress in Leningrad in 1975, John Thieret substituting for him that summer. When not at the station, Ed stayed at his cottage on the straits near the tip of the Lower Peninsula looking out over the Mackinac Bridge. He likely went in the field more often than any other botanist in the region. I always wished I could have as much field time as Ed. His field work, though, was usually tightly focused and organized, like everything else in his life. When he was teaching, he was scouting class trips and looking for new areas to take people or show them special things, such as transient species of disturbed habitats, which were always a challenge. However, he was always keen to explore a new bog or fen, and was especially interested in comprehensively documenting the plants of favorite areas in the straits region, including Grass Bay, the Headlands, or Saint Helena Island (Voss 2001). He built a great body of knowledge about plants of the Biological Station area, and his work, added to earlier collectors, made the Douglas Lake region (Emmet and Cheboygan counties) one of the best known in the state. In fact, this flora, including all the interesting Great Lakes endemics centered on the straits region, was the subject of his doctoral thesis (Voss 1954) and most of his botanical publications prior to 1957. The Douglas Lake region was so well known that it was a banner day when a new native species was added. So I was particularly lucky on 9 August 1978, the very first time I went out with Ed in the region, to spot right in the trail to Mud Lake Bog, Torreyochloa (Puccinellia) fernaldii-a new, though inconspicuous, native grass to the Douglas Lake area (which ended up as Voss No. 15,000). I felt then that I had passed muster as a field companion. Ed also collected in southern Michigan in the fall, often in conjunction with scouting for the well-known aquatic plants course which he taught for many years in Ann Arbor. He was especially fond of the Lake Erie marshes, and was interested in their dynamic changes with fluctuating lake levels. Whenever I was with him, he always enjoyed seeing if this was a year that the very local Bolto
