TL;DR: The present study is a long-term series on the ecological life histories of C?ypripedirtm, including stuldies on hybridization, mycorrhizae, 'seed germination, response to competition, and fruit development.
Abstract: It is a common observation of field botanists that certain years are "good years" for the flowering of various native plant species. The total flower crop in years far exceeds that usually produced by the same species. Other species may have their optima at other times. This annual fluctuation in flower production is particularly noticeable in the native orchids of the temperate zones, and is especially apparent in members of the genus Cypripedium L., the temperate zone Ladyslippers. The present study was initiated in 1932 with the aim of describing the magnitude of the annual fluctuation in the various species found in diverse plant communities in Wisconsin. It is part of a long-term series on the ecological life histories of C?ypripedirtm, including stuldies on hybridization, mycorrhizae, 'seed germination, response to competition, and fruit development (Curtis 1932, 1939, 1943, 1946; Duncan and Curtis 1942). Acknowledgment is gratefully made to the late Prof. Aldo Leopold and to Dr. H. C. Greene, Dr. Grant Cottam, and my wife, Jane, for aid in making the field counts, and to the late Martin Gillen for generous provision of facilities during part of the study. Species used. The Cypripediums used in this investigation are listed in Table 1, with nomenclature following that of Fuller (1933). In Wisconsin,
