Page  76 ï~~76 THE MICHIGAN BOTANIST Vol. 39 the change from unlobed through 6-lobed is a strong widening of the angle between the two sides of the lower one-third to one-half of the blade. It should be interesting to determine whether character states similar to those described here for southeastern Michigan occur as well in other parts of the wide range of sassafras. For their aid in studying these populations, I acknowledge with thanks William Brodowich, Robert Masta, and Steven Kobylarz. LITERATURE CITED Barnes, B. V. & W. H. Wagner. 1981. Michigan Trees.

Rudolph, just "Rudy" to the thousands whose lives he touched during his long tenure in Botany at the Ohio State University. It is richly illustrated with over 200 b/w and colored photographs. The color cover features hollyhocks, to honor Rudy's observation that their introduction from Europe serves "to remind us of man's attempt to preserve the familiarity of his surroundings."

Page  77 ï~~2000 THE MICHIGAN BOTANIST 77 The editors have gone through Rudy's files and archives and extracted thirty papers, presented here in eight parts: 1) Botany in Textbooks, 2) Botany in Children's Books, 3) Botanical Teaching in Classrooms and Laboratories, 4) Botanical Educators, 5) Botanical Illustration, 6) Women in the Development of American Botany, 7) Writing the Missouri Botanical Garden History, and 8) Writings on Selected Topics in American Botanical History. I know of no parallel to this book. Certainly, in literature and music there are ample precedents for publishing incomplete works posthumously, but scholarly work generally requires the hand of the author himself or herself to make it complete. Nonetheless, the editors undertook to bring these papers to light. Emanuel D. Rudolph (1927-1992) left us too soon, and his editors have filled in the lacuna. Given the nature of the material, the book cannot be read as a continuous narrative or disquisition. Necessarily, it jumps from one thing to another, even with the best efforts of the editors to fill in details and provide a context. I think readers will enjoy this: it is a sampling of the range of the man's mind and interests, and one can jump in at almost any point and benefit from Rudy's spare prose and (often) wry insights. The editors are to be congratulated for carefully labelling the original nature of each contribution-whether it was intended as a presentation at a scientific meeting, a paper someday to be submitted for publication, or whatever. The editor of Sida Miscellany, Barney Lipscomb, deserves special mention and thanks for having perceived the value of this sort of work, and he doubtless spent many an hour with the editors in seeing this unusual synthesis into print. It is typographically flawless, and the photographs are faithfully reproduced, liberally captioned, and always given proper attribution. Neil A.
