Shipped with 15 pages of additions and corrections, these dated 26 April 2002. For nearly five years, this has been a kind of ghost title to me. I knew it was out there, but it was just too darned much trouble to get my hands on it. For the longest time, it wasn't known at, where just about everybody begins; it is listed there now, but "out of stock." So now its easily obtainable; I asked for an autographed copy, and darned if the two authors didn't sign the title page! That's no more than standard good manners from folks in Maine, but still.... The book is based on the herbarium holdings at the University of Maine, Orono, and the herbaria of the University of New Hampshire and Harvard University. The authors don't make a big to-do about it, but it is clear they insist on proper vouchers, and they exclude unvouchered materials from their coverage. They make the point on p. 8 that reports of Actinidia arguta and Aristolochia macrophylla are unvouchered, but then on page 10 it says these two (and many others) have been added to Maine's flora based on the existence of a voucher specimen. Well, we cannot have it both ways, but it is not terribly important, given that the two species are only local escapes from cultivation. The sequence of families is roughly Cronquistian; the genera within each family are simply alphabetical. The keys are conventional and quite artificial. The species descriptions are very brief, but longer ones can be had in any of a dozen other books that cover New England. The status of each species in Maine is emphasized, with extralimital ranges also given, and they give common names. As an Appendix II, the authors put in a key to genera for use with vegetative, non-emergent, aquatic plant material. That could turn out to be most useful, and far outside Maine, too. There are no illustrations, save for a cover illustration of a sprig of willow, Salix arctophila, rendered by the first author, Arthur Haines. This is explained on [unnumbered] page 2. But the cover illustration is initialed, m.m., in usual artist's fashion. The credit for the illustration can be left as one of the great unsolved mysteries in Maine botanical history, which is otherwise covered succinctly on p. 7. What the book needs is an outline map that shows all the counties of Maine. That would have been really nice on Cover 2 or Cover 3, or even in both places. A work like this merits a happy future, and maybe in the next printing they could sneak in an outline map. -Neil A.
