NATIONAL ACADEMY OF SCIENCES Colloquium Series
In 1991, the National Academy of Sciences inaugurated a series of scientific colloquia, five or six of which are scheduled each year under the guidance of the NAS Council's Committee on Scientific Programs. Each colloquium addresses a scientific topic of broad and topical interest, cutting across two or more of the traditional disciplines. Typically two days long, colloquia are international in scope and bring together leading scientists in the field. Papers from colloquia are published in the Proceedings of the National Academy of Sciences (PNAS).

National Academy of Sciences Colloquia Bound Reprints Available
In 1991, the National Academy of Sciences (NAS) inaugurated a series of scientific colloquia, several of which are held each year under the auspices of the NAS Council Committee on Scientific Programs. These colloquia address scientific topics of broad and topical interest that cut across two or more traditional disciplines. Typically two days long, these colloquia are international in scope and bring together leading scientists in the field.
Papers presented at these colloquia are published in the Proceedings of the National Academy of Sciences (PNAS) and are available online (www.pnas.org). Because they have generated much interest, these papers are now available in the form of collected bound reprints, which may be ordered through the National Academy Press.

COLLOQUIUM
Papers from the National Academy of Sciences Colloquium on Variation and evolution in plants and microorganisms: Toward a new synthesis 50 years after Stebbins
Ledyard Stebbins, the most eminent plant evolutionist of the twentieth century, died on January 19, 2000, just 8 days before the colloquium on “Variation and Evolution in Plants and Microorganisms” was held on January 27–29, 2000, at the Beckman Center in Irvine, California. The colloquium, which he planned to attend, was sponsored by the National Academies of Sciences to commemorate the 50th anniversary of the publication of Stebbins' classic book “Variation and Evolution in Plants.” These proceedings include the papers presented at the colloquium.
