**Comments:** Treatment: *Metasequoia* was preserved in 50% glycerol and 50% deionized water by Linda Klise, Sept. 13 - Sept. 21, 2004. According to an unpublished article by A. B. Beaudoin, *On the development, care, and maintenance of reference and subfossil seed and plant macroremains collection*, "specimens that are soaked in a preservative cannot be used directly for SEM work, because chemicals used in the preservatives volatilize in the vacuum chamber and can damage the SEM equipment. Of the chemicals used as preservatives, glycerol and formalin are especially damaging for SEM equipment." (George Braybrook, pers. Comm.).
