If you have a high speed internet connection and the QuickTime plug in for your browser, take a look at this link: http://sunflower.bio.indiana.edu/~rhangart/… It has informative text on 10 plants, mostly bulbous, and shows time-lapse sequences of them opening, explaining a bit about how they do it, and closing. The flowers include: Passiflora, Narcissus, Crocus, and Amorphophallus titanum. Just select each plant from the left column to see it in the right window. I don't know if the download time on the files would be prohibitive for a dial up connection. Mark Wilcox Washington, DC
