So should we now use their acronym 'USO' instead of 'geophyte'? [USO = Underground Storage Organs] BTW, I found a link to the article at <http://springerlink.com/content/288g93472x2000k2/…>. It gave a table of all the geophyte species they tested. I've appended the table below, in case you can't access the link, as tab-delimited text for those who want to see it. (And you can cut and paste it into a separate file and open it with Excel to re-produce it in table form if you want.) P. C.
