Bulbs and corms as food source...

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.)
