Jacob Knecht and I put this database together a while back in hopes that it will be useful for concerned growers. Unfortunately, there is a vast number of geophytes out there without any virus information at all. http://pacificbulbsociety.org/pbswiki/index.php/… I searched through and found that only *Eucharis candida *was reported to have a virus (Eucharis mottle virus) transmitted through seeds. This may happen because the virus itself is specific on Eucharis, although I cannot say for sure. Nhu Berkeley, CA -- http://www.flickr.com/photos/xerantheum/
