But this is precisely what is happening with Galanthus alpinus var. bortkewitschianus! It does not reproduce sexually. Mark " Jim Waddick's question about what we should call the old stoloniferous clone of Tulipa clusiana opens another can of worms. The plant in question is a clone. Formal botanical nomenclature does not have a rank corresponding to clone (unless you accept Individuum as a formal rank). Ranks such as subspecies, varietas, forma are not suitable because they imply the existence of a sexually reproducing population." _______________________________________________ pbs mailing list pbs@lists.ibiblio.org http://pacificbulbsociety.org/list.php http://pacificbulbsociety.org/pbswiki/
