Dear Mary Sue and All, I've taken my time in responding to your posting for it is both an interesting and a difficult question to resolve. However, if I simply navigate through the key within http://pacificbulbsociety.org/pbswiki/index.php/… it is quite clear from the instructions that we should include orchids that possess a pseudobulb. Perhaps some people, accustomed to seeing orchids at Trader Joe's or, in Europe, in supermarkets are not familiar with the appearance of pseudobulbs. Here is what a Dendrobium speciosum (found in Queensland, primarily) looks like after it has finished blooming: http://flickr.com/photos/andrewrmw/… f6ac0391b3d83a8f9ec5 Those are the pseudobulbs starting to work on putting shoots and energy together for next year, January here in California. Flowering follows, from then until April, in most years. On this basis I would say that the PBS directions for what constutes a 'bulb' are valid and that an orchid such as this belongs within the discussions at this site. The more difficult question is not technical but, as I pointed out I my posting 24 hours ago, how will inclusion of orchids such as this affect the conversations at this website? I am quite ready to accept the terms defined by the PBS board for 'bulb' and I hope others will do so as well. If we move in this direction I think it should be a move that has the acceptance of a firm majority. Otherwise, the move could lead to division within us. Andrew San Diego
