The term "bulbs" in this definition is inclusive. Lists can include geophytes, as well as plants with corms, rhizomes, tubers, tuberous roots, not just bulbs. We've discussed on this list a lot what exactly can be included as our subject and we've never come up with an exact definition. There always seem to be exceptions. Some plants we talk about aren't really geophytes since they are evergreen. We have chosen to allow flexibility about this. Mary Sue
