An old but useful book is Tuberous Cormous Bulbs by John Pate and Kingsley Dixon; publisher:///UWA/ Publishing, 1982 It covers Western Australian species but most of the information can be generalised to species from other parts of the world.

I'm interested in the story telling aspect of it, and Martyn Rix' "Growing Bulbs" has a great introductory chapter on the evolution of flowers that covers things like the Crocus, and subterranean ovaries as an adaptation to grazing pressure. Or for instance, fall blooming speciation as an adaptation to seasonal migration of grazing herds across elevational gradients. Beyond that book does anyone have any other books, articles, ideas, theories, etc? That might be useful in introducing evolution of geophytes as a curriculum? I'm leaning towards tying it in to current issues like zeric adaptations for changing climate or pollution tolerance, that sort of thing. Any help from this brain trust would be much appreciated!

Message-ID: <ba1fe838-b17a-fa43-0cf6-a8bc2b50fe97@earthlink.net> Content-Type: text/plain; charset=utf-8; format=flowed The ways in which bulbs multiply often seem to be adaptations to environmental conditions. For instance, the production of numerous tiny, loosely attached offsets (such as "rice grains" in some Fritillaria) is often associated with predation by digging animals such as bears and humans (e.g., consumers of Fritillaria camtschatcensis, Brodiaea californica, Camassia). The interesting bulb of Lilium pardalinum, which is elongated with very numerous scales, may reflect its typical habitat near mountain streams, where the bulb might be dislodged and distributed in spring. In both cases, the forms that bore many viable bulblets or scales would tend over time to dominate the population. Mark mentions Crocus and its subterranean ovary. You can tell when crocuses are ready to have their seed harvested because the capsule rather suddenly rises above soil level on a stem, so that the seeds will scatter. In nature one usually sees crocuses growing as scattered individuals, not the tight clonal clusters found in cultivation -- perhaps a respnse to burrowing predators.

I know for example that Irises are abundant in the extensive steppes of Siberia. This is a major location for the evolution of large herbivores. Tulips are also found here along with other bulbous plants. I know that Irises are loaded with alkaloids and poisonous to gracing animals. But, I do not know about the toxicity of Tulips and other bulbous plants found there. This is one of several mechanisms that plants have developed to successfully compete and survive.

I looked up walipini. The entry mentioned that the term refers to an earth-sheltered cold frame. It derives its name from the Aymaran languages. My brother did his doctoral research in the Peruvian Andes lo these many years ago. He learned both Quechua and Aymara languages. So of course I asked him about this. His reply: "Wali- is an Aymara root that means 'good.' Waliskiw means, things are good. Not sure about the -pini suffix. The cab driver that my brother and his wife had back from JFK was a Bolivian, grew up with Quechua-speaking parents, still knows it. He said he'd never had a Quechua-speaking customer before in his 35 years of driving. " Where were they coming back from? He had been at a conference in Durban. His wife came along. After the conference they took a long week in Cape Town, went to Kirstenbosh, up Table Mountain, etc. Most of the pictures he sent to me (taken with his iPhone) are not of interest to me and you. Here are three that make the cut. I'm pretty sure about the scadoxus. And is watsonia correct? Judy in NJ where the living history farm is scheduled to start tapping sugar maples this Saturday.
