Calla palustris

Call it an occupational hazard but I began to wonder one day how many genera were unique, that is, they had just one edible species in them, the so called monotypic genus. Some families are huge such as the sunflower family which has 1550 genera and 24,000 species. The oxalis genus has some 800 members. Worldwide there are more than 16,000 genera and over one million different species, of which perhaps 135,000 are edible, a little more than 10 percent. There are some 438 monotypic genera, each with just one species in it. But, how many edibles are among them? I knew of five edible plants locally that were all the only species in their genus. So I began to collect them, with thanks to KoolAid_Free_Lexi. At the moment I am at 64, the largest collection of them in one place. I’m sure some my readers, like Kool AId,  will send me more monotypic genus edibles, all unique in their own way. In the list below there are a few well-known plants: Gingko, dill, fennel, Saguaro cactus, saw palmettos, hydrilla, brazil nuts. Others are rare if not obscure, endangered and some federally protected.
