Lodge Thompson County Park 360 Butler Ave. E., West St. Paul, MN 55118 by Anita F. Cholewa, Ph.D., curator of the UM Herbarium, Bell Museum Programs of Natural History, University of Minnesota. In last month’s newsletter, we learned a little about what scientific names The Minnesota Native Plant mean and how to pronounce them. Now, why do “they” keep changing the Society meets the first Thursday names? in October, November, December, To answer this, we must first consider what makes a species a species. February, March, April, May, and This sounds like a simple question, but it’s not — the answer has changed June. Check at over the centuries as we have gained a better understanding of nature. for more program information. Initially, a species was defined as populations that looked identical. 6 p.m. — Social period Eventually, a breeding requirement was included, and the definition changed 7 – 9 p.m. — Program, Society to populations that contained similar looking individuals with the potential business to interbreed and produce viable offspring. Then it was recognized that, at Feb. 4: “Looking at Lichens,” least in the plant world, external morphology could change depending on theby Dr. Imke Schmitt, assistant environment (desert plants can become more hairy during droughts; flowerprofessor, University of Minnesota. color could change due to soil pH; habit could change due to elevation;Plant of the Month: One-flowered etc.). Then it was discovered that plants, unlike most animals, can survivebroom rape or cancer-root, chromosomal alterations such as extra doubling or loss of a chromosome,Orobanche uniflora, by Ken Arndt, and many species were found to self-breed, and some species (for example,Critical Connections Ecological dandelions) don’t even need pollen to produce viable seed (known asServices, Inc. agamospermy).
