January 20, Saturday, 6:30 pm
Program: The Weird Beauty of Liverworts. Botanist Dr. David Wagner gives a talk and slideshow, with a focus on photomicrographs that get up close and personal with the graceful forms of liverworts. Hiding among the mosses in our forests are plants with a mossy aspect but in a completely different division: liverworts. Those with a ribbon-like thallus are easy to notice. Thalloid liverworts have an amazing diversity of structures from simple to complex. Leafy liverworts are more easily overlooked because they share the same life form and life cycle as mosses. Location: the Amazon Community Center at 2700 Hilyard St in Eugene. For more information call 541-344-3327.
January 21, Sunday, 10 am–1 pm
