Use the online key to ferns and relatives at UW-Green Bay to key this fern to species. These fronds (feature “a”) are about 3 feet long. Sporangia (feature “b”) are located in the darker tan areas. species 2. Using resources you have learned about in lecture and laboratory, find 2 synonyms of the following species – Aster modestus Lindl. – sticky aster.

Using the Wisconsin State Herbarium Wisflora (http://www.botany.wisc.edu/cgi-bin/GenusList.cgi) and USDA Plants Database (http://plants.usda.gov/java/) websites, examine the distribution maps of the listed species below for more detailed distributions, give a common name for each, and answer the following questions: common name a.
