Frank Lang, professor emeritus of biology at Southern Oregon University, will present the first lecture of the Windows in Time lecture series for 2010, sponsored by the Southern Oregon Historical Society and the Jackson County Library System.

Lang will present "Ivan Elmore Applegate: The Erythronium Man" at noon Wednesday, Jan. 6, at the Medford library, 205 S. Central Ave., and at noon Wednesday, Jan. 13, at the Ashland library, 410 Siskiyou Blvd.

Applegate took up botany when he was a boy growing up on a farm in Klamath County. He evolved from an amateur to a professional botanist. His biggest interest was Erythronium, the lamb's tongue genus of the lily family.

His interest in the wildflower dates back to 1935, when the first lamb's tongue that he learned — a Southern Oregon/Northern California native — was unnamed. Applegate named the species Erythronium hendersonii S. Wats., for his friend Louis Henderson. He later named eight more taxa of Erythronium, and four other genera were named for him.

Lang taught systematic botany, plant ecology and biological illustration for 32 years at SOU. His research includes the history of botanical exploration in the Pacific Northwest, rare plant conservation, ferns and conservation issues. He is author of "A Nature Notes Sampler," which is a compilation of scripts from his Jefferson Public Radio program of the same name.

The "Windows in Time" lecture series will be held on the first and second Wednesdays of every month through 2010. Upcoming topics will include "Trees: An Arboreal Tour of Oregon" by Nancy Appling in February; "Tarnished Treasure: The Little Known Story of the Pokegama Plateau" by Connie Battaile in March; and "Jackson County Architecture: What Style is This Building" by Rod Reid in April.

The lectures are free. For information, call 774-8689 to reach the Medford library or 899-8123 to reach SOHS.
