Women botanists -- Oregon -- Correspondence

Lilla Irvin Leach (1886-1980) was a field botanist who specialized in Oregon flora from 1915-1945. She discovered more than a dozen species and two new genera, Kalmiopsis leachiana and Bensoniella oregana. Lilla and her husband John Leach purchased a tract of land in southeast Portland where they developed a botanical garden named Sleepy Hollow. The collection includes correspondence, notes, notebooks, articles, and a few photographs.
