Early spring Erythronium hendersonii seen on Upper Table Rock, near Medford, Jackson County, Oregon

henderson'ii: after Louis Fourniquet Henderson (1853-1942), whom the Native Plant Society of Oregon has dubbed the "Grand Old Man of Northwest Botany." Henderson lived through the Civil War in Mississippi. His lawyer father was murdered in New Orleans during the Reconstruction period. He studied botany at Cornell and travelled west in 1874, moving to Portland three years later to take a teaching position. It was then that he began his serious botanizing in Washington and Oregon. He was Professor of Botany at the University of Idaho from 1893 to 1908. Sometime during this period his herbarium was destroyed by a fire, resulting in the loss of some 85,000 specimens. He became Curator of the Herbarium of the University of Oregon sometime around 1924, a position which he held for 15 years (ref. Astragalus accidens var. hendersonii, Dodecatheon hendersonii)
