Lemmon (January 2, 1832, Lima Township, Michigan – November 24, 1908, Oakland, California) was an American botanist and Civil War veteran and former prisoner of Andersonville.
He was married to fellow botanist, Sara Plummer Lemmon, and the two jointly cataloged numerous western and desert plants.
[1] Lemmon began corresponding with Henry Bolander at the California Academy of Sciences and Asa Gray at Harvard University, as he identified more hitherto uncatalogued plants.
While visiting Santa Barbara on a collecting and lecture expedition, Lemmon met Sara Plummer, a transplanted East Coast artist and intellectual who had developed an interest in botany.
[citation needed] On their return, they continued their botanical activities, ultimately establishing the Lemmon Herbarium, now part of UC Berkeley's University and Jepson Herbaria.
