After returning from their trip, they continued their botanical endeavors. The Lemmons co-developed the Lemmon Herbarium at their home at No. 5985 Telegraph Avenue,[14] later donating it to UC Berkeley, where it was later merged into and called the University and Jepson Herbaria.[15] Lemmon continued her botanical illustrations, including as the official artist for the California State Board of Forestry (from 1888–1892)[3] and acquired a national reputation for her work.[4] In 1882, she discovered a new genus of plants called Plummera floribunda.
