The Friends of Wellesley College Botanic Garden, the Arnold Arboretum of Harvard University, and the New England Wild Flower Society will co-sponsor Mary Vaux Walcott: The Audubon of Botany, on Wednesday, July 13 beginning at 7 pm in the Arnold Arboretum’s Hunnewell building, 125 Arborway in Boston.  Mary Morris Vaux Walcott (1860 – 1940) was a gifted artist whose stunning watercolors comprise a catalog of North American wildflowers.  This talk by biographer Marjorie Jones reveals rich intersections of history, religion, politics, women’s studies, science, and art during the transformative times in which Walcott lived.  View the “Woody Plants” exhibition by the New England Society of Botanical Artists, on display July 8 – September 11 in the Hunnewell Building lecture hall.  Members of sponsoring organizations – free; nonmembers $5.
