The Arnold Arboretum cultivates an incredible collection of conifers. More than half of all the species of Pinaceae can be viewed in a matter of hours. Few places in the world offer this opportunity to observe so many species of the Pine family in close proximity. In this Sunday, July 31 workshop, Garth Holman will present the evolutionary history and diversity of conifers as well as how to identify them. He will begin indoors by explaining worldwide conifer relationships with particular emphasis on Abies, Cedrus, Larix, Picea, Pinus, Pseudolarix, Pseudotsuga, and Tsuga, the genera of Pinaceae which are represented in the Arnold collections. He will then lead a walk through the conifer collection to examine similarities and differences. The class will meet in the Dana Greenhouse Classroom beginning at 12:30 pm. To register, log on to www.arboretum.harvard.edu. Fee $35 Arboretum member, $45 nonmember.
