Supported by a Sinnott Award, Callin Switzer with colleagues Robin Hopkins and Stacy Combes examined the unique method of pollination in mountain laurel. With the anther filaments acting as catapults, the pollen reaches speeds of 8 miles per hour, making it one of the fastest moving plants in the world! Abstract»Harvard Gazette»
At the Arboretum and across the globe, volunteers are challenging the notion that science happens behind closed doors. Citizen scientists—individuals who contribute their time and efforts towards observation and data collection—are transforming the nature of scientific discovery through their collaborative efforts with professional researchers. Around the world, citizen scientists work alongside professionals in fields ranging […]
Peter Del Tredici, Senior Research Scientist Emeritus at the Arboretum, co-authored a study on the discovery of a new hemlock from Korea. The first novel conifer species to be described in a decade, the Ulleungdo hemlock interests biologists and horticulturists due to its natural resistance to the hemlock woolly adelgid.
With three to four times the botanical diversity of North America, China is a hotspot in our search for rare and unusual plants. Last September, the Arboretum joined a two-week expedition in Sichuan with the North America-China Plant Exploration Consortium (NACPEC). Harvard Magazine’s Jonathan Shaw shares the compelling story of the team’s journey, unforeseen challenges, […]
