The Arnold Arboretum presents an exciting lecture series in 2011: the new Director’s Lecture Series at the Hunnewell Lecture Hall, 125 The Arborway in Boston. The lectures are free but advance registration is required.
On Monday, February 7, from 6:30 – 8:30 pm, botanist Robert Robichaux of the Hawaiian Silversword Foundation and University of Arizona discusses recent efforts to restore Hawaii’s Marvels of Evolution. Evolving in splendid isolation over millions of years, Hawaiiâ€™s native plants exhibit patterns of diversity that are unrivaled elsewhere on Earth. Especially striking are the many examples of adaptive radiation, in which original immigrants to the islands evolved into dazzling arrays of plants exhibiting great variation in form and habitat preference. Yet, Hawaiiâ€™s native plants face an uncertain future. Many native plants, such as the exquisitely beautiful silverswords (below, photo from www.silverswordalliance.org) and lobeliads, now teeter on the edge of extinction.
