Dendrobium bigibbum was described by Lindley in 1852 following collection by Dr. John Thomson in 1849 from Mt. Adolphus Island, Australia, in the Torres Strait. Various taxonomic classifications and more than 40 different names were applied to the Den. bigibbum complex over the next 125 years. Most were based on one or a few plants. This month features a thorough discussion of the complex by Peter Adams including new classification and hybrid registration schemes. Also in this issue David Rosenfeld, MD continues his series on the historical figures in the orchid world with an introduction to James Bateman and Soraya Cates Parr discusses Goodyera pubescens, one of the rattlesnake plantains found in the eastern United States.
