This month Laura Bonnell continues her series on the Dendrobium bigibbum complex, discussing the development of modern den-phals (those full, round-flowered hybrids that are so popular in the marketplace) and the intrasectional hybrids between bigibbum and its various forms and the other species in Dendrobium section Phalaenanthe.  Robert Fuchs, of R.F. Orchids, discusses the quest for large-flowered red vandas and Jean Allen-Ikeson presents the development of white cattleyas.
