Yes Diane, but Jones isn't listed as the one naming those genera starting with Jones. Szlachetko is a Finnish botanist and it seems that in spite of naming two genera starting with Jones that he and Jones are not in agreement about all the orchid changes. Also you will be interested to know that there is this one: Davejonesia named by M.A. Clem for some species once considered Dendrobium I don't see any named starting with Clem however. David Jones gave the key note speech at a several day Symposium on Australian plants I attended many years ago at the Arboretum at the University of California at Santa Cruz. They have an amazing selection of Australian plants growing at the Arboretum and the Symposium was wonderful. At this late date I can't remember what I learned but it obviously made a big impression on me as I have a number of Australian plants in my garden as a result. Jones gave talks on Australian rain forests, cycads and a third on Australian orchids. He and Rodger Elliot have been writing the Encyclopedia of Australian Plants suitable for cultivation. They started in 1980 and the last volume I've seen was Volume 8 through So. Can you imagine all the corrections in names they will need to make when they have finished the alphabet? They will probably need two volumes just for the changes. Here's what I found about David Jones: "David Jones is renowned in Australia and overseas for his botanical and horticultural work on Australian plants. His studies of the specialist fields of ferns, orchids, palms and cycads have vastly improved our understanding of these unique plant groups. He has published many scientific papers on this group of plants. David has travelled extensively throughout Australia in his search for knowledge and he continues to photograph many rare and unusual species from remote areas. He is presently a research scientist at the Centre for Plant Biodiversity Research at CSIRO. " Mary Sue
