Adenium from Saudi Arabia

While preparing a talk for a conference in October on camels, I came across a very useful website maintained by Professor Jacob Thomas of the Herbarium in the Department of Botany & Microbiology at King Saud University in Riyadh. This is Plant Diversity in Saudi Arabia, with sections on topography, vegetation, flora, the history of botanical studies, conservation, and a major bibliography. There is also a checklist of species recorded.
