Dear Mary Sue, Whilst I greatly support the efforts that Kew and Mobot are making in putting together their list into a single resource, can I just offer a note of caution. I have just been looking at an area of interest to me: the genus Pelargonium. The list currently offered is, I am afraid, extremely deficient. Much of the work done by important authors in the past decade or so has just been totally ignored. For example, Betty Marais' total revision of Section Hoarea is completely omitted apart from a single species, even though many other species have been separately published in the South African Journal of Botany. best regards, David
