Hi all, Jim McKenny made the point that Tropaeolum and Oxalis are closely related in a recent mail. As it happens, I originally became interested in both of these genera as they were included within Geraniales by some authors. However, I fear we are both somewhat out of date today. In APGIII, they have been moved quite a long way apart. Tropaeolum are now placed in Brassicales (along with cabbages, would you believe!) and Oxalis are in Oxalidales. On the whole, I think I prefer the older model - but the probably just reflects my increasing age! Best regards, David Victor
