On the cover: Embedment is not merely for moles and reporters; Conophytum has practised it for years, as demonstrated by Chris Barnhill's photos of C.maughanii subsp. armenianum (Augrabies, SH 365, front) and C.lydiae (Geselskapbank, SH 1290, back). Matthew Opel's anatomizing papers in this issue (pp 27-77) cast new light on the genus.
