Cover: Bruce Bayer photographed this plant of Drosanthemum hallii L.Bolus in habitat S.W. of Worcester (Hartmann & Bayer 34610) in full bloom and with the unusual change in colour from a yellow base to almost red tips. D. hallii has been described with pure yellow petals. The black filamentous staminodes, typical of Drosanthemum subgenus Speciosa, become more visible with age; various stages are shown here.
