On the cover: The Orange River, which forms part of the border between South Africa and Namibia can be seen behind this Bulbine ophiophylla. The picture was taken in 2003 by your Editor at Kortdoringberg, a 400m outcrop about 25km E of Alexander Bay, while on a tour guided by Graham Williamson. Graham's article on Bulbine in this Journal is perhaps the most significant work on the genus as a whole this century.
