Notes from the East African Herbarium: XII

Abstract

The account of the family Convolvulaceae for the 'Flora of Tropical East Africa' was practically finished in East Africa in 1958. Certain problems arose which were impossible to solve in Africa and completion was delayed. Whilst in England, I took the opportunity of working over all the East African material for a second time; this has meant the revision of several of my former opinions and, I regret, the changing of more names. A very large amount of fresh material becomes available every year and this naturally modifies one's views constantly.
