The Daubeny Herbarium in Oxford was the herbarium of the former Department of Forestry.
Miss Maureen Griffiths arrived there as Herbarium Assistant in 1952 and started work on her thesis, "The Taxonomy and Ecology of the African species of Terminalia", at the same time preparing the illustrations for this work.
In 1957 she left to start a career in free-lance illustrating.
Terminalia griffithsiana Liben was named in her honour.
