Richard Arnold Dümmer

Dümmer worked in the herbaria and libraries of Kew, the British Museum, the Linnaean Society, Cambridge, Oxford and Edinburgh Universities.

He published taxonomic notes on Agathosma, Eugenia, Bruniaceae, Alepidea, Lotononis, Pleiospora, Combretaceae, Adenandra and Acmadenia.

He was employed by the Kivuvu Rubber Company of Kampala in 1914, using the opportunity to collect flowering plants and fungi.

Dümmer then spent a year back in Cape Town identifying and processing his collections.

He is commemorated by the Kew Guild's annual award of "The Dümmer Memorial Prize" to the student submitting the best collection of British plants.
