# Gordon Rowley

Gordon Douglas Rowley (1921–2019) was a British botanist and writer specialising in cacti and succulents.

## Personal life

Rowley was born on 31 July 1921 in London, UK to Cecil and Florence Gladys (née Goldsworthy) Rowley. He went to The Lower School of John Lyon, Harrow-on-the Hill. In 1942 he graduated with a B.Sc. degree in botany from King's College, University of London.
He died 11 August 2019.

## Career

From 1948 to 1961 Rowley was employed at the John Innes Horticultural Institution while it was based at Merton Park to curate the National Rose Species Collection and subsequently all the plant collections. From 1961 to 1981 he was lecturer in Horticultural Botany at the University of Reading.
Cacti and succulents had been one of Rowley's interests since the mid-1940s but they became the focus of his life. He travelled extensively to see and collect cacti and succulents in Africa and southern America. He developed his own collection of these plants as well as antiquarian books about this group. He was a founder member of the International Organisation for Succulent Plant Research, and from 1952 to 1982 edited the society's Repertorium Plantarum Succulentarum, a list of new succulent plant names published each year. Rowley was the inaugural President of the British Cactus and Succulent Society in 1983 and continued in this role until 2004. He was also the editor of the society's journal Bradleya from 1993 to 2000.
