Ethel Sarel Gepp, also publishing as Ethel Sarel Barton (21 August 1864 – 6 April 1922),[1] was a phycologist who specialized in the study of marine algae and is noted for her work reordering the genus Halimeda.
Ethel Sarel Barton was born at Hampton Court Green in England.
[1] Gepp worked as a specimen collector for the Department of Botany at the British Museum (Natural History) and for Kew Gardens, and she contributed papers to the Journal of Botany, the Journal of the Linnaean Society, and other scientific publications under both her birth and married names.
[1][2][3] In 1900, she published the first of a number of papers on the macroalgae genus Halimeda, working with a collection of specimens that had been brought back from Funafuti Atoll in the South Pacific.
[4] A contemporary review praised her thorough work on this genus, which "has been the despair of every phycologist for years".
