Elinor Frances Vallentin (formerly Nichol; (née Bertrand)[1] (1873, Falkland Islands – 1924, Plympton, Devon)[2] was a British botanist and botanical illustrator who made scientifically significant collections of botany specimens in the Falkland Islands.
She co-authored the book Illustrations of the flowering plants and ferns of the Falkland Islands in 1921 with Enid Mary Cotton, a fellow botanist.
[3] Vallentin grew up at Roy Cove and at Shallow Bay in West Falkland.
She collaborated with Arthur Disbrowe Cotton, supplying him with specimens, and enabling him to undertake the first comprehensive study of Cryptogams from the Falkland Islands.
[5][7] Vallentin also collaborated with botanist Charles Henry Wright collecting plants for him, supplying him with field notes and illustrations,[8] as well as illustrating his scientific paper The Mosses and Hepaticae of West Falkland Islands, from the collections of Mrs. Elinor Vallentin published in the Botanical Journal of the Linnean Society.
