Over the years, she provided him with specimens collected in Cornwall as well as those from abroad that came into Britain through Falmouth. She is credited (as ``Miss Warren'') as one of 19 plant specimen collectors to whom Hooker is particularly indebted in the preface to his 1841 Manual of the British Algae. In his history of British seaweeds, Phycologia Britannica, Hooker lists an algae named after her by the botanist Robert Caspary, Schizosiphon Warreniae (now Rivularia biasolettiana).
