Janet Louise Cosh (21 April 1901 – 22 October 1989) was an amateur botanist, botanical collector and secondary school teacher.
[1] An only child, she was educated at Normanhurst School for Girls (1914–1918) before studying English, history and classics at the University of Sydney.
[2] Although not trained as a botanist, Cosh collected 1,600 specimens and made nearly 2,000 botanical illustrations of plants she found in the Southern Highlands and Illawarra regions of New South Wales.
[5] Another bequest enabled the creation of the Janet Cosh Memorial Room at the visitors centre at Fitzroy Falls through the Foundation for National Parks and Wildlife.
The room holds specimens of local flora and copies of some of Cosh's botanical illustrations.
