Ilma Grace Stone (1913 – 2001), née Balfe, was an Australian botanist who specialised in bryology. She was an author, collector, and researcher of Australian mosses, a subject on which she lectured and wrote.

Scientific career

Stone studied at the Department of Botany in University of Melbourne from 1930 - 1934, graduating with an MSc involving a thesis on sclerotia-forming fungi that cause disease in ornamental plants. However, she did not begin her career studying bryophytes until 1957 when she was appointed as a demonstrator in the Department of Botany at University of Melbourne, at first part-time and then full-time. Her PhD was awarded in 1963 for A morphogenetic study of stage in the life-cycle of some Victorial cryptograms. She was awarded a D.Sc. by the University of Melbourne where she was an Honorary Research Fellow when she was 76. She officially retired from the university in 1978 but continued to research and publish until her death in 2001.

She was initially interested in ferns but from 1969 specialised in mosses. In 1983 she published a description of a new species, Fissidens gymnocarpus, and continued to contribute to moss taxonomy. She is noted for keen observation and attention to often small and overlooked moss species, and for her contributions to their taxonomy. She was also an impressive field bryologist. Stone is credited with significantly increasing knowledge of mosses in Australia, especially those in Queensland.

She was particularly expert in the genera Acaulon, Pleuridium, Eccremidium, Astomum and Nanobryum as well as the moss floras of Victoria and Queensland, the tropical mosses of Australia and those with permanent protonema. In addition, her work on the Australian Fissidens in collaboration with David Catcheside made significant improvements to its taxonomy.

Awards

In 1989 she was awarded a D.Sc. by the University of Melbourne where she was an Honorary Research Fellow.

She was elected an Honorary Member of the British Bryological Society in 1982.

Several species of moss have been named in her honour. This includes two genera (Stonea and Stoneobryum) and two species:

  • Stonea oleaginosa (I.G. Stone) R.H. Zander Phytologia 65:432.
  • Stoneobryum bunyaense D.H. Norris & H. Robinson Bryologist 84: 96.
  • Stoneobryum mirum (Lewinsky) D.H. Norris & H. Robinson Bryologist 84: 98.
  • Macromitrium stoneae Vitt & H.P. Ramsay J. Hattori Bot. Lab. 59: 400.
  • Syrrhopodon stoneae W. Reese Bryologist 92: 302.

Early education and personal life

She was born in Brunswick, Victoria in Australia in 1913 and was educated at Ivanhoe Girls Grammar School, financed by a scholarship. She excelled in English and Botany. After gaining her MSc degree from University of Melbourne, rather than continue her studies at University of Cambridge in the UK, she chose to marry. She was married to Alan Stone and they had three children. For the first 20 years of her marriage her family took precedence over her career
