Early life and education

Baylis was born in Palmerston North to Gerald Baylis, an agricultural scientist, and his wife Daisy (Kathleen Daisy Baylis (nee Aston), sister of New Zealand botanist Bernard Aston).^[1][2] The family moved to Campbells Bay on Auckland's North Shore in 1920, where Geoff and his sister Geraldine attended Takapuna Primary School and were then some of the first students at Campbells Bay School.^[1][3]

Geoff attended Takapuna Grammar School before enrolling at the University of Auckland (then Auckland University College) in 1931.^[1] In 1935, he earned his MSc on the ecology of the mangrove Avicennia resinifera (now Avicennia marina subsp. australasia) with a thesis entitled, "Some observations on Avicennia officinalis Linn in New Zealand".^[4][5][1] In 1936, a scholarship enabled Baylis to attend London Imperial College where he gained his PhD in 1938 in Plant Pathology.^[4][6][1] His PhD thesis was entitled, "The influence of certain fungi on the germination of peas; and, A physiological study of the pathogenicity of several species of Sclerotinia".^[6]

On returning to New Zealand, Baylis joined the

The annual Geoff Baylis Lecture was established by the Botanical Society of Otago in 2002 to honour his contributions to the society and field of botany.^[9] Geoff Baylis was the speaker at the inaugural lecture in 2002, and as of 2022 there have been a total of 20 different lectures and speakers in the intervening years.^[13]

The standard author abbreviation G.T.S.Baylis is used to indicate this person as the author when citing a botanical name.^[14]

Eponymy

The following species of plants and fungi have been named in honour of Geoff Baylis:

• The critically endangered tree, Pennantia baylisiana (W.R.B.Oliv) G.T.S.Baylis, or Three Kings kaikōmako.^[15]
• The
  liverwort Plagiochila baylisii Inoue & R.M.Schust., which was thought to be endemic to Fiordland, South Island, New Zealand^[16] but is also known from Tasmania, Australia.^[9][17]
• The critically endangered
  E. Horak) J.A. Cooper (originally described by Egon Horak in 1971 as Nivatogastrium baylisianum E. Horak).^[19]

In his younger years, Baylis was an avid mountaineer and took part in several climbing trips to the Southern Alps. In 1965 he and his climbing companions had to be rescued by plane after being trapped by bad weather on the Volta Glacier.^[1]

Baylis flatted in, and later bought, the historic Dunedin house "Threave" in upper High Street, a Robert Lawson-designed house which he fully restored, as well as extending the building's woodland surrounds. He became a collector of art and antique silverware and porcelain, and was a regular attendee at classical music concerts.^[1] He also had an extensive garden which contained both native and exotic species.^[9]

Geoff remained unmarried throughout his life, but kept close ties with his sister Genevieve Chamberlain and her family. He moved back to Campbells Bay, next door to the original family home (which he had bought and restored for his nephew Geoffrey Chamberlain). He died there on New Year's Eve, 2003, at the age of 90.^[1]
