Timothy (Tim) John Entwisle (born 17 June 1960) is an Australian botanist, [2] much of whose research work is in phycology (algae). See for example the articles. [3] [4] [5] [6] He was awarded a Ph.D. from La Trobe University in 1986 for work on the taxonomy of Vaucheria . [7]
He was New South Wales’ Government Botanist in 2007 and 2008, [8] [9] and for eight years was the executive director of the Royal Botanic Gardens Sydney (2003–2011). [10] [11] Subsequently, he was director of Conservation, Living Collections and Estates, Kew, London from 2011, [12] [13] and from 2013 to 2023 he was director and chief executive of the Royal Botanic Gardens Victoria. [10] He is an honorary professorial fellow at the University of Melbourne and is currently (2020) president of the International Association of Botanic Gardens. [14]
As director of the Royal Botanic Gardens Sydney, Entwisle managed Sydney's Royal Botanic Gardens, the Mount Tomah Botanic Garden, in the Blue Mountains and the Mount Annan Botanic Garden, near Camden, [13] and at Kew, he was responsible for Kew Gardens, Wakehurst Place, and the Millennium Seed Bank. [13] A major project on taking up the Victorian appointment has been succession planning for the gardens under climate change. [15]
He values communicating with the general public as well as the scientific community. He is interviewed on radio frequently [16] [17] [18] [19] [20] [21] and had a program, Talking Plants, on ABC radio,, [22] which ran from December 2014 [23] to January 2016. [24] He is a regular contributor to the ABC radio program, Blueprint for living. [25] He also writes blogs on plants, [26] [27] and articles for Gardening Australia. [28]
In 2022, Tim was on the panel of expert judges for ABC's ‘Australia's Favourite Tree’ competition, where he appeared on episodes of ABC TV's show Catalyst. [29] He also helped select the short-listed trees for a public poll which drew 265,000 responses over three weeks and contributed to ABC's live blog [30] and various ABC radio conversations about the poll.
In the same year, Thames &Hudson published his memoir called ‘Evergreen: The Botanical Life of a Plant Punk’ [31] about his experiences as director of Royal Botanic Gardens in Sydney, Kew and Melbourne, as well as his life influences and perspectives, particularly about the role of public gardens. His love of garage music and algae feature in the early years, and there is a chapter on the very public removal of ten fig trees in Sydney during his time as director there.
He continues to publish in phycology. [32] [33] [34]

The algal genus, Entwisleia F.J.Scott, G.W.Saunders & Kraft, 2013, was named for him. [36] [37]

(incomplete)
Florideophyceae is a class of exclusively multicellular red algae. They were once thought to be the only algae to bear pit connections, but these have since been found in the filamentous stage of the Bangiaceae. They were also thought only to exhibit apical growth, but there are genera known to grow by intercalary growth. Most, but not all, genera have three phases to the life cycle. In the subclass Nemaliophycidae there are three orders, Balbianiales, Batrachospermales, and Thoreales, which lives exclusively in freshwater.
Thorea is a genus of fresh water algae in the division Rhodophyta. Thorea is a small alga with filaments up to 200 cm long, dark green in colour and not red as are marine Rhodophyta. The filaments have only as few secondary branches.
Conceptacles are specialized cavities of marine and freshwater algae that contain the reproductive organs. They are situated in the receptacle and open by a small ostiole. Conceptacles are present in Corallinaceae, and Hildenbrandiales, as well as the brown Fucales. In the Fucales there is no haploid phase in the reproductive cycle and therefore no alternation of generations. The thallus is a sporophyte. The diploid plants produce male (antheridia) and female (oogonia) gametangia by meiosis. The gametes are released into the surrounding water; after fusion, the zygote settles and begins growth.
Pediastrum duplex is a species of fresh water green algae in the genus Pediastrum. It is the type species of the genus Pediastrum.
Hildenbrandia is a genus of thalloid red alga comprising about 26 species. The slow-growing, non-mineralized thalli take a crustose form. Hildenbrandia reproduces by means of conceptacles and produces tetraspores.
Amphiroa is a genus of thalloid red algae under the family Corallinaceae.
Jania is a genus of red macroalgae with hard, calcareous, branching skeletons in the family Corallinaceae.
Clymene coleana, formerly known as Porphyra cinnamomea, is a red alga species in the family Bangiaceae. It is the only species in the monotypic genus Clymene. This species is endemic to New Zealand.
Sirodotia Kylin (1912) is a genus of freshwater red alga in the Batrachospermaceae family, found in temperate and tropical waters. It was first described by Kylin in 1912.
Christine Adair Maggs is a British phycologist. Formerly Executive Dean of the Faculty of Science & Technology at Bournemouth University, she was the first Chief Scientist of the Joint Nature Conservation Committee, retiring in 2022. She is now an independent non-executive Director of Ocean Harvest Technology https://oceanharvesttechnology.com/corporate-governance/board-of-directors/
Batrachospermaceae is a family of fresh water red algae (Rhodophyta). Genera within the Batrachospermaceae generally have a "Lemanea-type" life history with carpospores germinating to produce chantransia. Sporophyte phase with meiosis occurs in an apical cell to produce the gametophyte stage. Pit connections have two pit plug cap layers with the other layer enlarged. This family of freshwater red algae is uniaxial, meaning each filament with a single apical cell. The genera included within Batrachospermaceae are listed in the table below.
Michael Dominic Richard Guiry, is an Irish botanist, who specialises in phycology (algae). See for example the articles. He is the founder and director of the algal database, AlgaeBase.
Entwisleia is a monotypic genus in the red algae family, Entwisleiaceae. There is just one species in this genus, Entwisleia bella, from south-eastern Tasmania and represents both a new family and a new order (Entwisleiales) in the Nemaliophycidae.
Eva Konrad Hawkins was a Hungarian-born American biologist and college professor.
Neville Grant Walsh has worked at the National Herbarium of Victoria from 1977.
Donald Bruce Foreman was an Australian botanist who worked on the Monimiaceae and Proteaceae of Australia. He also helped with the editing of selected Flora of Victoria and Flora of Australia Volumes.
Greta Albrecht Fryxell was a marine scientist known for her work on the biology and taxonomy of diatoms. In 1996, she was elected a fellow of the American Association for the Advancement of Science.
Liagoraceae is a family of red algae (Rhodophyta) in the order Nemaliales. The type genus is LiagoraJ.V.Lamouroux.
Kathleen "Kay" Margaret Cole was a Canadian phycologist, known as one of the world's leading experts in the cytology of marine algae. In 1998 the Canadian Botanical Society awarded her the George Lawson Medal for lifetime achievement.
Batrachospermum is a genus of red algae from the family Batrachospermaceae. Due to its complex biological life cycle, descriptions of the taxon typically focus on gametophytes, while sporophytes, i.e., carposporophytes, are filamentous structures growing on the gametophyte, on which they depend. Independently living sporophytes have sometimes been described as separate species within the genus Chantransia. Additionally, differences may occur in the descriptions of the genus due to variations in taxonomic approaches, as new taxonomic techniques, as with other algae, result in changes in the assignment of individual species to the genus Batrachospermum. The genus is cosmopolitan, and its representatives are found in freshwater environments, mainly rivers, and less frequently in standing waters. These plants have thalli in the form of gelatinous-coated filaments.
