Thistle Yolette Harris
Australian botanist (1902-1990)

Thistle Yolette Harris (29 July 1902 – 5 July 1990), was born as Yolette Thistle Harris, but mostly known as Thistle Stead, was an Australian botanist, educator, author and conservationist.
Biography
She was one of three daughters born to Charles Thomas Harris and Illma Richardson Harris (née Rokes). She was educated at SCECGS Redlands, Cremorne, where she was taught by the English teacher, Constance Le Plastrier (1864–1938), who was a member of the Naturalists Society of New South Wales and co-author of Botany for Australian Students (1916), and helped foster Harris' interest in native plants. Harris died in 1990 at a nursing home in Summer Hill, New South Wales.
Education
Harris studied botany at the University of Sydney, graduating with a degree in botany in 1924 followed by a diploma of education in 1925 from Sydney Teachers College. After several years as a science teacher in secondary schools, she became a lecturer in science education at Sydney Teachers' College (1938–61). In 1945 she was awarded a Master of Education degree from the University of Melbourne and studied for a Diploma in Landscape Design at the University of New South Wales between 1968 and 1969. Harris later featured her efforts to revegetate the mine-workings at the Central Mine of the Sulphide Corporation in her book Australian Plants for the Garden (1953). Harris also lectured on Biological Science at University of Sydney and on Botany at Sydney Technical College.
According to John Walter, her interest in Australian plants was also developed when she met Albert Morris (1886-1939) while she taught at the school in Broken Hill between 1929 and 1930.

Why this record matters
The phrase “australian botanist (1902-1990)” supplies a clear boundary for inquiry. It also exposes the unanswered questions: who defined that boundary, when it became stable and which sources sit outside it.
The citation trail is more important than the brevity of the summary: it shows where individual claims can be examined in context. The source revision retrieved here is dated Aug 29, 2026. The linked authority identifier is Q7786486. VIAF identifies the subject as 66536454. The Library of Congress control number is no2023084531. 3 of 3 selected statements include explicit references; 0 carry qualifiers and 0 use preferred rank. The first chronological checks are 1902, 1990, 1864 and 1938.
A concise general-reference account can conceal disagreements about scope, terminology or the weight assigned to individual sources. The lead is largely declarative, so disagreement and counter-evidence require a deliberate search beyond the opening account. Authority statements aid reconciliation but still require their own references, qualifiers and ranks to be checked.
