Guizotia jacksonii is a low, creeping, perennial plant with ovate leaves and yellow flowerheads belonging to the family Asteraceae.

[2] In 1902, Spencer Le Marchant Moore was the first to describe this species of sunfleck as Coreopsis jacksonii, based on a specimen collected by Frederick John Jackson from the Kiambu County in Kenya in 1899.

John Hutchinson assigned a plant collected by Battiscombe from the Aberdare Range in Nyandarua County to the genus Guizotia and called it G. reptans.

Earl Edward Sherff described in 1923 a plant from the western slopes of Mount Kenya, found by Mearns, as Bidens spathulata.

It wasn't until 1974 that J. Baagøe synonymised all of these names, and had to create the new combination Guizotia jacksonii to satisfy the International Code of Nomenclature for algae, fungi, and plants.
