William Tietkens

[2] In 1889 Tietkens led his own expedition west of Alice Springs to the vicinity of the Western Australian border.

The expedition collected new species of plants and rock samples allowing the South Australian government geologist to compile a 'geological sketch' of the country traversed.

Tietkens was elected a fellow of the Royal Geographical Society on his return.

Specimens of 250 plant species were collected, although only 8 were new to science,[4] and in 1890, Ferdinand von Mueller and Ralph Tate named Eremophila tietkensii in his honour.

[5][6] Tietkens later worked for the New South Wales Department of Lands as a surveyor from 1891 until his retirement in 1909.
