E. tannensis subsp. tannensis Contents | |
Euphorbia tannensis is a species of herb or shrub native to Australia and some Pacific islands.
It grows as an erect annual or perennial herb or shrub, from 10 centimetres to a metre in height, with green or yellow flowers. [1] It often appears spindly due to its leaves being deciduous. [2]
This species was first published by Curt Polycarp Joachim Sprengel in 1809, based on a specimen collected by Georg Forster in . In 1977 two species, E. eremophila and E. finlaysonii, were submerged within E. tannensis as E. tannensis var. eremophila and E. tannensis var. finlaysonii respectively, these being treated as varieties of a new subspecies, E. tannensis subsp. eremophila. [2] [3]
This species is widespread on the Australian mainland, occurring in every mainland state, though only in the far north-west corner of Victoria (Australia). [2] It is widely reported as occurring only in Australia; [4] yet the type specimen was collected on Tanna in what is now Vanuatu, and it has also been recorded in New Caledonia. [5]
Eucalyptus eremophila, commonly known as the sand mallet or tall sand mallee, is a species of mallet that is endemic to semi-arid regions of Western Australia.

Eremophila alternifolia, commonly known as narrow-leaved poverty bush, is a plant in the figwort family, Scrophulariaceae, and is endemic to areas between the far west of New South Wales, the far south of the Northern Territory and the southern half of Western Australia. It is a variable shrub, with respect to its growth form, leaf shape and flower colour. Aboriginal Australians used the leaves to treat ailments such as colds and skin infections and pharmacological testing has shown that the leaves contain compounds that affect cardiac activity.

It is a spreading, weeping shrub or small tree with long, strap-like leaves. Its leaves are among the longest in the Eremophila genus and the flowers are also relatively large, reflecting their adaptation to pollination by birds.
Eremophila latrobei, commonly known as crimson turkey bush, native fuchsia, Latrobe's emu bush, grey fuchsia bush, warty fuchsia bush and Georgina poison bush is a flowering plant in the figwort family, Scrophulariaceae and is endemic to Australia.
