[5] Dianella tasmanica was first described in 1858 by eminent English botanist and explorer Joseph Dalton Hooker.

[6] Dianella tasmanica is a strappy herbaceous plant which grows to 0.5–2 metres (1–7 ft) high and wide, with a thick spreading rhizome under the ground.

The green linear keeled leaves have finely toothed margins, and may reach 1 m (40 in) in length and 1.5–4 cm wide.

[6] Found southwards from Dorrigo in New South Wales,[7] and into Victoria and Tasmania, Dianella tasmanica grows singly or in clumps in shady spots in wet forests.

They are markedly larger than the fruits of other Dianella species, and produce an irritating tingling sensation in the mouth when consumed.
