Typhonium johnsonianum is a species of plant in the arum family that is endemic to the Northern Territory of Australia.

Description

[edit]

The species is a deciduous geophytic, perennial herb, which resprouts annually from a hemispherical, cream-coloured corm. The oval, dull light green leaves are 3.5 cm long by 1.7 cm wide, on a 4 cm long stalk. The flower is enclosed in a green, brown and maroon spathe 5 cm long, appearing in December.[3]

It was named after Australian botanist L.A.S. Johnson after his 70th birthday.[4]

Distribution and habitat

[edit]

The species is only known from the tropical Top End of the Northern Territory. Only two localities are known, at Black Jungle Conservation Reserve and in Kakadu National Park.[4]

The type locality is an open grassy clearing between Acacia auriculiformis / Melaleuca forest and Lophostemon lactifluus forest, near the edge of a floodplain, in well-drained sandy soil with a high water table during the wet season.[3]

Conservation status

[edit]

NT Flora lists the species as "data deficient".[5] IUCN (2013) lists it as "vulnerable".[1]
