Typhonium johnsonianum is a species of plant in the arum family that is endemic to the Northern Territory of Australia.
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]
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]
NT Flora lists the species as "data deficient". [5] IUCN (2013) lists it as "vulnerable". [1]
Typhonium is a genus in the family Araceae native to eastern and southern Asia, New Guinea, and Australia. It is most often found growing in wooded areas.
Cycas armstrongii is a species of cycad in the genus Cycas, endemic to the Northern Territory of Australia. It is found from Darwin to the Mary River, the Finniss River in the west to the Arnhem Highway in the east, and north of Pine Creek. It also occurs on the Tiwi Islands and the Cobourg Peninsula.
Agathis atropurpurea, commonly known as the blue kauri, and occasionally as the black kauri or purple kauri, is a species of conifer in the very ancient plant family Araucariaceae. The family was distributed almost worldwide during the Jurassic and Cretaceous periods, but is now mostly confined to the Southern Hemisphere. This species is endemic to a small part of northeastern Queensland, Australia.
A not evaluated (NE) species is one which has been categorized under the IUCN Red List of threatened species as not yet having been assessed by the International Union for Conservation of Nature. A species which is uncategorized and cannot be found in the IUCN repository is also considered 'not evaluated'.
Shoal Bay is a shallow bay lying adjacent to, and north of, the city of Darwin in the Northern Territory of Australia. Encompassing Hope Inlet at its eastern end, it is characterised by extensive areas of intertidal mudflats and mangroves and is an important site for waders, or shorebirds. The bay is situated within the Shoal Bay Coastal Reserve, a protected area that was established in 2000.
The Black Jungle Conservation Reserve is a protected area in the Northern Territory of Australia near the territorial capital of Darwin. The rural area of Darwin and its development has a contrasting history to the more southern regions and their rural zones. The development of the rural area around Darwin occurred after 1950 as agricultural ventures were trialed. Prior to this the area was tropical savanna with pockets of monsoon rainforest and melaleuca swamps, unchanged for thousands of years, except by the traditional Aboriginal owners of the land who hunted and gathered and managed the landscape with fire. Black Jungle Conservation Reserve is a part of the Adelaide River Coastal Floodplain system which encompasses Black Jungle and Lambells Lagoon Conservation Reserves, Fogg Dam, Leaning Tree Lagoon Nature Park, Melacca Swamp and Djukbinj National Park. These Reserves encompass a range of wetland types and form part of the internationally significant Adelaide River floodplain.
