Lazarum praetermissum

Typhonium praetermissum is a species of plant in the arum family that is endemic to the Northern Territory of Australia. [3] In 2022, Hay and others resurrected the genus, Lazarum, and renamed the species as Lazarum praetermissum [4] (a name accepted by Plants of the World Online). [5]

The species is a geophytic, perennial herb, which resprouts annually from a corm. The leaves vary from oval in shape to deeply divided, up to 4.5 cm long, on a stalk up to 5.5 cm long. The flower is enclosed in a brown and maroon spathe 4 cm long. The small fruits appear in November and December. [3]

Distribution and habitat

The species occurs in the tropical Top End of the Northern Territory, with a range limited to the vicinity of Darwin and the Litchfield shire including Middle Arm, Virginia, Karama, Noonamah, the Palmerston escarpment and Mandorah. [6] Many sub-populations are under increasing pressure from development and weed incursion. [7]

It is found mainly in open woodland habitats with red-brown clay or lateritic soils, [3] typically in Eucalyptus miniata woodland on well drained soils, and on the margins of plateaus. [7]

Conservation status

NT Flora lists the species as "vulnerable". [8]

<i>Cycas armstrongii</i> Species of cycad

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.

Typhonium mirabile is a species of flowering plant in the family Araceae. It is found growing in Australia in eucalypts woodlands at the base of Cycas plants. It was first described in 1992 by Alistair Hay, as Lazarum mirabile and was the only species in the genus Lazarum. In 1997, Hay published a paper transferring it to the genus Typhonium.

<span class="mw-page-title-main">Shoal Bay (Darwin)</span> Bay in Beagle Gulf, Northern Territory

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.
