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