Atriplex fissivalvis, commonly known as gibber saltbush, is a plant species in the family Amaranthaceae, subfamily, Chenopodioideae.[2] It occurs in the Australia n states of South Australia, New South Wales, Queensland and the Northern Territory.[5][6][7][8]
Description
Atriplex fissivalvis is an annual monoecious herb 10–30 centimetres (4–12 in) high, which branches from the base.[7] The leaves (on a stalk of 5–10 millimetres (0.2–0.4 in)) are about 20 millimetres (1 in) long, with toothed or sinuate margins and an acute apex.[5][7] It flowers in clusters[2] in the axils of leaves,[7] from June to November (in the Northern Territory).[8] Fruiting is from June to November (in the Territory),[8] and the fruit is without a stem and enclosed in bracteoles.[7]
Distribution
In the Northern Territory it is found in the IBRA regions of Finke, MacDonnell Ranges, Simpson Strzelecki Dunefields, and Stony Plains.[8]
Taxonomy & naming
Atriplex fissivalvis was first described by Mueller in 1875.[2][3] The specific epithet, fissivalvis, comes from the Latin, fissus (cleft) and -valvis (-valved), giving "split-valved".[9]
Similar taxa
"Atriplex fissivalvis could be confused with A. lobativalvis, however the latter has fruiting bracteoles that lack appendages on the dorsal surface, are prominently keeled or have a raised area on the lower dorsal surface, have margins that are fused for over one-third their length, and has a preference for freshwater swamps and claypans."[8]
Conservation status
The Northern Territory lists this species as "Near Threatened" under the TPWCA act.[8]
