'''''Acacia enterocarpa''''', commonly known as '''jumping jack wattle''', is  a shrub species that is [[Biology:Endemism|endemic]] to eastern {{wipe|Australia}}.

==Description==
The shrub has a dense spreading habit and typically grows to a height of less than {{cvt|1.5|m}}. It has ribbed, red to brown coloured branchlets that are asperulate. The pungent, rigid, glabrous, green [[Biology:Phyllode|phyllode]]s are subsessile and patent to inclined. The phyllodes are straight to shallowly recurved and have a length of {{cvt|1.5|to|4.5|cm}} and a width of {{cvt|1|to|1.3|mm}} and have 10 to 12 distant raised nerves.<ref name=lucid/> It blooms between May and October<ref name=SA/> and produces simple [[Biology:Inflorescence|inflorescence]]s simple in groups of one to four situated in the axils. The spherical flower-heads have a diameter of {{cvt|3.5|to|4.5|mm}} and contain over 20 bright yellow flowers. The brown undulate seed pods that form after flowering have yellow margins. The coriaceous seed pods have a length of around {{cvt|2|cm}} and a width of {{cvt|2|mm}}. The dull dark brown to black coloured seeds in the pods have an oblong to elliptic shape and are around {{cvt|3|mm}} in length.<ref name=lucid>{{cite web|url=https://apps.lucidcentral.org/wattle/text/entities/acacia_enterocarpa.htm|title=''Acacia enterocarpa'' R.V.Sm.|accessdate=3 August 2019|work=Wattle - Acacias of Australia|publisher=[[Earth:CSIRO|CSIRO]] publishing}}</ref>

==Taxonomy==
The species was first formally described by the botanist R.V.Smith in 1957 as part of the work ''A remarkable new Acacia for Victoria (The "Jumping-Jack" Wattle)'' as published in ''The Victorian Naturalist''. It was reclassified as ''Racosperma enterocarpum'' in 2003 by Leslie Pedley then transferred back to genus ''Acacia'' in 2005.<ref>{{cite web|url=https://bie.ala.org.au/species/http://id.biodiversity.org.au/node/apni/2901643#names|title=''Acacia enterocarpa'' R.V.Sm.|accessdate=3 August 2019|work=Atlas of Living Australia|publisher=[[Organization:Global Biodiversity Information Facility|Global Biodiversity Information Facility]]}}</ref>
The [[Biology:Botanical name|specific epithet]] is derived from the Greek words ''entero'' meaning ''intestines'' and ''karpos'' meaning fruit in reference to the shape of the seed pod.<ref name=SA/> Both ''[[Biology:Acacia colletioides|Acacia colletioides]]'' and ''[[Biology:Acacia nyssophylla|Acacia nyssophylla]]'' are closely related to ''A. enterocarpa''.<ref name=SA/>

==Distribution==
It has a disjunct distribution through parts of south eastern South Australia and western Victoria. It is found on the southern tip of the Eyre Peninsula and Yorke Peninsula from around Curramulka and near [[Earth:Bordertown, South Australia|Bordertown]] extending eastwards as far as to Nhill in western Victoria.<ref name=lucid/> It is often found as part of woodland to open forest communities and grows in sandy alkaline soils as well as neutral yellow duplex to red porous loamy soils and grey cracking clay soils.<ref name=SA>{{cite web|url=http://www.flora.sa.gov.au/cgi-bin/speciesfacts_display.cgi?form=speciesfacts&name=Acacia_enterocarpa|title=''Acacia enterocarpa''|accessdate=3 August 2019|work=Electronic Flora of South Australia species Fact Sheet|publisher=Government of South Australia}}</ref>
