General Species Information:
Found on Ellura (in the Murray Mallee, SA) and elsewhere
We used to have this down as Euphorbia drummondii, then some years ago they split them into over 10 different species.
Dr Nathan Taylor said on iNaturalist "The plants can't be keyed without looking at seeds."
Since we've never collected the seed, we don't know which of this Anisophyllum section (a subset of the Euphorbia genus) they are.
Some current visual contenders, in the Murraylands Bioregion, are E. dallachyana, E. multifaria & E. verrucitesta. The other Euphorbia species are more erect, not prostrate.
