General Species Information:
Found on Ellura (in the Murray Mallee, SA), the Riverland and elsewhere
Mature leaves here are ~6-10mm long, spines ~5mm long. The whole plant is ~400mm high. Spines are not in the same plane; they are oblique (hence the binomial name) to each other.
Difficult to see, but the thorns are twisted compared to the plane of the fruit. The spines can be somewhat hidden amoung the leaves as the mature leaves (at the base of the plant) are long compared to the length of the spines.
Tricky to separate from the S. brevifolia as the young leaves at the top of the plant can be similar in length (compared to the thorns/spines).
This plant is more hairy than O. brevifolia.

Also similar to Sclerolaena patenticuspis: Mature leaves here are ~5-10mm long, spines ~4-7mm long. The whole plant is ~200mm high. Spines are in the same plane.
