Description
edit
A small shrub with pale woody stem. The leaves are slender, blunt-ended, channeled and green.
One to three rounded, discoid flower heads appear at the tips of the branches. This helps to distinguish it from the otherwise similar species Pteronia paniculata.[2][3]
Distribution
editThis species occurs in the western Little Karoo, the western Great Karoo and into the Northern Cape Province.
It usually grows on lower slopes on silt or sand that is often calciferous (often overlying calcrete).
