Description
Detail of the clusters of flowers
Detail of slender green leaves, and dried flower sheaths

This aromatic species has sticky leaves but, unlike some other Pteronia species, the flowers are not sticky. It has slender, furrowed, needle, incurved, green leaves, held in opposite pairs.

It forms clusters of flowers (several capitula) at the tips of its branches. This helps to distinguish it from the otherwise similar species Pteronia pallens.[1][2]

Distribution
Adult bush in habitat

This species is widespread, occurring from Namibia to the Robertson Karoo in the south, as well as eastwards into the Eastern Cape.

Its natural habitat is dry, rocky apronveld and it is extremely common. Due to its being inedible for livestock, it achieves unnatural densities in areas that are overgrazed.

It often cooccurs with its close relatives, Pteronia pallens or Pteronia incana.[3][4]

gollark: In a few years I think it'll be back on dedicated accelerator cards anyway.
gollark: Nvidia added real-time raytracing stuff to distract from the lack of significant generational price/performance improvement (because of poor competition in the market), and machine learning stuff for some reason, and then hyped them so much that they threw out stuff like "sanity" and "consistent branding".
gollark: AMD's got a 5700 XT "Anniversary Edition", though...
gollark: Nvidia's done it stupidly *too*! It goes GTX 9x0 (Ti) → GTX 10x0 (Ti) → RTX 20x0 (Ti) + GTX 16x0 (Ti) (in the same generation) → now some of them have "Super" variants for some reason and some are being replaced by the super versions but some aren't.
gollark: The prices seem to be weirdly shifted in Australia.
