Pteronia paniculata ("Gombos" or "gum-bush") is a species of flowering plant in the family Asteraceae, indigenous to the Karoo regions of South Africa.
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]
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]
Pteronia is a genus of evergreen, woody perennial plants assigned to the family Asteraceae with currently 76 described species. Like in almost all Asteraceae, the individual flowers are 5-merous, small and clustered in typical heads, surrounded by an involucre of bracts. In Pteronia, the centre of the head is taken by relatively few, yellow, disc florets, while a ring of ligulate florets is absent. These florets sit on a common base.
