A true pioneer

Walking in the Constantia Greenbelt today, I came across this flowering Gonnabos (Passerina corymbosa). It is an interesting wind-pollinated, pioneer species that is dealt with in some detail on the Plantzafrica website.
A close-up reveals the tiny open flower with eight pollen-laden stamens. Shake the branch and a cloud of pollen puffs off the plant.
More pollen-laden stamens.
The young stems are white and hairy.
The Gonnabos's ability to extract soil moisture from deep underground enables it to survive harsh conditions and its root system is excellent for stabilizing sandy soil.
