Stinging hairs of ongaonga

Stinging hairs of ongaonga

Ongaonga or tree nettle is covered in needle-like stinging hairs that give off a poison when brushed against. The sting is quite painful and the area around it may go numb for a short period. People have become sick or have died after blundering into a patch of tree nettle. The plant is common on bush margins and in regenerating scrub.
