Oncosiphon pilulifer

Oncosiphon pilulifer, also known as globe chamomile and stinknet,[2] is a flowering plant in the daisy family (Asteraceae) native to South Africa and Lesotho.

Globe chamomile is a straggly, branching annual plant with a strong smell, growing up to 2 ft (60 cm) tall.

Wind-borne seed transportation spreads the plant which takes root in sunny, disturbed soil in natural and cultivated areas.

[4] The Arizona department of Agriculture considers it a "high priority pest for quarantine, control or mitigation if a significant threat to a crop, commodity, or habitat is known to exist.

"[6] Other problems are its density which displaces native vegetation, the high flammability of dried-out patches, and the caustic smoke produced when it burns.
