Synonyms: Senecio sceleratus Schweick.
Common names: Noxious ragwort (English)
Frequency: Common
Status: Native
Description:
Erect herb, growing annual stems from a perennial rootstock. It belongs to a group of closely related species, including S. venosus, S. retrorsus and S. pergamentaceus. All are erect perennial plants with glaucous, elliptic leaves, which clasp around the stem. S. latifolius lacks the clear translucent veining when held against the light.
Notes: The new shoots appear after winter when grass cover is short and it is therefore likely to be grazed by lifestock. This can have serious consequences as the plants contain a cumulative poison, which has proven deadly to cattle and horses. The toxin is a pyrrolizidine alkaloid which cause acute or chronic liver toxicity resulting in necrosis and cirrhosis (chronic cases) of the liver. The disease condition is known as seneciosis, or Molteno straining disease in cattle, while in horses it is often called 'dunsiekte' (slim disease).
