Gamochaeta coarctata was originally from South America and is now the commonest of the naturalised spicate (inflorescence on a pike) cudweeds. It is common throughout the North Island, Nelson, Marlborough, Westland and Fiordland. Its habitat is wet or stony sites, river-beds, forest margins, lawns, pastures and coastal places.
Gamochaeta coarctata is a variable, rosette-forming annual or biennial plant. The shiny hairless basal leaves (2-11 cm long) have no stalk and are broadest towards the tip (2-11 cm long) These leaves undersides are covered in a white tomentose. (See photo)
