Description

Hawkweed is a soft-stemmed annual plant to 130 cm tall with most of the leaves growing around the base of the plant. The leaves are sometimes toothed, have a pointed tip, and are sparsely hairy with split-end hairs (the hairs divided into two for half their length). Leaves are 2.5 - 15 cm long and 4 - 30 mm wide. The small, yellow flowers grow in dense heads 8 - 10 mm wide at the ends of the stems.

Distribution

Known in NSW north from the Inverell area, in the north-western slopes and plains regions. It has been collected from Elsmore and Myall Creek (both near Inverell) as well as in Inverell, Oxley Park (Tamworth) and also from Dangar Falls in the Oxley Wild Rivers National Park in the northern tablelands of NSW. The species also occurs in the Darling Downs and Moreton regions of south-eastern Queensland.

Habitat and ecology

  • Where collected, the species abundance has been rare, locally occasional and locally frequent.
  • All recent collections appear to come from modified habitats such as weedy roadside vegetation and paddocks.
  • Its main habitat is open Eucalypt forest including a canopy of Eucalyptus melliodora, E. crebra, E. populnea, E. albens, Angophora subvelutina, Allocasuarina torulosa , and/or Casuarina cunninghamiana with a Dichanthium grassy understory.
  • Soils are black, dark grey or red-brown (specified as shallow, stony soil over basalt for one collection) and reddish clay-loam or medium clay soils.
  • The flowering and fruiting period is mainly October to January, with a few plants collected in flower or fruit until May.
