Description

The Button Wrinklewort is a perennial, multi-stemmed herb, sometimes with narrow basal leaves and with leafy flower stems to 35 cm tall. Basal leaves are to 3.5 cm long and 1.5 mm wide. Flower-heads are bright yellow, slightly domed and button-like, to 2 cm wide. Flower-heads are produced at the ends of the stems in summer, and are surrounded at their bases by a cup of broad, overlapping, smooth bracts with light papery edges.

Distribution

Local populations at Goulburn, the Canberra - Queanbeyan area and at Michelago. Other populations occur in Victoria.

Habitat and ecology

  • Occurs in Box-Gum Woodland, secondary grassland derived from Box-Gum Woodland or in Natural Temperate Grassland; and often in the ecotone between the two communities.
  • Grows on soils that are usually shallow, stony red-brown clay loams; tends to occupy areas where there is relatively less competition from herbaceous species (either due to the shallow nature of the soils, or at some sites due to the competitive effect of woodland trees).
  • Exhibits an ability to colonise disturbed areas (eg. vehicle tracks, bulldozer scrapings and areas of soil erosion).
  • Normally flowers between December to March; plants do not usually flower until their second year.
  • Has regenerative buds at the surface of the soil but not below, so plants do not have the ability to resprout from underground structures; the stems usually die back in late summer or autumn and new basal leaves are evident by early winter.
  • Thought to be insect pollinated, although the specific vectors are not known.
  • Observed flourishing at a site a few years after the area was burnt by a wildfire.
  • Apparently susceptible to grazing, being retained in only a small number of populations on roadsides, rail reserves and other un-grazed or very lightly grazed sites.
