​Leptorhynchos elongatus (lanky buttons) is a perennial herb in the daisy family. It is known in Tasmania from two cemeteries in the Southern Midlands, together occupying only 0.5 hectares, and one site on the Central Plateau where only a few plants have been seen to date. The species grows in grasslands or grassy shrublands, mostly on Tertiary basalt, and is believed to have suffered a significant decline since European settlement due to habitat clearance and browsing by stock. Plant numbers can fluctuate, with recruitment probably from freshly shed seed only, and recruitment only occurring in patches of bare ground. This puts the small Tasmanian occurrences at particular risk from losses from chance events and weed invasion, combined with successive years of browsing or mowing/slashing that reduces seed production, a lack of gap-forming disturbance to provide recruitment niches, and unfavourable climatic conditions for germination and seedling establishment.

  • Flowers are required to identify and aid detection of this perennial herb from the daisy family. Surveys for the species should ideally be undertaken during the early stages of its flowering period, October to November. Detection of the species at lowland sites becomes increasingly difficult later in the season due to the obscuring growth of native grasses such as Themeda triandra (kangaroo grass) or Austrostipa species (speargrasses). Herbarium specimens have been collected from October to early January.
  • In Tasmania, the species is known to be extant at two cemeteries in the Southern Midlands where it occurs on Tertiary basalt or Quaternary sediments in Themeda grassland, as well as from open grassy shrubland at a higher altitude site at Liawenee Moor on the Central Plateau. There are also two 19th century collections from the Northern Midlands.

Permit: A permit is required under the Tasmanian Threatened Species Protection Act 1995 to 'take' (which includes kill, injure, catch, damage, destroy and collect), keep, trade in or process any specimen or products of a listed species. Additional permits may also be required under other Acts or regulations to take, disturb or interfere with any form of wildlife or its products, (e.g. dens, nests, bones). This may also depend on the tenure of the land and other agreements relating to its management. ​​​​​
