Scientific name: Irenepharsus magicus
Conservation status in NSW: Endangered
Commonwealth status: Not listed
Profile last updated: 17 Aug 2018


Elusive Cress is an erect annual or biennial herb, growing to almost 1 m tall. Its basal leaves do not remain on the plant; its stem leaves reduce in size and number up the stem. The small, white, four-petalled flowers grow in an elongated spray. It is distinguished from the other Irenepharsus species in NSW (I. trypherus) by having sparsely hairy leaves, a dry pod more than 1 mm wide and seeds with a half wing on the margin.


Although the location information provided with the single NSW collection is vague, it would appear that it was made in the vicinity of Geehi Dam, which is within Kosciuszko NP. Elusive Cress has also been recorded in East Gippsland in Victoria.

Habitat and ecology

  • Habitat preference for the species is unclear, although two collections in Victoria have been made in or on the edge of recently logged Messmate Stringybark (Eucalyptus obliqua) forest. One of these sites had been burnt. The record of the species in NSW includes the habitat note "growing on mineral soil of embankment". The species was recently found in a rocky limestone area in eastern Victoria after the 2003 fires.
  • Flowering collections across the range of the species have been made between December and April, the single NSW collection being made in April (1954).
