Leporella fimbriata is a terrestrial, perennial, deciduous, sympodial herb with a few inconspicuous, fine roots and an oval-shaped tuber lacking a protective sheath.

Unlike those in some other orchids, the droppers are produced well away from the parent tuber at the end of long, root-like stolons.

The other two petals are erect, 10–12 mm (0.4–0.5 in) long, narrow, linear in shape but with a club-like end which has many glandular hairs.

[3][4][5][6][7]This orchid was first formally described in 1840 by John Lindley who gave it the name Leptoceras fimbriata and published the description in A Sketch of the Vegetation of the Swan River Colony.

[12]: 355 Leporella fimbriata usually grows in woodland or shrubland but is also found in heath and near areas that are swampy in winter.

[6] This orchid is a myrmecophyte and is pollinated by a male bull-ant (Myrmecia urens, Family Formicidae) when the ant attempts to copulate with the labellum.
