The Frankston spider-orchid grows to 30 cm high, with a single leaf and one, rarely two, yellowish flowers with variable reddish stripes. This species is endemic to Victoria and in 2010 was known from only one population of approximately 40 plants at Rosebud on the Mornington Peninsula. Found in heathy grassy woodland, on deep, sandy, loamy soils, the Frankston spider-orchid emerges in cooler conditions and flowers in September and October, becoming dormant in the summer. Weed invasion is a threat to this species and fungus invasion and illegal collection are potentially threatening.

Fire Timing and potential In 1999; too frequent fires; or fires at the wrong time of the year (late frequency autumn; winter; spring) were a threat to this species (Backhouse et al.; 1999).
Too frequent fire or aseasonal fires may pose a threat by altering the habitat; removing organic surface materials and negatively impacting pollinators and mycorrhizal agents.
