Scientific name: Prasophyllum morganii

Common name: Mignonette Leek-Orchid

Other names: Cobungra Leek-orchid; Dense Leek-orchid

Conventionally accepted as Prasophyllum morganii (CHAH 2010). The Mignonette Leek-orchid has been confused with the Congested Leek-orchid (Prasophyllum retroflexum) which is found in Kosciusko National Park near Kiandra in New South Wales and Alpine National Park in Victoria. The two species were initially considered synonymous, but it is now established that the Mignonette Leek-orchid is a Victorian endemic (Backhouse & Jeanes 1995; McDougall & Walsh 2002).

The Mignonette Leek-orchid is a small terrestrial herb with a single leaf 120–200 mm in length and 3–5 mm in width, reddish at the base that stands erect but is usually withered by the time the species flowers. A single green to reddish flower stem, up to 250 mm high, holds a densely crowded 50–80 flowers. Flowers are flattened in appearance, 8–9 mm in width, 7–8 mm in length and green with tones or stripes of dark purple. The labellum (lower lip) is reflexed (abruptly turned backwards) and has irregular crinkling along the edges. The flowers are sweetly scented (Backhouse & Jeanes 1995; Bishop 2000; Jones 2006).

The Mignonette Leek-orchid was recorded three times from one site (approximately 15 individuals) near Cobungra, Victoria (Coates 2003f). The species has not been recorded since 1933 and is considered to have been highly localised (Coates 2003f). The type locality of the species and surrounding suitable habitat has been well surveyed (Coates 2003f).

The Mignonette Leek-orchid occurs in Snow Gum (Eucalyptus pauciflora subsp. pauciflora) open forest at approximately 1000 m above sea level (Backhouse & Jeanes 1995). The type locality occurs on the northern side of a small ridge running down to a creek. Soils are clay, with small amounts of quartz and sandstone (Nicholls 1930 cited in Coates 2003f).

The Mignonette Leek-orchid was recorded flowering from November to January (Backhouse & Jeanes 1995).

The Mignonette Leek-orchid occurred on private property that has subsequently undergone pasture improvement and cattle grazing. Threats included weed invasion, grazing, degradation of habitat from cattle and possible inappropriate fire regimes (Vic. DSE 2003ad).

Management documents for the Mignonette Leek-orchid are at the start of the profile.

The following table lists known and perceived threats to this species. Threats are based on the International Union for Conservation of Nature and Natural Resources (IUCN) threat classification version 1.1.
