Scientific name: Prasophyllum wallum
Common name: Wallum Leek-orchid
Conventionally accepted as Prasophyllum wallum (CHAH 2010).
The Wallum Leek-orchid is a perennial orchid growing to 20–40 cm in height, with a single leaf. The species has a short flowering spike, 5–8 cm in length, upon which 12–18 flowers crowd at the top. Flowers are pale green and white, scented and large; growing to 11–14 mm in height and 7–9 mm in width. The white labellum (lip) is not strongly recurved, has a broad base, wavy edges, and a short, broad callus (Jones 1991b, 2006).
The Wallum Leek-orchid occurs from Hervey Bay to Coolum, or coastal areas in the Moreton and Wide Bay districts in south-east Queensland (Jones 2006; Queensland Herbarium 1989). The species relies on coastal wallum communities that occur disjointedly from Fraser Island in, Queensland, to northern New South Wales. As a result, the distribution of the species is fragmented (Queensland Herbarium 1989).
The Wallum Leek-orchid occurs in the Coolum Environmental Park (Briggs & Leigh 1996).
The Wallum Leek-orchid grows in wallum communities and on stabilised dunes. Associated species include Broad-leaved Paperbark (Melaleuca quinqinervia) and Swamp Banksia (Banksia robur) (Jones 1991b). The species is also known to be associated with the Queensland Regional Ecosystem 12.2.1, open or dry heath on Quaternary coastal dunes and beaches or sand plains with Leptospermum sp., Leucopogon sp., Wedding Bush (Ricinocarpos pinifolius), Strangea linearis, Daphne Heath (Brachyloma daphnoides), Small-leaved Geebung (Persoonia virgata), Grass Trees (Xanthorrhoea sp.), Green Five Corners (Styphelia viridis), Prickly Broom Heath (Monotoca scoparia), Snow Wreath (Woollsia pungens) and stunted Black She-oak (Allocasuarina littoralis) (Queensland CRA/RFA Steering Committee 1998a).
Flowering of the Wallum Leek-orchid has been recorded in August and September (Jones 1991b, 2006). Most Prasophyllum species reproduce by seed, and flowering may be stimulated by fire (Jones 1988). Leek orchids are all deciduous terrestrials with a subterranean tuber that is replaced annually (Jones 1988).
The main identified threat to Wallum Leek-orchid is clearing of habitat for urban development (Jones 1991b). The main potential threats to the species are hydrological changes and inappropriate fire regimes. Illegal collection may also be a potential threat to the species (Qld EPA 2007a).
Commonwealth Conservation Advice
Refer to the Commonwealth Conservation Advice (TSSC 2008th) for information on research priorities and recovery priority actions to mitigate threats including habitat loss, disturbance and modification, weeds and fire. Raising awareness of the species and enabling recovery of additional populations are also encouraged in the Advice.
