It has a single tubular leaf and between twelve and thirty scented yellowish, reddish or brownish flowers and is only known from a small area in the south of the state. DescriptionPrasophyllum barnettii is a terrestrial, perennial, deciduous, herb with an underground tuber and a single tube-shaped leaf up to {{convert|120|mm|in|sigfig=1|abbr=on}} long and {{convert|2-3|mm|in|sigfig=1|abbr=on}} wide at the base. Between twelve and thirty scented yellowish, reddish or brownish flowers are arranged along a thin flowering spike {{convert|70-120|mm|in|sigfig=1|abbr=on}} long reaching to a height of {{convert|200-350|mm|in|sigfig=1|abbr=on}}. As with others in the genus, the flowers are inverted so that the labellum is above the column rather than below it. The dorsal sepal is egg-shaped to lance-shaped, {{convert|7-10|mm|in|sigfig=1|abbr=on}} long. The lateral sepals are a similar size and shape to the dorsal sepal and are sometimes joined to each other near their bases. The petals are linear in shape and about {{convert|6-8|mm|in|sigfig=1|abbr=on}} long. The labellum is reddish or white, {{convert|6-8|mm|in|sigfig=1|abbr=on}} long, turns upwards at about 90° and has slightly wavy edges. Flowering occurs from October to December.[1][2]Taxonomy and namingPrasophyllum barnettii was first formally described in 2006 by David Jones and Dean Rouse from a specimen collected near Anglesea and the description was published in Australian Orchid Research.[3] The specific epithet (barnettii) honours the Australian naturalist Paul Barnett (1927-1996).[2]Distribution and habitatThis leek orchid grows with grasses or shrubs in forest in the Otway Ranges and coastal areas between Anglesea and Princetown.[1] References1. ^1 {{cite web|last1=Jeanes|first1=Jeff|title=Prasophyllum barnettii|url=https://vicflora.rbg.vic.gov.au/flora/taxon/ae0ac6ba-ffb0-4621-ab55-e03206c2cf2f|publisher=Royal Botanic Gardens Victoria - vicflora|accessdate=1 November 2017}} 2. ^1 {{cite journal|last1=Jones|first1=David L.|title=New taxa of Australian Orchidaceae|journal=Australian Orchid Research|date=2006|volume=5|pages=145–146}} 3. ^1 {{cite web|title=Prasophyllum barnettii|url= https://id.biodiversity.org.au/instance/apni/616376 |publisher=APNI|accessdate=1 November 2017}} External links
