It has a single tubular, bright green leaf and up to twenty five green, white and purplish flowers crowded on the flowering stem. It grows in montane swamps near Cathcart. DescriptionPrasophyllum caricetum is a terrestrial, perennial, deciduous, herb with an underground tuber and a single tube-shaped leaf, shiny, bright green leaf {{convert|200-350|mm|in|sigfig=2|abbr=on}} long with a whitish base. Between five and twenty five flowers are crowded along the flowering spike. The flowers are green with purplish and white petals and a white labellum. 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|7.5-12|mm|in|sigfig=1|abbr=on}} long, about {{convert|4|mm|in|sigfig=1|abbr=on}} wide and curves upwards. The lateral sepals are linear to lance-shaped, {{convert|7.5-12|mm|in|sigfig=1|abbr=on}} long, about {{convert|4|mm|in|sigfig=1|abbr=on}} wide and sometimes joined together. The petals are linear in shape and about the same dimensions as the lateral sepals. The labellum is broadly oblong or elliptic to egg-shaped, {{convert|8-14|mm|in|sigfig=1|abbr=on}} long, {{convert|4-6|mm|in|sigfig=2|abbr=on}} wide, turns upwards and has a wavy edge. Flowering occurs from December to February.[1]Taxonomy and namingPrasophyllum caricetum was first formally described in 2000 by David Jones from a specimen collected near Cathcart and the description was published in The Orchadian.[2]Distribution and habitatThis leek orchid grows in swamps with sedges and rush-like members of the family Restionaceae between Cathcart and Majors Creek.
