Prasophyllum elatum R.Br., Prodr. Fl. Nov. Holl. 318 1810. (Syn: Prasophyllum australe Lindl.); Flora-Australia-42: Prasophyllum elatum- ground orchid from bush I imagine why it is called Swamp Leek Orchid!! Those shiny things on the labellum must be attracting insects for pollination. How was the fragrance? Refrences: http://www.theplantlist.org/tpl/record/kew-164707
