Abstract
A population of a narrow-range endemic Prasophyllum (Orchidaceae) that is similar to, but consistently different from, Prasophyllum keltonii D.L.Jones is described here as the new species Prasophyllum laticallosum G.P.Phillips & H.C.Zimmer. This new species occurs within Kosciuszko National Park and is separated from Prasophyllum keltonii D.L.Jones by approximately 20 km, but is morphologically distinct. Feral herbivores (including feral horses) threaten this species and its habitat.
