Prostanthera pedicellata is a species of flowering plant in the family Lamiaceae and is endemic to a restricted area of Western Australia. It is a small shrub with densely glandular branches, egg-shaped to oval leaves and red flowers.
Prostanthera pedicellata is a shrub that typically grows to a height of and has glabrous, densely glandular branches. The leaves are arranged along the branches and are narrow egg-shaped to oblong, long, wide and more or less sessile. Each flower is on a pedicel long with sepals forming a tube long with two lobes long. The petals are red, long and form a tube long. The lower lip of the petal tube has three lobes, the centre lobe egg-shaped, long and the side lobes about long. The upper lip is long, wide with a central notch up to deep. Flowering occurs from August to November.[1]
Prostanthera pedicellata was first formally described in 1984 by Barry Conn in the Journal of the Adelaide Botanic Garden from specimens collected by Eric Ashby in 1969, near Pindar.[2] [3]
This mintbush grows on ironstone gravel on plains and is only known from near Pindar in the Avon Wheatbelt biogeographic region, where its population size is decreasing due to land clearing.
Prostanthera pedicellata is classified as "Priority One" by the Government of Western Australia Department of Parks and Wildlife, meaning that it is known from only one or a few locations which are potentially at risk.[4]
