Pilidiostigma sessile is a species of plant in the clove and eucalyptus family Myrtaceae which is endemic to the Wet Tropics bioregion of Queensland, Australia.
Description
It is a much-branched shrub growing to about 5 m (16 ft) tall, with pale grey bark on the main stem. The leaves are dull green and measure up to 15 cm (6 in) long and 5 cm (2 in) wide. They are attached to the twigs either directly (sessile) or on a very short petiole about 1.5 mm (0.06 in) long. They have conspicuous lateral veins and two intramarginal veins.[4]
Flowers are small and occur either singly or on a short raceme about 15 mm (0.6 in) long. They have four petals and sepals, up to 4 mm (0.16 in) and 5 mm (0.20 in) long respectively. The petals are pink to purple. There are about 40 stamens and a single style (botany).[4]
The fruit is about 12 mm (0.5 in) long and 6 mm (0.2 in) wide, and contains a single seed.[4]
Taxonomy
Specimens of this species have been collected since 1972, but it was not until 2004 that botanist Neil Snow formally described and named it.[4][2]
Distribution and habitat
It is restricted to the Mount Lewis and Atherton Tableland areas, at altitudes from 1,100 to 1,300 m (3,600 to 4,300 ft). It grows in rainforest and has a preference for granite substrates.[4]
Conservation status
The species is listed as least concern under the Queensland Government's Nature Conservation Act.[1] As of 29 June 2026, it has not been assessed by the International Union for Conservation of Nature.
