Polyosma hirsuta, commonly known as hairy polyosma, is a plant in the family Escalloniaceae which is endemic to northeastern Queensland, Australia. It is an evergreen small tree growing up to 10 m (33 ft) high. The leaves may be 6 to 14 cm (2.4 to 5.5 in) long and 2 to 5 cm (0.79 to 1.97 in) wide, often with toothed margins and each tooth exhibiting a short stiff spine. Most parts of the plant, including the twigs, leaves and fruit, are clothed in fine pale brown hairs.
The inflorescence is a raceme (an unbranched spike) produced in the leaf axils or at the ends of branches. The cream-coloured flowers are tubular, about 12 mm (0.47 in) long by 3 mm (0.12 in) wide. The fruit is a rounded or ovoid, dark purple or black berry containing a single seed. The fruit measures about 20 mm × 14 mm (0.79 in × 0.55 in) and the seed about 10 mm × 7 mm (0.39 in × 0.28 in).




Taxonomy


The hairy polyosma was first described in 1918 by the Australian botanist Cyril Tenison White, based on material collected by the Reverend Norman Michael, an enthusiastic collector of botanic specimens in Queensland. Michael found the plant in the vicinity of the Johnstone River. White's description was published in Botany Bulletin, a publication of the then Queensland Department of Agriculture.




= Etymology

=
The genus name Polyosma is compounded from the Ancient Greek word poly meaning "many", and the Latin word osma, meaning "odour" or "smell". The species epithet hirsuta is from the Latin hirsutus meaning "hairy".




Distribution and habitat


Polyosma hirsuta is restricted to a small part of northeastern Queensland, on the coast and adjacent highlands from near Cooktown in the north to about Tully in the south. It grows as an understory tree in rainforest, at altitudes from near sea level to around 1,300 m (4,300 ft).
