Pittosporum rubiginosum, commonly known as hairy red pittosporum, is an evergreen shrub in the family Pittosporaceae which is endemic to northeastern Queensland, Australia.
The hairy red pittosporum is a spindly shrub with a variable appearance as it grows. It usually reaches around 2–3 m (6 ft 7 in – 9 ft 10 in) in height, however it can (rarely) reach 6 m (20 ft).[4][5][6] The leaves are dark green above and usually purple underneath.[5][6] Both sides of the leaves are glabrescent, meaning that they are initially hairy but become hairless with age.[4][5] The size and shape of the leaves differ markedly from the juvenile stage to maturity − seedling leaves are densely hairy, those on a juvenile plant measure around 2.5 by 1.3 cm (0.98 by 0.51 in) while those of mature plants are about 24 by 8 cm (9.4 by 3.1 in).[4][5] All stages have very short petioles and are mucronate, that is, they have a fine sharp point at the tip of the leaf.[4][5]
The inflorescence is an umbel produced either terminally or in the leaf axils.[6] The fruit are yellow and split open to reveal a cluster of bright red seeds.
This species was first described in 1840 by the English botanist Allan Cunningham, in a footnote in his paper dealing with the flora of New Zealand.[7] The species Pittosporum callicarpeum, published in 1925 by the Czech botanist Karel Domin, is now considered a synonym of this species.[8]
The genus name Pittosporum comes from the Ancient Greek words πίττα (pítta) meaning "resin", and σπορά (sporā́), meaning "seed", and is a reference to the sticky seeds. The species epithet rubiginosum is derived from the Latin robiginosus, meaning "rusty red", which may be a reference to the colour of the seeds,[6] or to the colour of the hairs on new growth.[5]
This species is listed by the Queensland Department of Environment and Science as least concern.[1] As of 14 April 2023, it has not been assessed by the International Union for Conservation of Nature (IUCN).
