Description

Perrierodendron quartzitorum grows as a shrub or small tree up to 6 metres (20 ft) tall. Its chartaceous to subcoriaceous leaves are obovate to elliptical in shape. They are coloured dark green above, pale green below and measure up to 4 cm (2 in) long. The inflorescences bear one to three flowers, each with five sepals and five white petals. The orange fruits are conical and measure up to 2.5 cm (1 in) long.[3]

Distribution and habitat

Perrierodendron quartzitorum is found only in a single location in the Itremo Massif in the central region of Amoron'i Mania. The estimated area of occupancy is 45 km2 (17 sq mi). Its habitat is rocky areas and woodlands at about 1,000–2,000 m (3,300–6,600 ft) altitude.[2]

Threats

Perrierodendron quartzitorum is threatened by nomadic animal grazing and seasonal uncontrolled wildfires. The species population is decreasing.[1] Formerly, there were subpopulations in Isalo and Zombitse-Vohibasia National Parks,[2] but, as of the IUCN species assessment in 2015, there are no longer any subpopulations in protected areas.[1]
