Description

Rhodolaena acutifolia grows as a small tree or shrub. [3] Its leaves are small, subcoriaceous, elliptic in shape, tapering to a point and sharp at the base. They measure up to 3 centimetres (1.2 in) wide. [4] The flowers are paired in solitary inflorescences on a long stem. [3] [4] Individual flowers are very large with bright purple-pink petals, measuring up 5 cm (2 in) long. [3] The fruits are dark green, drying black. [4]

Distribution and habitat

Rhodolaena acutifolia is only found in the east central regions of Analamanga, Alaotra-Mangoro and Analanjirofo. [2] Its habitat is humid evergreen forests from 350 m (1,000 ft) to 800 m (2,600 ft) altitude. Two subpopulations of the trees are in Zahamena National Park. [3]

Threats

Rhodolaena acutifolia is threatened by harvesting for timber. Due to shifting cultivation, future habitat loss is predicted at up to 50%. [3]
