Rhodolaena humblotii is a plant in the family Sarcolaenaceae. It is endemic to Madagascar.

Description

Rhodolaena humblotii grows as a shrub or small to medium-sized tree. The twigs have dense hairs. Its leaves are small and elliptic in shape. The inflorescences bear two flowers on a short peduncle. Individual flowers are large with five sepals and five pink-red petals, measuring up 5 centimetres (2 in) long. The fruits are medium-sized and woody.[3]

Distribution and habitat

Rhodolaena humblotii is only found in the eastern regions of Vatovavy-Fitovinany, Alaotra-Mangoro, Analanjirofo and Atsinanana.[2] Its habitat is evergreen and humid forests from 20 metres (100 ft) to 1,200 m (4,000 ft) altitude.[3]

Threats

Rhodolaena humblotii is threatened by timber exploitation. The timber is used in construction. Future population decline of the tree due to habitat loss is predicted at 50% to 80%, though subpopulations in protected areas are considered stable.[1][3]
