| Rhodolaena altivola | |
Rhodolaena altivola is a tree in the family Sarcolaenaceae. It is endemic to Madagascar. The naturalist and explorer Alfred Russel Wallace described it as "among the most magnificent flowering plants in the world".[3]
Description
Rhodolaena altivola grows as a small to medium-sized tree. It has medium, ovate leaves. The inflorescences have one or two flowers on a long stem. Individual flowers are very large with five sepals and five purple-red petals, measuring up 5 cm (2 in) long. The fruits are large and woody.[4]
Distribution and habitat
Rhodolaena altivola is only found in the eastern regions of Atsinanana and Analanjirofo.[2] Its habitat is humid to subhumid evergreen forests from 200 m (700 ft) to 1,000 m (3,300 ft) altitude.[4]
Threats
Rhodolaena altivola is threatened by shifting cultivation and wildfires. Its future population decline due to habitat loss is predicted at more than 80%. No population of the trees is currently in a protected area.[4] The status of the species is critically endangered.[1]
