Description complète des menacesTexte détaillé évaluation IUCNExpert
The species is known only from the type collection, discovered in 1892 and there are no details about its preferred habitat nor its locality on the herbarium sheet. The species was possibly rediscovered near São Nicolau (T. Stévart and collaborators pers. comm.). Unfortunately, a living plant collected by Stévart and his team died before producing flowers, thus making it difficult to confirm identification. The species has an inconspicuous habit and it is not known if it is still present on that island. São Nicolau is located in the north of São Tomé and remaining habitat in that part of the island is now experiencing significant threats from shifting agriculture, selective logging and wood cutting for small-scale subsistence.

Mesures de conservation recommandéesStratégies de conservation IUCNExpert
The species is known only from the type specimen without locality. It is therefore difficult to know if there is any conservation actions in place for the species. Moreover, the island is now experiencing significant threats from shifting agriculture, selective logging and wood cutting for small-scale subsistence.
