This species is listed as Near Threatened given its relatively small area of occupancy and the doubt over the continued presence of this species in São Tomé and the conversion of some habitats in Tanzania for agriculture.
Previously published Red List assessments:

Geographic Range [top]

Range Description:Found in the Usambara, Ngurus, Udzungwa and Uluguru Mountains, Tanzania and the island of São Tomé.  Last collected in 2008.  The bulk of the population is found in areas on the eastern Tanzanian mountains. Another subpopulation, which shows some morphological distinctness and was originally published under the name of M. henriquesii, occurs on the island of São Tomé.  There have been no records of Sao Tomé specimen despite rigorous surveys of the island. If it still occurs here, the population is likely small, and found in areas which were forest at the turn of the century but are now cultivated or secondary forest. 
Countries occurrence:
Sao Tomé and Principe (Sâo Tomé); Tanzania, United Republic of

Threats [top]

Major Threat(s): This species is found in a number of forest reserves that are currently in good condition.  In one locality in Tanzania, there has been forest clearance for cardamom cultivation that would effect a shrub/tree of this size.  There is also encroachment on the forest by agriculture in Nguru South Forest Reserve.
