État de la populationExpert
When the type collection was made, about 20 plants were observed, scattered over several hundred metres along a path running up a slope (Cheek and Jannerup 2015). There is no further information about population numbers or trends, but we suspect a decline due to the habitat disappearing. Cheek and Jannerup (2015) suggested a Critically Endangered listing under criterion B2ab(iii).

Description complète des menacesExpert

This species is only known from Mkungwe Forest Reserve, where intense pit-sawing occurs in the central, eastern and western areas of the forest, with a camp present for the pit-sawers. Bush fires occur yearly that damage the edge of the closed forest. Hunting also occurs (Lovett and Pócs 1993, Doggart et al. 2000). Any threats which result in decreases in canopy cover and dessication of the soil layer would impact this sensitive species.
