État de la populationTexte officiel évaluation IUCNExpert
The main population consists of about 35 mature plants in a stream bordering the Kalugala Forest Reserve and not within the protected area (Madola et al. 2021). Few individuals (about three mature individuals) have been recorded in the stream within the protected area. There are reports of people collecting large numbers of plants for export. According to personal communication with the villagers, a few years back there had been a person who visited the area regularly and collected plants on a large scale with the help of the villagers for export.
