Population A single collection from 1910 is the only record of this species. It occurred in the Usambara Mts. but has not been found again despite extensive botanical work in the area.
Threats The forest has suffered from the encroachment of agriculture and commercial forestry.
Conservation Measures The forest is now the focus of a conservation programme.
