The subpopulation on the Uluguru Mts has possibly gone, the subpopulations in the Livingstone Mts could be under threat from potato farming and accidental collecting along with orchid bulbs. It meets the area of occupancy requirements for listing under Vulnerable (likewise if the Uluguru subpopulation has gone then it would also qualify under the extent of occurrence thresholds), is known from fewer than ten locations and there appears to be continuing declines due to various threats. Hence is listed as Vulnerable.

Geographic Range [top]

Range Description:Has a disjunct record in the Uluguru Mts, all the other records are from further to the west at the north end of Lake Tannganyika (Livingstone Mountains). The subpopulation at the Ulugurus may be gone, it was outside of any protected area, and most of those grasslands have been converted to agriculture.
Countries occurrence:
Tanzania, United Republic of

Population [top]

Population:Was reported to be common at the type locality.
Current Population Trend:Decreasing
Additional data:
Continuing decline of mature individuals:Unknown
Extreme fluctuations:NoPopulation severely fragmented:No

Habitat and Ecology [top]

Habitat and Ecology:Grows in rocky montane grassland.
Continuing decline in area, extent and/or quality of habitat:Yes

Threats [top]

Major Threat(s): There is evidence of removal of orchid bulbs for sale in nearby Zambia, and the bulbs of this species may also be impacted at the same time. At the Uluguru Mtn location there has been extensive loss of habitat due to conversion to agricultural land. The Livingstone Mts area could also be impacted in future by increased conversion of grassland areas to agriculture (potato farming).

Conservation Actions [top]

Conservation Actions: The species is well protected in the type locality - Kitulo National Park and is also known to occur in Chimala Scarp Forest Reserve.
