A tuberous canopy epiphyte with dramatic red and yellow flowers, this species is conspicuous near the summit of Mt. Etinde in the wet season, when in flower. No other Cameroonian species is known to have a tuber. Described in 1999 (Cheek and Fischer 1999), I. etindensis was previously named as Impatiens sp. nov. 2 aff. grandisepala and assessed as Vulnerable D2 in Cheek and Cable (1998: xlv, 21). The assessment here of I. etindensis as Endangered is taken from Cheek and Fischer (1999) and is maintained here since no new data are available. This species has an extent of occurrence of 33 km², an area of occupancy of 12 km², is known from two locations and there is continuing decline due to agricultural activities. Further work might prove the two locations contiguous, in which case a Critically Endangered listing would be appropriate.

Population size is not known but is thought to be in decline.

Current Population Trend:Decreasing
Additional data:
Population severely fragmented:No

Habitat and Ecology [top]

Habitat and Ecology:An epiphyte growing in submontane evergreen forest; (450-) 1,600-1,720 m alt.
Continuing decline in area, extent and/or quality of habitat:Yes

Threats [top]

Major Threat(s): The forest above Njonji is threatened by expansion of oil palm plantations.

Conservation Actions [top]

Conservation Actions: Monitoring of the plants in the summit area of Mt. Etinde is advisable. Protection of forest above Njonji should be considered if the site for this species is to survive. Cultivation at Limbe Botanic Garden is likely to prove difficult due to the altitudinal disparity.
