Overall appears to have a small area of occupancy (less than 500 km²), known from five locations and there are continuing declines because of threats to the habitats. In all places the population sizes are small. Might also qualify under criterion C, but there is not enough information from all the subpopulations to apply that criterion.
|Previously published Red List assessments:||
|Range Description:||Recorded in the Taita Hills and at Nairobi River Falls (Kenya) and the South Pare Mts, Manyara escarpment, Ngubora River and Lake Eyassi (Tanzania).
Note that the distribution recorded in Reynolds (1966) as at the top of the Manyara Escarpment and Nguruman Escarpment refers to Aloe elata S.Carter & L.E.Newton.

|Population:||Never very common, all subpopulations tend to be small.|
|Current Population Trend:||Decreasing|
|Habitat and Ecology:||Grows in dry deciduous bushland with Acacia and succulents and also in degraded bush on rocky hills.|
|Continuing decline in area, extent and/or quality of habitat:||Yes|
|Use and Trade:||
Is grown by succulent collectors and botanic gardens.
The sap of the species contains poisonous hemlock alkaloids (Carter 1994).
|Major Threat(s):||This dry bushland is extensively exploited for charcoal production and also by habitat clearance for exapnding agriculture.|
|Conservation Actions:||Occurs in at least two protected areas: one locality near Kwizu Forest Reserve and in Mkomazi Game Reserve (a sight record).|
