It is abundant, common and secure on old lava flows on Mt Cameroon, but elsewhere it appears rare and precarious (see threats below). Seven sites are known.

|Current Population Trend:||Decreasing|
|Habitat and Ecology:||Occurs in grassland, near forest, often at well-drained sites; (1,000–)2,000 m alt.|
|Major Threat(s):||Threats are poorly known, but grazing and the associated annual firing of grassland are considered likely to be detrimental to this species. In addition, cultivation of habitat for crops e.g., at Lake Aweng, Santa and Bamboutos, is a threat.|
|Conservation Actions:||The effect of forest loss on this, and other rare, sun-loving Compositae, many of which share the same range of habitats, is poorly understood. Research is needed to redress this. Limited 'habitat destruction' at intervals of years, in the form of fires or limited long-fallow small-holder agriculture or small scale tree felling may be helpful to the survival of such taxa by keeping their habitat open and allowing establishment of probably short-lived perennials such as these.|
