Erica arborea
In the alpine zone of Mount Kenya, "Dendrosenecio keniodendron" is the dominant woody species, forming evenly sized and evenly aged dense stands with nearly closed canopies. The taller stands tend to support a community of the shrubs from the genus "Alchemilla": "Alchemilla argyrophylla" and "Alchemilla johnstonii" and shorter stands supporting grasses from the genus "Festuca" and "Carex": "Festuca pilgeri" and "Carex monostachya" which resemble each other and have perhaps been often misidentified. Also found in these communities are the species pairs: from "Poa": "Poa schimperi" and "Poa leptoclada", "Cerastium": "Cerastium octandrum" and "Cerastium afromontanum", and the pair of "Ericas": "Erica timera" and "Erica arborea".
