Ecology: Páramo and puna; exposed on rocks. Elevation: 2950-5000 m (Venezuela: 3850-4070 m, Colombia: 3200-4520 m, Ecuador: 2950-4500 m, Peru: 3350-5000 m, Bolivia: 3400-4930). Distribution: Widespread, in the tropics at high elevations.
The name Andreaea rupestris has been widely employed throughout the Andes and elsewhere, however a thorough study is needed to delineate the morphology of this taxon. Andreaea brevipes Spruce (type from Ecuador), recorded for Bolivia, is allied to A. rupestris; A. brevipes may be distinguished by the oblanceolate leaves that are wider above midleaf, and A. rupestris by the ovate- to oblong-lanceolate leaves, wider below midleaf. Differences howevery may only be a part of a broadly defined A. rupestris.
