Abstract Several plants invade the cushions of Laretia acaulis in the high Andean communities of central Chile. Humus develops among the rosettes, and 42 different species settle on the cushions. Most of these species are also found outside the cushions. Semi-woody chamaephytes, hemicryptophytes and cryptophytes have a similar cover on both substrates, while the cover of woody chamaephytes and therophytes is smaller on the cushions. The diversity and cover of invading plants, which vary with altitude, result from interactions among the environmental conditions, cushion morphology and the surrounding vegetation.
