Cattleya fournieri

A small rupicolous Cattleya (formerly Laelia fournieri) from the rocky highland outcrops of Minas Gerais, Brazil, with short, clustered pseudobulbs, one thick leaf and pale yellow to cream flowers on a tall stem. It grows on rocks in open, sunny campo rupestre, with a wet summer and a long, cool, very dry winter. Measured climate from 53 wild records supports cool nights and a strong dry season.

Where it grows wild

A lithophyte of the rupicolous 'Parviflorae' group, growing on rock outcrops and among grasses and shrubs in the open highland vegetation (campo rupestre) of central Minas Gerais. It is exposed to near full sun and strong wind.

Recorded elevations are 1,217–1,699 m (median 1,500 m); Wikipedia gives 1,100–1,800 m. The altitude explains the mild days and cool winter nights.
