Cattleya walkeriana (Walker's cattleya) is a species of orchid that differs from most species of Cattleya by having inflorescences which arise from the rhizome instead of from the apex of the pseudobulb.
In its native habitat of the Brazilian Central Plateau it grows as either an epiphyte or a lithophyte, sometimes in full sun.
Pseudobulbs are relatively short, bulbous or fusiform, with one or two ovate leaves at the apex.
The inflorescence is one or few-flowered and about 20 cm tall and the flowers are around 9-12 cm across.
