Cattleya walkeriana, or Walker's cattleya, is a species of orchid. It differs from most species of Cattleya by having inflorescences which arise from the rhizome instead of from the apex of the pseudobulb [nb 1] . In its native habitat (the Brazilian Central Plateau) it grows as either an epiphyte or a lithophyte, sometimes in full sun, at elevations up to 2000 meters [1] [nb 2] . Pseudobulbs are relatively short, bulbous or fusiform, with one or two ovate leaves at the apex. Inflorescence is one- or few-flowered, about 8" (20 cm) tall. Flowers are 4-5" (9-12 cm) across. [2] [3]

Contents

Genetically, C. walkeriana is close to bifoliate Cattleyas. [4] The diploid chromosome number of C. walkeriana has been twice determined as 2n = 40; the diploid chromosome number of the variety C. walkeriana var. princeps L.C.Menzes has been determined as 2n = 80. [5]

Notes

  1. ↑ The only other Cattleya species that exhibits this trait is C. nobilior .
  2. ↑ In culture some protection from direct sun is needed, as plants not habituated to full sun will readily sunburn.
