Cattleya walkeriana Cattleya walkeriana Cattleya walkeriana (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. In its native habitat (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. Inflorescence is one- or few-flowered, about 8" (20 cm) tall. Flowers are 4-5" (9-12 cm) across. Genetically "C. walkeriana" is close to bifoliate Cattleyas. The diploid chromosome number of "C.
Cattleya labiata plant has a pseudobulb under every leaf to store water and nutritive substances during the short dry season. In the wet season new leaves grow rapidly, producing a large flowered inflorescence. Flowers are white or lavender colored with a darker spot in the lip. Pollination is performed by insects, usually by a scent-collecting male euglossine bee. The result is a capsule with a very large number of seeds (10,000-20,000). The diploid chromosome number of "C. labiata" has been variously determined as 2"n" = 40, 41, and 46. The haploid chromosome number of "C. labiata" has been variously determined as "n"
