Are Cattleya and Leucocoryne of the same genus of flowers?
Cattleya Cattleya is a genus of orchids from Costa Rica south to Argentina. The genus is abbreviated C in trade journals.
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.
