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.
Flower constancy (LTM) or "reference memory", which stores information for hours or more. One of the most widespread explanations for flower constancy is that insects can only identify and handle one flower type or species at a time. Conversely, there are others that argue that insects, for example bees, can store large amounts of information (location of nest, flower patches, and existence of surrounding landmarks) in their LTM or reference memory. The learning investment hypothesis refers to the ability of an insect to learn a motor skill to handle and obtain nectar from a flower type or species. Learning these motor skills
