Cattleya Cattleya Cattleya () is a genus of orchids from Costa Rica south to Argentina. The genus is abbreviated C in trade journals. Epiphytic or terrestrial orchids with cylindrical rhizome from which the fleshy noodle-like roots grow. Pseudobulbs can be conical, spindle-shaped or cylindrical; with upright growth; one or two leaves growing from the top of them. The leaves can be oblong, lanceolate or elliptical, somewhat fleshy, with smooth margin. The inflorescence is a terminal raceme with few or several flowers. Flowers have sepals and petals free from each other; the lip or labellum (lowermost petal), usually has a different coloration
Flower constancy more dissimilar, for example in their coloration. When, in a community of flowering plants, the flowers are all similarly colored, the constancy is often lower because different species are more difficult to distinguish, whereas constancy tends to be higher when the flowers are distinctly differently colored. Flower constancy benefits flower pollination but, arguably, constancy is not so obviously adaptive for pollinators. Individuals that show constant behavior ignore other flowers that could potentially provide more nectar (reward) than their preferred type. As a result, flower constancy seems to contradict optimal foraging models, which assume that animals will move minimal distances between
