Cattleya genus Cattleya are: Currently accepted natural hybrids are: 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
Flower constancy could require substantial investment and switching to other flower types or species could be inefficient and consequently non-adaptive. Concentrating and feeding on one particular flower type increases the insect’s efficiency to obtain nectar from that flower type with respect to other flower types that are available. The costly information hypothesis explains flower constancy based on the fact that insects stay constant and feed on a one flower type because they know they are obtaining a reliable reward: nectar. The insect therefore does not venture to feed on other flower types because it cannot predict the amount of nectar in other
