Cattleya warscewiczii Cattleya warscewiczii Cattleya warscewiczii (The "Warscewicz's Cattley's orchid"), a labiate "Cattleya", is a species of orchid. It was first collected by Józef Warszewicz in Colombia in 1848-49 and formally described by Heinrich Gustav Reichenbach in 1855. "C. warscewiczii" exhibits a typical Cattleya sympodial habit. Pseudobulbs are 8-16" (20-40 cm) long, unifoliate, cylindrical or cigar-shaped, grooved. Flowers are 7-11" (17.5-27.5 cm) across, largest in the genus, showy, fragrant. In culture the flowering is in summer on that year`s spring growth. Strong light and good air movement are required. The diploid chromosome number of "C. warscewiczii" has been determined as 2"n" =
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
