Cattleya amethystoglossa Cattleya amethystoglossa Cattleya amethystoglossa (the "amethyst-lipped Cattley flower") is a bifoliate species of orchid from the genus "Cattleya". "C. amethystoglossa" is native to Brazil in the states of Bahia and possibly Espirito Santo, where it is found near sea level in close proximity to the Atlantic Ocean. "C. amethystoglossa" grows on palm tree trunks, rock, and large tree branches high in the canopy of evergreen trees. This plant is found growing in bright, airy, humid locations. Its native range has been greatly reduced due to habitat destruction, logging, and agriculture. "C. amethystoglossa" is a tall plant and has pseudobulbs that
Basics of blue flower colouration of co-pigmentation, intermolecular and intramolecular. In the first type co-pigment is bound to anthocyanin by non-covalent bond (hydrogen bond, hydrophobic interaction, ionic interaction). In the second type, we can observe covalent acylation of the glycosyl moiety of anthocyanin. Intramolecular co-pigmentation has stronger effect on the colour. This type of protective stacking is called also a sandwich type stacking and is a very common mechanism in the formation of blue flower colour. Tirantin present in "Clitoria ternatea" (butterfly pea) and phacelianin present in "Phacelia campanularia" are examples of pigments with intramolecular co-pigmentation.
