Cattleya aclandiae Cattleya aclandiae Cattleya aclandiae ("Lady Ackland's cattleya") is a species of orchid from the genus "Cattleya", named in honor of Lady Lydia Elizabeth Ackland, wife of Sir Thomas Dyke Acland, 10th Baronet who was the first European to grow the plant successfully. The illustration of the plant which accompanied its first description was based on a drawing by Lady Ackland. The genus was named in honour of William Cattley, a prominent British merchant and horticulturist. "Cattleya aclandiae" is found growing on tree limbs and trunks in the Brazilian state of Bahia. It has a very small natural range and is
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.
