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.

Basics of blue flower colouration Basics of blue flower colouration Blue flower colour was always associated with something unusual and desired. Blue roses especially were assumed to be a dream that cannot be realised. Blue colour in flower petals is caused by anthocyanins, which are members of flavonoid class metabolites. We can diversify three main classes of anthocyanin pigments: cyaniding type (two hydroxyl groups in the B-ring) responsible for red coloration, pelargonidin type (one hydroxyl group in the B-ring) responsible for orange colour and delphinidin type (three hydroxyl groups in the B-ring) responsible for violet/blue flower and fruits coloration. The main difference in the structure
