Cattleya alaorii Cattleya alaorii Cattleya alaorii, commonly known as the Laelia alaorii, is a species of orchid endemic to Brazil (Bahia). The species was named after Mr. Alaor Oliveira, former employee at the University of São Paulo at Piracicaba, who first collected this species in a field excursion in the late 1960s. It was discovered in the 1970s in an isolated mountain chain near Itabuna, Bahia state. It grows in the very wet Bahia coastal forests ecoregion of the Atlantic Forest biome ("Mata Atlantica Brasileira"). It is found in rainforests at about above sea level. The plants are epiphytes in tall trees
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
