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 This phenomenon we can observe in the morning glory (Ipomoea tricolor) and Japanese blue morning glory (Ipomoea nil) petals. During the flower development we can observe change of the flower colour form purple to blue. Morning glory has just one delphinidin type anthocyanin and the composition of it does not change during the flower development, but change of the colour is caused by increase of pH in vacuole of coloured cells from 6.6 in buds to 7.7 in fully matured flowers. During the early stage of development acidic pH is maintained by proton pumps, on the latter stage K+/H+ exchanger
