Cattleya crispa was sunk into the genus "Cattleya", and "S. crispa" was given its original name of "C. crispa". Cattleya crispa Cattleya crispa is a species of orchid indigenous to the Tijuca Mountains north of Rio de Janeiro, Brazil, noted for its crisped and ruffled petals and lip. It is the type species for both the subgenus "Cattleya" subg. "Crispae" and its section "Cattleya" sect. "Crispae". Prior to 2000, "C. crispa" had long been placed in the genus "Laelia" because it had eight pollinia, instead of the four found in "Cattleya labiata", the type species of the genus "Cattleya".

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
