Cattleya 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". In 2000, the "Brazilian "Laelias"" (including "L. crispa") were transferred to the genus "Sophronitis". In 2008, the entire genus "Sophronitis"
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.
