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"
Flowering plant The APG system of 1998, and the later 2003 and 2009 revisions, treat the flowering plants as a clade called angiosperms without a formal botanical name. However, a formal classification was published alongside the 2009 revision in which the flowering plants form the Subclass Magnoliidae. The internal classification of this group has undergone considerable revision. The Cronquist system, proposed by Arthur Cronquist in 1968 and published in its full form in 1981, is still widely used but is no longer believed to accurately reflect phylogeny. A consensus about how the flowering plants should be arranged has recently begun to emerge
