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". In 2000, the
Flowering plant is the pairing of homologous chromosomes and homologous recombination (the exchange of genetic information) between homologous chromosomes. This process promotes the production of increased genetic diversity among progeny and the recombinational repair of damages in the DNA to be passed on to progeny. To explain the adaptive function of meiosis in flowering plants, some authors emphasize diversity and others emphasize DNA repair. Apomixis (reproduction via asexually formed seeds) is found naturally in about 2.2% of angiosperm genera. One type of apomixis, gametophytic apomixis found in a dandelion species involves formation of an unreduced embryo sac due to incomplete meiosis (apomeiosis)
