Cattleya amethystoglossa Cattleya amethystoglossa Cattleya amethystoglossa (the "amethyst-lipped Cattley flower") is a bifoliate species of orchid from the genus "Cattleya". "C. amethystoglossa" is native to Brazil in the states of Bahia and possibly Espirito Santo, where it is found near sea level in close proximity to the Atlantic Ocean. "C. amethystoglossa" grows on palm tree trunks, rock, and large tree branches high in the canopy of evergreen trees. This plant is found growing in bright, airy, humid locations. Its native range has been greatly reduced due to habitat destruction, logging, and agriculture. "C. amethystoglossa" is a tall plant and has pseudobulbs that
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)
