Later this separated from those Cuba, identified as elliotri Engelm. Cuba retained caribaea. Subsequently, into three varieties: caribaea, bahamensis, hondurensis. hondurensis variety has been most widely introduced plantations tropical subtropical regions world; it grows vigorously various climates tropics fonns more than 80% world's listed under Unfortunately is associated with poor seed production outside its native range, all regeneration methods adopted grow have not fully satisfactory except for seed. Latitudinal displacement resulting large scale introduction natural primary cause range. recently successfully regenerated tissue culture, but genetic instability roots culture seedlings that induced high concentrations exogenous auxins rooting remains problem. In addition elevated nuclear DNA produced ontogenetically nDNA nuclei dormant embryos which upon germination migates cytoplasm metabolized. significance perpetuation possible relation are discussed.
