Reproductive gametophytes fromtwo morphotypes were separated by morphology, sexuality andcharacteristic pattern distribution of reproductive cells: P. columbina (monoecious interspersed male and female patches distribution) and P. columbina f. 1 (dioecious and monoecious sectorised male and female patches distribution).The results of P. columbina (n=20 gametophytes) showed a basic haploid chromosome number of n=3, except one frond with 2 and 3 chromosomes in their cells. The results of P.columbina f.1 (n= 26 gametophytes) showed a haploid chromosome number of n=4, but the haploid condition wasfound inconsistently in some fronds, having a chromosome range from 3 to 5. Mean of nuclear DNA fluorescence ofspermatangia and zygotosporangia of both morphotypes had coherent haploid and diploid values.
