Variable Chromosome Number and Ploidy Level of Five <i>Phyllanthus</i> Species in Bangladesh

Medicinally important five Phyllanthus species viz. P. acidus (L.) Skeels, emblica L. (small fruit form), (large niruri L., reticulatus Poir. and urinaria were cytogenetically studied through orcein-staining for authentic characterization. This genus showed variation in somatic chromosome numbers such as 2n=2x=26 (x=13) acidus, reticulatus, 2n=6x=48 (x=8) 2n=10x=100 (x=10) (both small large forms), represented with multi-basic number. Formation of bivalents addition to several multivalents at metaphase-I forms) indicated that this has the possibility being auto-allopolyploid or segmental-allopolyploid are going process diplodization.
