The chromosome number in the antheridial filament cells of Nitella axillaris was investigated and found to be 36, although some cells of the same antheridium had more or less than this number. A comparison was made between the chromosome number of Nitella axillaris and other Characeae plants, and the possible origin of the chromosome number 36 was suggested. Amitotic nuclear division by a process of gradual pulling apart of the nucleus into two parts was observed in the lateral, internodal and rhizoidal cells.
