1. The nuclear structure of pollen mother cells of Reineckiacarnea KUNTH., at the promeiotic phase resembles that of resting root-tip cells. At this stage the nucleus contains generally two, sometimes only one, and rarely three nucleoli. The formation of two nucleoli takes place at the promeiotic telophase. 2. At the leptnema stage two nucleoli are stained lighter, while threads deeper, and karyosomes appear. 3. At the stage of loosening knot there appears one large nucleolus which stains deeply. 4. At the pachynema stage the staining condition of the spireme and nucleolus shows a reverse correlation, i.e. we find either spireme deeply stained and nucleolus lightly stained or vice versâ. Sometimes, a small globule is attached to a large nucleolus. Spiremc is found to be connected with this globule. This condition reminds of the case of nucleolar budding reported by GATES and SELIM. 5. At the interkinesis a large nucleolus appears. 6. Chromosome number is counted to be 38 in root-tip cells and 19 (bivalents) in pollen mother cells. 7. The rate of germination of pollen grains fluctuates between 14% and 49%, 25% in the average. 8. Anomalies of the meiosis in pollen mother-cells could often be found.
