| Abstract: | Pollen tetrads within Amaryllidaceae are reported for the first time for Stenomesson elwesii. Tetrads were examined with light and scanning and transmission electron microscopy. The tetrads are tetragonal in shape. Tetrad-members are rounded-triangular in equatorial view and elliptic in polar view. Average polar diam is 50.1 μm; average longest equatorial diam is 62.5 μm. Morphology of the aperture is monosulcate. Exine sculpturing of the intectate pollen is gemmate. Systematic implications are briefly discussed. |
