| The main culms of the plants were harvested at anthesis, 18 days post-anthesis and at maturity. |
| On each individual, three flowers were emasculated before anthesis and isolated using silk bags, while the fourth was taken as the pollen donor. |
| Anthers were isolated from flowers at anthesis and pollen grains were collected. |
| As the ovary elongates only above the placenta, the ovules appear basal at anthesis. |
| In developing flowers the stamens are tightly appressed but soon mature centripetally and bend extrorsely at anthesis. |
| Only the outermost two or three cell layers and the inner epidermis remain compact at anthesis. |
