| The width of sepal should be measured as the width of the broadest of the sepals. |
| All observations on the color of the sepal, the petal and the lip should be made on the inner side. |
| Pistillate flowers are polymorphic for dehiscence and sepal number. |
| Lesions on flowers resemble those on the leaves. A single lesion on the pedicel or a sepal can make the flower desiccate and fall. |
| The upper sepal of each flower usually has a spur and stands upright, forming a hood. |
| Activity was also detected in the stigma, receptacle, and petal and sepal veins, and in siliques and developing seeds. |
