| The staminode in other Asteridae families is on the adaxial side and a corolla lobe is the abaxial perianth organ. |
|
| At base of each petal is one nectar-secreting staminode whose broad, blade-like tip is crowned by 9-25, ca. 3 mm long pin-headed hairs. |
|
| Apostasia and the Cypripedioideae have two stamens, the central one being sterile and reduced to a staminode. |
|
| Commonly the odd stamen is more or less reduced to a staminode or even lacking. |
|
| For Watson and Dallwitz, a staminode is a sterile stamen, or a modified structure identifiable as such, borne in the androecial region of the flower. |
