What is a connective?
The connective is part of a stamen.
Where the connective is very small, or imperceptible, the anther lobes are close together, and the connective is referred to as discrete, e.g. Euphorbia pp., Adhatoda zeylanica. Where the connective separates the anther lobes, it is called divaricate, e.g. Tilia, Justicia gendarussa. The connective may also be a long and stalk-like, crosswise on the filament, this is a distractile connective, e.g. Salvia. The connective may also bear appendages, and is called appendiculate, e.g. Nerium odorum and some other species of Apocynaceae. In Nerium, the appendages are united as a staminal corona.
