Connation (Wikipedia)

Connation in plants is the developmental fusion of organs of the same type, for example, petals to one another to form a tubular corolla. This is in contrast to adnation, the fusion of dissimilar organs. Such organs are described as connate or adnate, respectively. When like organs that are usually well separated are placed next to each other, but not actually connected, they are described as connivent (that is the case for anthers in several genera, such as Solanum).

flower in the center of which is a projecting tube formed of the fused filaments of the stamens; the free anthers form a spreading cluster at its tip
The stamens of Hibiscus (like many Malvaceae) are synfilamentous.
