verticil

The adhesion or cohesion of different floral verticils or sets of organs.

This suppression when confined to the parts of certain verticils makes the flower asymmetrical.

Stamens 12 in 4 verticils, 9 fertile and 3 inner sterile.

In panicles, especially when they are diffuse, the primary branches may be disposed irregularly or in verticils on the main axis.

So in Saponaria, in Dianthus, and other Caryophylleæ, three and four verticils of stamens have been met with.
