The cotyledons and corolla of a plant are worked on by an expansive force, while the calyx and coronas are affected by a contractive force.
Some seeds are starchy, and some have resiny calyx tubes while others have thick ones.
Uninfested fruits were not entered by females except in the case of apple where they entered through the calyx.
The calyx was excluded from this measurement as preliminary experiments indicated that very few of the insects attempted to feed on this structure.
Most species are easily distinguished by their highly attractive, double inflorescences and imbricate calyx-lobes.
Veronica species were described as smooth/hairy because all seeds observed attached to the dog were enclosed in the hairy calyx.
There are five petals which are deeply notched at the end, narrowed at the base and all go into an urn-shaped calyx.
The calyx of the flower is usually 1 centimeter long and very hairy, with 3 lobes that may appear to be triangular or obtuse.
