The caper-berry (κάππαρις) shall fail, i.e. no longer stimulate appetite.  But διασχεδασθήσεται (Sept. Cyril) means that the old man shall be like a caper-berry which when fully ripe bursts it husks and scatters its seeds:  so R.V. (Margin); The caper-berry shall burst.  Greg. Thaumat. Metaphr. Eccles.  “The transgressors are cast out of the way, like a black and despicable caper-plant.”
