verticillate (adv.), verticillatim (adv.): verticillately, in a whorled manner.

verticillatus,-a,-um (adj.A): verticillate, whorled; “when several bodies form a ring round a common axis, as leaves round a stem, sepals, petals, and stamens round an ovarium, &c.” (Lindley); (in bryology) whorled (Magill 1990);

- univerticillatus, biverticillatus, triverticillatus, once, twice, thrice verticillate.

Rumex verticillatus L. 'whorled', the whorls of flowers distant to subapproximate on the rhachis.

NOTE: monoverticillatus,-a,-um (adj.A): this word occurs in English as a Greek and Latin hybrid word meaning 'with a single whorl,' as in a seashell; in Latin it is univerticillatus.
