Dex*tror"sal (?), Dex"trorse` (?), a. [L. dextrorsum, contr. fr. dextrovorsum, dextroversum, toward the right side; dexter right + versus, vorsus, p. p. of vertere, vortere, to turn.]

Turning from the left to the right, in the ascending line, as in the spiral inclination of the stem of the common morning-glory.

⇒ At present scientists predicate dextrorse or sinistrorse quality of the plant regarded objectively; formerly the plant was regarded subjectively, and what is now called dextrorse was then considered sinistrorse.
