\Dex*tror"sal\, Dextrorse \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-gl['o]ry.
Note: 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.
