  Dextrorsal \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.] (Botany)
     Turning from the left to the right, in the ascending line, as
     in the spiral inclination of the stem of the common


     morning-glory; as, dextrorse vines.
     [1913 Webster]
  
     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.
           [1913 Webster]
