Intrapetiolar \In`tra*pet"i*o*lar\, a. (Bot.)
   Situated between the petiole and the stem; -- said of the
   pair of stipules at the base of a petiole when united by
   those margins next the petiole, thus seeming to form a single
   stipule between the petiole and the stem or branch; -- often
   confounded with interpetiolar, from which it differs
   essentially in meaning.
