Intrapetiolar

a.
  1. 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.
