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.
