quarter-vine

Century Dictionary and Cyclopedia

1. n. An American vine, Bignonia capreolata. It is so called because, owing to the projection of medullary tissue in four wing-like layers from the middle to near the surface, a short section of the stem, when gently twisted in the hand, will divide into quarters. See cross-vine.
