  "definition": "Japanese hop, or hops, is an herbaceous, usually annual vine that lacks tendrils and climbs by twining. It is shallow-rooted but can climb to heights of ten feet or more with the help of rough-textured stems that are covered with short, sharp, downward pointing prickles. These prickles can be very irritating to the skin. The leaves are rough textured, paired, and palmate with 5 to 7 (sometimes 9) lobes. The margins of the leaves are toothed. The leaf stems (petioles) tend to be as long as or longer than the leaves and have a pair of small bracts at the base. Male and female flowers are borne on separate plants. The male flowers are very small, greenish yellow and occur in branched panicles. The female flowers are in pale green, plump, drooping, cone-like structures with overlapping scales called hops. The hop scales and the seeds are covered with yellow glands. The seeds are about 1/8 in. in diameter, roundish with a blunt tip, and light brown with darker specks.",
