HOPS.
(Humulus lupulus L.)
“A land of hops and poppy-mingled fields.”
—Tennyson: Aylmer’s Field.
The hop plant is a creeping perennial with several stems or branches attaining a length of fifteen to twenty-five feet. It has numerous opposite three to five lobed, palmately veined, coarsely toothed leaves with long leaf stalks (petioles). Flowers unisexual, that is staminate and pistillate flowers separate, either on separate plants (dioecious) or upon different branches of the same plant (monoecious). Flowers insignificant in loose, drooping axillary panicles. Fruit a cone-like catkin usually designated a strobile.
The hop has been called the northern vine. It is found in a wild state throughout Europe, excepting the extreme north, and extends east to the Caucasus and through central Asia. It is a handsome plant and not infrequently used as an arbor plant. The lower or basal leaves are very large, gradually decreasing in size toward the apex. H. lupulus is the only representative of the genus.
