Humulus lupulus, Linn. Common Hop. Perennial herb shoots often grow 25-30 ft. long in the season: rough-hairy: lvs. ovate or orbicular-ovate in general outline, deeply" 3-lobed (sometimes 5-7-lobed), or the upper ones not lobed, margins strongly and uniformly dentate, petioles long: staminate fls. in panicles 2-6 in. long: hops (mature pistillate catkins) oblong or ovoid, loose and papery, straw-yellow, often 2 in. or more long, glandular and odoriferous.—Native along rivers and in thickets in the northern states and Canada, and southward in the Alleghanies and Rockies; occurs as far south as Fla. and Ariz. Much cult, for "hops," used in brewing, and extensively run wild from cult, plants. The hop makes an excellent arbor or screen plant. Var. aureus has yellow foliage. G.W. 10, p. 501. The hop grows readily from cuttings of the shoots, which spring from the crown; also by seeds, but the latter do not reproduce the particular varieties or strains. As a field crop, the hop is not a horticultural subject, and is not discussed here. See Cyclo. Amer. Agric., Vol. II, p. 380. The Rocky Mt. form, common in Colo, and New Mex., has been separated as var. neo-mexicanus, Nels. & Ckll., and it is in the trade: it has more deeply divided lvs. and more sharply acuminate bracts than the ordinary hop; If .-segms. from broad- lanceolate to nearly linear, acuminate, with resin particles on the lower surface.
