2c. var. pubescens E. Small

Stems relatively hairy at the nodes. Leaf blades tending to have fewer lobes, those of the larger leaves unlobed or more commonly 3(4)-lobed, all of the leaves with 3 main veins from the base, the undersurface densely pubescent along the veins and usually also between them, the midvein with mostly more than 100 hairs per cm, also moderately to densely glandular with stalked glands, the surface between the veins mostly with more than 25 glands per square cm. July–October.

Scattered nearly throughout the state but apparently absent from the Mississippi Lowlands Division and some western portions of the Ozarks (Nebraska to Arkansas east to Pennsylvania and North Carolina). Banks of streams and rivers, margins of lakes, bottomland forests, and moist ledges of bluffs; also fencerows, railroads, roadsides, and disturbed areas.

This is by far the most common variety of H. lupulus in the state. The mostly northern var. lupuloides E. Small occurs immediately to the north of Missouri and should be searched for in the northernmost counties. It differs from var. lupulus in being somewhat less densely pubescent on the leaf undersurface, with hairs usually absent between the veins and more than 20 but less than 100 per cm along the midvein. It also tends to have more of the leaves 3-lobed, including most of the smaller leaves, whereas in var. pubescens the smaller leaves generally are unlobed and some of the larger leaves also can be unlobed.
