Vine Honeysuckle Lonicera spp.
Family: Caprifoliaceae (Honeysuckle)
Branching: Opposite

Several species of Honeysuckle are vines. Their bark and buds closely resemble the shrubby species. Lacking tendrils, they climb by winding their stems around their "host". Unlike the shrubby species, all have hollow branches (hollow branches are only found in non-native shrub Honeysuckles). All these pictures are from one particular plant. I'm not sure exactly what species it is, but it's likely either Rock or Mountain Honeysuckle (L. prolifera or L. dioica)

Vine Honeysuckles climb without tendrils.
