B. Herbaceous Twiners Hop, Ilumulus Lupulus*

Produces the hops of commerce, but should be in common use as an ornamental plant.

Chinese Yam, Cinnamon Vine, Dioscorea Divaricata (D. Batatas)

Climbs high, but does not produce as much foliage as some other vines.

A weed where it grows wild, but an excellent vine for some purposes.

Wild Morning-Glory, Rutland Beauty, Convolvulus Sepium* And California Rose, C. Japonicus

Japanese Ivy, Boston Ivy, A. Tricuspidata (A. Veitchii)

Handsomer than the Virginia creeper, and clings closer, but is often injured by winter in exposed, places, especially when young; in northern regions, tops should be protected for first year or two.
