Woody vine climbing to top of Celtis occidentalis tree 40 cm. in diameter and 55 years old.
Stem 4 cm. in diameter, with thick bark, the wood cylinder 2.5 cm. in diameter, the large vessels forming nearly adjacent rings which may be annual rings and then this vine perhaps about as old as the support tree, the bare stem hanging free for the lower 11 m. above the ground, then beginning to produce short (< 1 m. long) flowering side shoots but without any adventituous roots or tendrils. At 14 m. the tree begins to branch and the vine begins being irregularly entwined in the branches, rarely with tendrils with sticky pads toward the top of the tree but these not effective in climbing. Voucher ofr wood specimens at Kw, Lw, MADw, MEXUw, RSAw. Topmost leaves completely skeletonized by japanese beetles (Popillia japonica), those in the shade and interior of canopy not much attacked.
