Leaf Shape: Perfoliate

Leaf surrounds stem directly attaching to it; stem appears to go through the center of leaf; there is no visual petiole other than the stem.

When similar parts fuse together, like the leaves of these Honeysuckles, those fused parts are referred to as being connate. The description of the honeysuckle fused leaves would be “connate-perfoliate.”
