Caprifoil

Sunny, shrubby banks are fairly crowded with caprifoils, so easily known by their opposite leaves, monopeta lous more or less irregular flowers with the parts in fives, save style, and ovary blended with walls of the calyx-tube.

...and if we descend to the criterion of stipular line, as is done to evidence the genuineness of some Rubiaceae, we need exclude no caprifoils except those of the genus Alseuosmia which have alternate leaves.

In some respects they are near caprifoils, from which they are readily known, not only by their parasitical habit, but also by their stamens being opposite valvate lobes of a tubular calyx.
