DECUMÀRIA Deeumaria barbara L, Not ¡Mus*

The pith of all vine honeysuckles is hollow (lacking). he twig bases are marked by persistent scales where they join the older branchlets. The opposing leaf scars are connected by lines and the bark is papery. The tubular flowers of all species except the Trumpet Honeysuckle have a single lower and 4 upper lobes at the mouth of the tube
