The shape is somewhat like honeysuckle, but the bracts of this species are narrow rather than leaflike, the calyx tube is densely pubescent, and the branchlets are densely curled pubescent, which is obviously different from this species. The morphological variation of this species is great, no matter in the indumentum of branches and leaves, the shape and size of leaves, the length of corolla, the ratio of indumentum and lip to catheter, etc. However, all these changes seem to be more related to the ecological environment than to the geographical distribution.
