Easily mistaken for : Wilson's Honeysuckle (Lonicera nitida) because both have a similar jizz and purple berries but Wilson's Honeysuckle has shorter leaves ([4] 6-16mm as opposed to [6] 12-32mm of Box-leaved Honeysuckle) and similar but slightly shorter conically-tubular actinomorphic/hemi-zygomorphic flowers (5-7mm as opposed to 6-8mm of Box-leaved Honeysuckle) . The berries are similarly coloured translucent purple and are roughly the same size for both plants, 6mm. Although Box-leaved Honeysuckle grows to only about half the height (1m) as does Wilson's Honeysuckle (1.8m), the leaves and flowers of the latter are larger than that of the shorter Box-leaved Honeysuckle plant.

As a by-word, Wilson's Honeysuckle (Lonicera nitida) has a slight resemblance (when not in flower) to Wall Cotoneasters (Cotoneaster horizontalis) on account of the herringbone pattern of the branched branches, although in the case of Box-leaved Honeysuckle, the branches are not all parallel to each other and diverge somewhat. The leaves of Wall Cotoneaster are also a similar shape to those of Wilson's Honeysuckle but alternate rather than in opposite pairs.

Not directly related to : Himalayan Honeysuckle [which is in the same Honeysuckle Family but in a differing genus, Leycestaria].

No relation to : Box (Buxus sempervirens) [a plant with similar name belonging to a differing family], but has leaves like that of Box.

An evergreen and broadleaf non-native garden shrub native to Central & SW China which escapes as bird-sown occasionally. It is widely planted as a roadside border shrub by Municipal Councils. It has a large translucent and purple berry in which the seeds can be discerned.
