Lonicera subspicata

Lonicera subspicata is a species of honeysuckle known by the common name southern honeysuckle. It is native to Baja California, California, and northern Baja California Sur, where it is known from several areas in mountain and coastal habitat, particularly chaparral. It is a vining shrub which usually climbs on other plants for support.

The leaves are generally 1 to 4 cm long, with the base of the leaf blade round or more or less tapered, and the tip of the leaf shaped round or obtuse. Upper pairs are not fused around the stem.
