Pairs of small, white or pinkish-lavender flowers in slender, elongated, spike-like clusters along top of stem and its diverging branches. This species also occurs in Asia. The downward-hanging fruit, which accounts for the common name, makes the plant easily recognizable. Three of the calyx teeth are hooked at the tip, which may assist in dispersal by attachment to animals.

This species is sometimes placed in its own family, the Phrymaceae.
