Phryma leptostachya (American lopseed)
Smith, R.W.

Phryma leptostachya

Phryma leptostachya L.

American Lopseed, Lopseed

Verbenaceae (Verbena Family)

Synonym(s): Phryma leptostachya var. confertifolia

USDA Symbol: PHLE5

USDA Native Status: L48 (N), CAN (N)

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.

This species is a member of the verbena family (family Verbenaceae), which includes about 75 genera and 3,000 species of herbs, shrubs, and trees, mostly of tropical and warm temperate regions. Among them, teak is a highly prized furniture wood, and Vervain, Lantana, Lippia or Frog Fruit, and Chase Tree or Vitex are grown as ornamentals.
