'''''Justicia''''' is a genus of about 420 species of [[flowering plant]]s in the family [[Acanthaceae]], native to tropical to warm temperate regions of the [[Americas]], with two species occurring north into cooler temperate regions. Common names include '''water-willow''' and '''shrimp plant''', the latter from the [[inflorescence]]s, which resemble a [[shrimp]] in some species.

Line 16: Line 22:  
Of the justicias appearing in American lists, only J. furcata, Jacq. (Adhatoda furcata, DC.) seems now to be retained in the genus. Herbaceous, pubescent, the st. erect and terete: lvs. oblong-oval, attenuate to petiole: fls. small, in short aggregated axillary spikes which are often geminate, the bracts linear-lanceolate; color of fls. purple and white; upper lip 2-fid, the lower 3-fid and broad-convex. S. Mex.—Said to seed itself freely in S. Calif., but to be of little value.
