Stems reddish, sometimes green, simple or branched, 4–10 dm, swollen distal to each node, some hairs glandular. Leaves: petiole 2–5 cm; blade ovate to ovate-lanceolate, 5–16 × 3–10 cm, base cuneate to truncate, apex acute to acuminate, surfaces glabrous or puberulent. Inflorescences: flowers opposite or subopposite; proximal bracts cordate, leaflike, distal usually present, subulate, 1/3–1/2 distance between base of inflorescence and proximal flowers. Pedicels to 1 mm; bracteoles 3, persistent, subulate. Flowers: calyx green, 5–8 mm, glabrous, abaxial lobes 2, triangular, 0.1–0.5 mm, adaxial 3, subulate-uncinate and indurate in fruit, 2–3 mm; corolla glabrous externally, puberulent on abaxial lip at mouth, tube 8–12 mm, abaxial lobes white to lavender, 2–4 mm, apex rounded, adaxial lavender to purple, 2–4 mm, apex acute, usually emarginate; ovule 1; style slightly exserted, glabrous; stigma lobes unequal. Achenes strongly reflexed and appressed to infructescence axis, 3–4 mm. 2n = 28.

Discussion
Variety leptostachya ranges from eastern North America to easternmost Wyoming and eastern Texas and Manitoba. Phryma had previously been reported as occurring as a garden waif in central California (C. Best et al. 1996); it has since been rejected as being naturalized in that state (http://ucjeps.berkeley.edu/cgi-bin/get_cpn.pl?37935). Fruit dispersal is presumably via animals, with attachment facilitated by the uncinate lobes of the persistent calyx (P. D. Cantino 2004).
