Phryma leptostachya

Phryma leptostachya, or lopseed, is a perennial herb.[1] The genus is native to eastern North America (roughly, everywhere east of the Rocky Mountains[2]) and Asia (Japan, Nepal, India and West Pakistan[3]), and consists of either one or two species, depending on whether the American and Asian species are considered separate or not.[4]

The plant stands about 0.3 to 1.0 meters tall, and the inflorescences bear a number of small (4 mm) tube-shaped white to pink flowers.[1]

Although it has sometimes been classified in the family Verbenaceae,[1] 21st century research has placed it in a small family (Phrymaceae) along with Mimulus (monkey flowers) and a small number of other genera which had formerly been in the Scrophulariaceae.[4]
