Morphology

Hemiparasitic annual; stems glabrous or nearly so, simple or branched; leaves linear; pedicels, 1-4 mm; calyx lobes 2-3.5 mm long, 0.4-1 times as long as the tube; corolla 1-2(-2.3) cm long, the upper lobes only slightly spreading; pollen sacs 1.4-2 mm.

Wetland indicator: NA

This species is sometimes treated as a variety of A. purpurea (var. parviflora) since it differs mainly in size (corollas mostly 2 cm or less long), although the lobes of the calyx are relatively long relative to A. purpurea. I took this photo in northeastern IL many years ago and recall at the time that the plant appeared to be a diminutive A. purpurea. The plant behind it is Salix discolor which has leaves mostly 1.5-3.5 cm wide.
