This plant agrees in its essential characters with the plant described by Linnaeus 
and Michaux, ani subsequently by Pursh and Elliott. A low perennial, the stem 
prostrate, 6 to 8 inches long, profusely branched from the base; the slender grooved 
stems hirsute on the angles; the leaves membranaceous, ovate to ovate-lanceolate, 
attenuate toward the base into a winged, ciliate, distinct petiole; the flowers in 
close axillary and terminal clusters, the calyx lobes foliaceous, longer than the glo- 
bose, hirsute capsule. 
Type locality: ‘Hab. in Virginia.”

lary clusters, the calyx lobes as long as or shorter than the smoothish capsules.
