 and Michaux, and 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.
