Leaves opposite, linear to broadly lanceolate, up to 7 cm. long and 1 cm. wide.
Inflorescence a loose, few-flowered cluster, leafy-bracteate at least below; calyx with nearly flat, translucent intervals between the herbaceous segments, 5 lobed; corolla pink to white, the tube 1-1.5 cm. long, scarcely surpassing the calyx, the 5 lobes 1-1.5 cm. long, usually notched at the tip; style very short, 0.5-2 mm. long, often shorter than the 3 linear stigmas; ovary superior.
