Inflorescence a terminal, congested, spicate-capitate, bracteate cyme. Flowers: calyx 3–6 mm long; corolla white, salverform; tube 6–9 mm long, surpassing the calyx; lobes 3–5 mm long; stamens included with filaments shorter than the anthers. Capsule 3–5 mm long with several seeds per locule (Lesica et al. 2012. Manual of Montana Vascular Plants. BRIT Press. Fort Worth, TX).
