Leaves reduced to imbricate bracts subtending flowers. Inflorescences solitary flowers produced endogenously and rupturing through host stems. Flowers with ringed nectary at base of sepals; sepals 4 or 5, free; stylar column expanded at apex into convex, knoblike disc, this sometimes fringed or papillose; staminate flowers with 1–3 series of anthers near column apex, under margin of disc; pistillate flowers with stigmatic areas in ring along or under margin of disc.
