Staminate flowers 3-merous, actinomorphic: Sepals 6, the exterior bracteoliform, the interior conspicuously larger, imbricate; petals 6, so greatly involute as to almost conceal the stamens by forming a "pseudodisc"; stamens 6, free, dehiscence longitudinal. Pistillate in-florescence axillary, racemose or sessile and umbelliform. Pistillate flowers: Sepals and petals similar to the staminate; staminodia 6; carpels 3, free; stigma sub-sessile or sessile, lingulate.
