Tepals 3-5, mostly free; bracts, bracteoles and tepals with scarious margins or entirely scarious; bracteoles falling off with the perianth or persistent; perianth usually enclosing the fruit and falling off with it, rarely persistent. Stamens as many as petals and opposed to them, rarely fewer; filaments free, or connate below, or almost entirely united in a cup or tube, with or without interposed dentiform, subulate, linear or short and broad pseudo-staminodes; anthers dorsifixed or inserted in a basal cleft, 1—2-celled (2- or 4-locellate). Ovary superior, 1-celled; ovules 1 or more, basal; funicles short or long.
