    Pistil
    Ovary with a solitary pendulous ovule, the ovary wall very thin in fruit; style slender; stigma small, truncate-capitate
    Seeds
    Endosperm copious. Entire flower with bracteoles falling with the ripening of the cylindrical seed, the deflexed bracts persistent
    Habit
    Herbs with opposite, petiolate, entire leaves
    Inflorescences
    Inflorescence a ± slender spike, terminal on the stem and branches, the flowers at first congested and ± patent, finally usually laxer and deflexed; bracts deltoid or ovate, the midrib excurrent in a spine
    Flowers
    Flowers solitary in the bracts, hermaphrodite, bibracteolate
    Perianth
    Perianth-segments 4–5, 1–3(–5)-nerved, narrowly lanceolate, acuminate, aristate with the excurrent midrib, indurate in fruit especially at the base
    Bracteoles
    Bracteoles spinous-aristate with the excurrent midrib, the lamina forming short and free to longer and adnate membranous wings
    Stamens
    Stamens 2–5; filaments filiform, monadelphous, alternating with quadrate to broadly quadrate-spathulate pseudostaminodes, these simple and dentate or fimbriate, or furnished with a variably developed dorsal scale; anthers bilocular
