    Cyperaceae, K Hoenselaar, B. Verdcourt & H. Beentje. Hypolytrum, D Simpson. Fuirena, M Muasya. Flora of Tropical East Africa. 2010

    Annuals or perennials, with or without leaves
    Culm scapose or nearly so, with or without a node above the base
    Leaves usually reduced to sheaths
    Involucral bracts leafy and spreading or more usually stem-like and in the same direction as the stem, with or without transverse septa
    Inflorescence a dense apparently lateral, but really terminal, cluster of few to many spikelets, less often a more open anthela
    Spikelets with many bisexual flowers subtended by spirally arranged glumes
    Perianth bristles absent or present and of barbed or smooth needle-like bristles, or more flattened and plumose
    Stamens usually 3.
    Filaments often persistent
    Style 2–3-branched
    Nutlet obovoid to round, usually apiculate, smooth or ridged.
    Annual species may have basal flowers ± hidden in the lower leaf sheaths, with very long styles protuding from the sheaths, and nutlets larger than those of the aerial florets. Lye described Schoenoplectiella out of Schoenoplectus for those taxa that are more closely related to Eleocharis than to Schoenoplectus. These differ in mostly being annual and producing solitary female flowers in the basal leaf sheaths.
