Morphology General Habit
Annuals or perennials, with or without leaves
Morphology Culms
Culm scapose or nearly so, with or without a node above the base
Morphology Leaves
Leaves usually reduced to sheaths
Morphology Reproductive morphology Inflorescences Bracts
Involucral bracts leafy and spreading or more usually stem-like and in the same direction as the stem, with or without transverse septa
Morphology Reproductive morphology Inflorescences
Inflorescence a dense apparently lateral, but really terminal, cluster of few to many spikelets, less often a more open anthela
Morphology Reproductive morphology Inflorescences Spikelets
Spikelets with many bisexual flowers subtended by spirally arranged glumes
Morphology Reproductive morphology Flowers Perianth
Perianth bristles absent or present and of barbed or smooth needle-like bristles, or more flattened and plumose
Morphology Reproductive morphology Flowers Androecium Stamens
Stamens usually 3.
Morphology Reproductive morphology Flowers Androecium Stamens Filaments
Filaments often persistent
Morphology Reproductive morphology Flowers Gynoecium Style
Style 2–3-branched
Morphology Reproductive morphology Fruits
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.
