M. Thulin et al. Flora of Somalia, Vol. 1-4 [updated 2008] https://plants.jstor.org/collection/FLOS

Morphology General Habit
Small annuals or large perennials; stem terete or triangular, with or without a node above the base
Morphology Leaves
Leaves mostly basal; blades present or absent; main inflorescence-bract leafy or more commonly stem-like and continuing in the direction of the stem, with or without transverse septa
Morphology Reproductive morphology Inflorescences
Inflorescence usually a dense apparently lateral cluster of few–many spikelets, more rarely a lax terminal anthela
Morphology Reproductive morphology Inflorescences Spikelets
Spikelets ovate to lanceolate, usually with numerous bisexual flowers subtended by spirally arranged glumes, rarely of 1–10 flowers only
Morphology Reproductive morphology Inflorescences Bracts Glume
Glumes ovate to broadly cordate, glabrous or minutely scabrid, but often with longer hairs along margin
Morphology Reproductive morphology Flowers Perianth
Perianth of usually 6 needle-like bristles with or without recurved barbs, or of 4–5 flattened plumose segments (in S. subulatus only)
Morphology Reproductive morphology Flowers Androecium Stamens
Stamens usually 3
Morphology Reproductive morphology Flowers Gynoecium Style
Style with 2–3 stigmas
Morphology Reproductive morphology Fruits
Nutlet obovate to nearly orbicular, triangular or biconvex, smooth or transversely wrinkled
Morphology Reproductive morphology Flowers
Annual species often with basal cleistogamous flowers ± hidden in the lower leaf-sheaths and with very long styles with the stigmas protruding from the opening of the sheaths, and with nutlets larger than those produced in aerial spikelets.
Distribution
Genus of about 30 species in all tropical and temperate parts of the world, sometimes included in Scirpus L.

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.
Note
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.
