Type
Type: Sri Lanka, Kőnigs.n. (holotype LD).
Morphology General Habit
Annual, tufted
Morphology Culms
Culms, few to many closely packed, 5 – 50 cm long (including overtopping erect, inflorescence bract), 0.4 – 1.8 mm wide, ridged, triangular to almost terete
Morphology Leaves
Leaves sheaths 1 – 2 cm long, often lowest enclosing basal female floret, style 3-branched, 15 – 20 mm long, basal nutlet wrinkled, 2 – 2.5 × 1.4 – 2 mm, blades absent or if present up to 30 cm long, flat or folded
Morphology Reproductive morphology Inflorescences
Inflorescence consisting of clusters of spikelets, appearing pseudolateral, overtopped by inflorescence bract, shorter than culm
Morphology Reproductive morphology Inflorescences Spikelets
Spikelets 1 – 20, sessile or shortly pedunculate, 4 – 10 × 2 – 2.5 mm, ovoid, acute
Morphology Reproductive morphology Inflorescences Bracts Glume
Glumes 2 – 3 mm long, ovate to broadly boat-shaped, pale brown with reddish streaks, green midrib, mucronate, margin ciliate apically
Morphology Reproductive morphology Flowers Perianth
Perianth absent
Morphology Reproductive morphology Flowers Androecium Stamens
Stamens 3
Morphology Reproductive morphology Flowers Gynoecium Style
Style 3-branched
Morphology Reproductive morphology Fruits
Aerial nutlet, broadly ovoid, trigonous or weakly so, turning black at maturity, 1.1 – 1.4 × 0.8 – 1.3 mm, surface markedly rugose.
Distribution
Throughout the Old World Tropics. Africa: Angola, Botswana, Central African Republic, Equatorial Guinea, Ethiopia, Ghana, Kenya, Mali, Malawi, Mozambique, Namibia, Nigeria, Senegal, Somalia, Tanzania & Uganda. Eastern Asia to Indo-China, Malay Islands, Philippines & Northern Australia.
Ecology
Water holes, swamps, lake & lagoon margins; alt. 0 – 1300 m.
Conservation
Least Concern (LC) due to its extensive distribution.
Note
The species is usually distinguished from both subspecies of Schoenoplectiellaerecta by a combination of three style branches and a trigonous nutlet. The surface of the nutlet is otherwise the same as that of S. erecta subsp. raynalii.
