    Type
    Type: Guyana, Schomburgk 685 (B†, holo.)
    Habit
    Perennial. Leafy
    Culms
    Culms solitary (rarely 2–3 together), on tough creeping stolons. Culms rounded, often trigonous at the base of the inflorescence, with indistinct longitudinal ridges, 20–82 cm long, 0.5–1.5 mm wide, basally swollen and covered with stiff scales and old leaf sheaths, glabrous or sometimes with long transparent hairs
    Leaves
    Leaf blade linear, flat or v-shaped, stiff, 7–35 cm long, 2.1–4.5 mm wide, glabrous or the margins and midrib scabrid, both surfaces with long transparent hairs Leaf sheath pale green to brown, 1.5–8 cm long. Leaves spread along the culm, up to 40 cm long.
    Bracts
    Involucral bract 1. Leaf-like, 1–3.5 cm long, 0.9–1.8 mm wide, with long transparent hairs.
    Inflorescences
    Inflorescence simple to compound, corymbose, 2–6 primary branches, 0.5–2.7 cm long.
    Glume
    Upper 30–50 glumes (may appear to be much less when young spikelets are studied) fertile, with bisexual flowers, closely imbricate, ovate and concave, 4.6–6.4 mm long, 2–4.3 mm wide, with midrib ending in a short acumen, glabrous. Lower 6–8 glumes sterile, becoming successively larger upwards. Glumes white, sometimes with brown dots at base.
    Spikelets
    Spikelet axis with round projections, the glume bases intricately folded between them Spikelets solitary, at the end of primary or secondary branches, ovoid, 5.5–12 mm long, 3–5.5 mm wide, with up to 50 glumes.
    Perianth
    Perianth absent
    Stamens
    Stamens 3: filaments 3.8–5.3 mm long.
    Anthers
    Anthers 2.1–3 mm long
    Style
    Style with 2 branches
    Fruits
    Nutlet whitish to yellowish brown (darker brown when immature), rounded, 1.4–1.7 mm long, 1.3–2.1 mm wide, transversely wavy, with a large overhanging spongy crown, whitish, 0.6–1 mm long, somewhat broader than the nutlet itself; not all nutlets of a single spikelet develop.
    Ecology
    Seasonally wet to permanently flooded grasslands, lake shore and swamps; sea-level up to 1830 m
    Conservation
    Least Concern (LC) due to its wide distribution and common habitat
    Note
    This is an easily recognized species due to its solitary white spikelets. With its many glumes per spikelet it is rare among Rhynchospora, a genus often described as few-flowered.
