slender beaksedge

Habit Plants perennial, densely cespitose or solitary, 10–100 cm; rhizomes absent.
Culms

mostly lax, ascending to leaningexcurved, leafy, linear to filiform, terete.

Leaves

shorter than culm;

blades ascending, filiform to narrowly linear, proximally flat, 0.5–1.5(–2.5) mm wide, margins distally strongly involute, apex trigonous, tapering.

Inflorescences

spikelet clusters 1–3(–4), proximalmost distant, dense to sparse, narrowly turbinate to hemispheric;

peduncles and branches ascending; leafy bracts linearsetaceous, mostly overtopping clusters.

Spikelets

redbrown, ovoid to lanceoloid, (3.5–)4–5 mm, apex acute;

fertile scales ovate, 3–4.5 mm, apex acute, mucronate to awnedcuspidate.

Flowers

bristles 6, mostly reaching tip of tubercle or beyond, antrorsely barbellate.

Fruits

1–3 per spikelet, (2.5–)3–3.5(–4.1) mm;

body dark brown with small pale center, lenticular, broadly ellipsoid to suborbicular, 1.3–2.1 × 1.3–1.5 mm, smooth, margins narrow, flowing into tubercle;

tubercle triangular-subulate, compressed, mostly 1.5–2 mm.

Discussion

Through the southern coastal plain are widerleaved examples of Rhynchospora gracilenta that are sparingly cespitose to solitary-stemmed, often with but a single terminal inflorescence with dense clusters of spikelets (var. diversifolia). That would be a tenable designation were it not for the large numbers of populations with intermediate habit.
