Rhynchospora harveyi
Rhynchospora harveyi var. culixa
Harvey's beaksedge
Georgia beaksedge
erect to excurved, leafy, obscurely trigonous, slender.
mostly excurved, slender.
spreading to ascending, shorter than culm, crowded toward culm base;
blades linear, proximally flat, 1–3 mm wide, gradually involute, apically trigonous, subulate.
spikelet clusters 1–4, dense to open, mostly irregularly turbinate;
peduncles ascending, branches spreading to erect, ultimate branches with many spikelets; leafy bracts setaceoustipped, usually exceeding all clusters, or at least all but the distal.
spikelet clusters mostly loose, branching lax, ascending to arching, ultimate branches with few spikelets; leafy bracts setaceoustipped, these and bractlets exceeding proximal clusters, exceeded by distal.
light redbrown or brown, broadly ellipsoid to lanceoloid, 3–4 mm, apex acute to acuminate;
fertile scales ovate to obovate or suborbiculate, 2–3.5 mm apex acute to rounded or emarginate, midrib included or exserted as mucro.
prevalently lanceoloid, 3–4 mm, apex acute or acuminate;
fertile scales ovate, 2.5–3.5 mm, apex acute, mostly mucronate.
perianth bristles mostly 6, rarely reaching fruit midbody, antrorsely barbellate.
perianth bristles 6, short, reaching at most to fruit midbody, antrorsely barbellate.
mostly 1 per spikelet, 2–2.5 mm, body dark brown, obovoid to subglobose, tumid or lenticular, 1.5–1.7 mm, transversely finely rugose to nearly level, intervals with very small, pitlike alveoli.
1(–2) per spikelet, 2–2.2 mm;
body brown or redbrown, obovoid, lenticular, 1.5–1.6 mm;
surfaces with numerous, wavy lines of tiny pitlike, short-rectangular, vertical alveolae, separated by numerous, transverse, undulate, low, broad ridges;
tubercle with narrow buttress, lowconic, 3–5 mm.

Of conservation concern.
Variety culixa is distinguished from var. harveyi by a lower, more slender habit, by sparser inflorescences, the terminal cluster overtopping subtending leafy bract, and by the comparatively flatter fruit. Its fruit body surfaces have broader, low, smooth, and pale transverse ridges.

1. Fruit body broadly obovoid to suborbicular, medially with mostly isodiametric tiny alveoli or pits, or minutely raised reticulate in an almost honeycomb pattern of alveolae, or simply evenly finely cancellate; ultimate spikelet complexes with clusters on stiffish branchlets, usually dense and exceeded at least by subulate tips of subtending leafy bract and bractlets. | var. harveyi |
1. Fruit body obovoid, lenticular, medially with oblong or roundish pitlike alveoli, intervals between contiguous transverse rows forming shallow, broad, pale, smooth ridges; ultimate spikelet clusters more sparse, on more slender, lax, erect to excurved branches and exceeding subtending bracts and bractlets. | var. culixa |
