W. Boott

Bot. Gaz. 9: 85. 1884.

Treatment appears in FNA Volume 23. Treatment on page 231. Mentioned on page 206, 223, 230.

Plants perennial, cespitose, 70–110 cm; rhizomes absent. Culms erect to excurved, leafy, obscurely trigonous, slender. Leaves spreading to ascending, shorter than culm, crowded toward culm base; blades linear, proximally flat, 1–3 mm wide, gradually involute, apically trigonous, subulate. Inflorescences: 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. Spikelets 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. Flowers: perianth bristles mostly 6, rarely reaching fruit midbody, antrorsely barbellate. Fruits 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 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.

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.
