Description
The correct name for this species is Rhynchospora pineticola. A new page will be made for that name and edits made under that entry.

Rhynchospora pineticola C. B. Clarke, Bull. Misc. Inform. Kew, Addit. Ser. 8: 40. 1908.
Phaeocephalum intermedium (Chapman) House; Rhynchospora intermedia (Chapman) Britton 1892, not Beyrich ex Kunth 1835; R. plumosa Elliott var. intermedia Chapman
Plants perennial, mostly densely cespitose, 20–70 cm, base deep rich red brown; rhizomes absent. Culms erect to ascending, leafy, stiff. Leaves shorter than scape; blades narrowly linear, (1–)2–3 mm wide, margins involute, apex trigonous, tapering. Inflorescences: clusters 1–2, if 2 then close together, dense, broadly turbinate to hemispheric or lobed globose; primary leafy bract linear, stiff, exceeding clusters. Spikelets light to dark red brown, lance ovoid, 3.5–6 mm, apex acuminate; fertile scales ovate, convex, 3–3.5(–4) mm, apex acuminate, low midrib excurrent or not. Flowers: perianth bristles 6, reaching at least to tubercle base, plumose from base to more than 1/2 length of fruit body. Fruits 1(–2) per spikelet, (2–)2.5–2.8(–3) mm; body red brown or brown, tumidly obovoid, (1.5–)2–2.2 × 1–1.7 mm; surfaces interruptedly transversely rugulose; tubercle broadly conic, 0.5–0.8(–1) mm, base broadly 2 lobed, apex often apiculate. Fruiting spring–fall or all year. Sands and sandy peat of bog margins, pinelands and pine saw palmetto flats among wiregrass; 0–200 m; Fla.; West Indies (Cuba).
Rhynchospora pineticola is distinguished from taller extremes of R. plumosa by its thicker leaves and scapes and its longer spikelets and fruit. Its bases are a deep rich red-brown rather than the pale brown or dull deep brown of R. plumosa.
