Mendocino Sedge

Carex mendocinensis Olney ex Boott

Comments

provided by eFloras
Occasional sterile hybrids between Carex mendocinensis and C. gynodynama are found where the species grow together. Specimens from the northern part of the range tend to have pubescent leaf sheaths and perigynia that taper more gradually to the beak.

Description

provided by eFloras
Plants densely cespitose. Culms dark maroon at base; flowering stems 25–80 cm, much longer than leaves at maturity, 1–1.8 mm thick, glabrous but scabrous on angles, especially within inflorescence. Leaves: basal sheaths maroon, bladeless, glabrous on back; others grading from maroon to green on back, brown-hyaline and usually red dotted on front, glabrous or often pubescent near apex; blades flat, 2.5–5.5 mm wide, usually less than 4 mm wide, glabrous or sparingly rough-hispidulous on 1 or both surfaces, margins scabrous, especially distally. Inflorescences: peduncles of proximal spikes 0–65 mm and finely scabrous; peduncle of terminal spike 0–12 mm, scabrous; proximal bracts equaling or exceeding inflorescences; sheaths 8–40 mm; blades 1–4 mm wide. Lateral spikes 3–5, 1 per node, well separated, erect or arching at maturity, pistillate with 20–45 perigynia attached 0.5–2 mm apart, rarely the distal staminate, linear to narrowly cylindric, 10–60 × 2.5–6 mm. Terminal spike staminate, rarely with a few perigynia, sessile or pedunculate, 18–38 × 1.2–4 mm. Pistillate scales with green midrib and broad pale hyaline margins suffused with reddish or golden brown, broadly ovate, shorter than mature perigynia, apex acute to rounded, sometimes cuspidate, margins ciliate distally, otherwise glabrous. Perigynia green to golden green, usually blotched or dotted with dark red, 2-ribbed and finely 12–15-veined, veins more obvious on abaxial side, loosely enveloping achene, oblong-lanceolate, 2.7–5 × 0.8–1.8 mm, membranous, base acute, apex tapering to beak, sparsely pubescent toward apex; beak minutely bidentate, 0.3–1 mm, ciliate between apical teeth. Achenes sessile, 1.6–2.5 × 0.9–1.5 mm. 2n = 56, 58, 60.
