Description Plants cespitose, with short rhizomes; roots pale brown to reddish brown, not densely felted with root hairs; fertile culms 28–80 cm tall, trigonous, smooth, with glabrous or scabrous, purple, bladeless basal sheaths with stramineous veins. Leaves 5–10, mostly basal; blades 10–55 cm long, (1.8–)2.5–6.1 mm wide, plicate, antrorsely scabrous adaxially on main veins otherwise glabrous, the margins antrorsely scabrous, the widest leaves 2.5–6.1 mm wide; leaf sheaths 1.3–12.5 cm long, tightly enveloping culms, hispidulous with red prickle-hairs, especially on lower sheaths, strongly purple tinged near base; inner band of sheaths glabrous to hispidulous with red prickle-hairs, purple-tinged or purple-dotted on the lower sheaths, the apex concave, thickened and pubescent; ligules 2.2–8.6 mm long, acute, the free portion +- purple-tinged. Vegetative shoots 19–45 cm tall; leaves 5–7, similar to those of fertile culms; pseudoculms ca. 2.5–6 cm tall. Inflorescences (7.5–)11–41 cm long, with the upper spikes strongly overlapping and the lowest two spikes (2.5–)4.5–15 cm distant; spikes single at nodes, with all but the upper pendulous on filiform, flexuous, smooth peduncles; lowermost spikes with peduncles (1.9–)2.9–8.6 cm long, the uppermost lateral spikes sessile or nearly so; lowermost bracts with blades (3.6–)7–32 cm long and 1.7–3.8 mm wide and sheaths (1–)1.6–5.9 cm long, the uppermost bracts much reduced. Spikes 5–8, the terminal staminate proximally and distally and pistillate in the middle, rarely androgynous, the lateral androgynous, rarely pistillate. Terminal spikes 2.7–9.4 cm long; staminate portion (0–)1.3–3.1 cm long, 0.8–2 mm wide, and (0–)12–23-flowered proximally, 0.5–1.9 cm long and 8–45-flowered distally; pistillate middle portion 0.6–4.8 cm long, 3–4.5 mm wide, 10–55-flowered; peduncles 2–6 mm long. Lateral spikes 2.5–9.7 cm long, rarely compound, with secondary spikes single, androgynous, up to 1 cm long; staminate portion of lateral spikes (0–)0.3–1.8 cm long, (0–)2–40-flowered; pistillate portion of lateral spikes 1.9–9.2 cm long, 14–80-flowered. Pistillate scales 2.2–4.5 mm long, 1–1.7 mm wide, obovate, obtuse to acuminate, rarely with a scabrous-ciliate awn to 1.6 mm long, stramineous with hyaline margins and green center, 3-veined. Staminate scales 2.6–4.9 mm long, 0.7–1.4 mm wide, oblanceolate to narrowly oblong, acute to acuminate, +- ciliate distally, stramineous with hyaline margins and green center, 3-veined. Perigynia 2.7–4.5(–4.8) mm long, 0.7–1.3 mm wide, appressed to ascending, trigonous with flat, lanceolate sides, green to stramineous, glabrous, +- stipitate, 7–19-veined, contracted into a beak; beaks 0.6–1.4 mm long, glabrous or sparsely scabrous, the apex hyaline, oblique to truncate or erose. Achene 1.9–2.3 mm long, 0.7–1.1 mm wide, trigonous with flat, oblong to obovate sides, tightly enveloped by the perigynium, yellowish brown, short-stipitate. Styles withering; stigmas 3. Anthers 3, 1.1–1.8 mm long. [details]

Spikes 5–8, the terminal staminate proximally and distally and pistillate in the middle, rarely androgynous, the lateral androgynous, rarely pistillate. Terminal spikes 2.7–9.4 cm long; staminate portion (0–)1.3–3.1 cm long, 0.8–2 mm wide, and (0–)12–23-flowered proximally, 0.5–1.9 cm long and 8–45-flowered distally; pistillate middle portion 0.6–4.8 cm long, 3–4.5 mm wide, 10–55-flowered; peduncles 2–6 mm long. Lateral spikes 2.5–9.7 cm long, rarely compound, with secondary spikes single, androgynous, up to 1 cm long; staminate portion of lateral spikes (0–)0.3–1.8 cm long, (0–)2–40-flowered; pistillate portion of lateral spikes 1.9–9.2 cm long, 14–80-flowered. Pistillate scales 2.2–4.5 mm long, 1–1.7 mm wide, obovate, obtuse to acuminate, rarely with a scabrous-ciliate awn to 1.6 mm long, stramineous with hyaline margins and green center, 3-veined. Staminate scales 2.6–4.9 mm long, 0.7–1.4 mm wide, oblanceolate to narrowly oblong, acute to acuminate, +- ciliate distally, stramineous with hyaline margins and green center, 3-veined. Perigynia 2.7–4.5(–4.8) mm long, 0.7–1.3 mm wide, appressed to ascending, trigonous with flat, lanceolate sides, green to stramineous, glabrous, +- stipitate, 7–19-veined, contracted into a beak; beaks 0.6–1.4 mm long, glabrous or sparsely scabrous, the apex hyaline, oblique to truncate or erose. Achene 1.9–2.3 mm long, 0.7–1.1 mm wide, trigonous with flat, oblong to obovate sides, tightly enveloped by the perigynium, yellowish brown, short-stipitate. Styles withering; stigmas 3. Anthers 3, 1.1–1.8 mm long. [details]Ecology Carex perlonga occurs in moist forests and barrancas in Hidalgo and Veracruz between 1600 and 2000 m.
