Description Culms 55–200(310) × 2–5 mm. Basal sheaths red-brown to dark purple. Leaves 70–130(170) cm × 5.5–12.0 mm largest ones, longer than the culms, dense papillose, oldest ones orangey-brownish at the base. Inflorescence panicle, 25.5–40.5 cm long, with 25–65(80) androgynous spikes, spreading or dropping. Proximal-most bract 26.0–45.2 cm × 4–10.4 mm, subequal or longer than the inflorescence. Spikes (3.3)4.5–12.6 cm × 3.4–7.5 mm, linear to oblong, densely flowered, the distal 1/4–1/10 staminate, sometimes 2-branched at the base, with about 180–220(250) fe-male flowers, peduncles smooth or scabrous, usually shorter than the spikes, but sometimes subequal or much longer. Pistillate glumes 3.1–5.4 × (0.6)1.0–2.2 mm, elliptic to oblong, acute, muticuous, purplish-black with a light-yellow middle lon-gitudinal strip, hyaline margins extremely narrow or absent, when present, only on the distal 2/3 of the glume. Stigmas 3. Utricles 3.7–5.3 × 0.9–1.5 mm, ovate to ellip-tic, smooth, stramineous, green-brownish or partially dark purple, nerves raised, constricted at the apex into a 0.9–1.4 mm long recurved beak, smooth or scabridu-lous, bifid, teeth 0.3–0.5(0.7) mm. Nutlets 1.9–2.5 × 0.8–1.2 mm, elliptic. [details]

Distribution Carex jovis is an almost strictly Central American species, distributed all along the Central American and Talamanca Cordilleras, from southern Mexico (State of Chiapas) to northern Panamá (Province of Bocas del Toro). We also have detected one single South American population from the Cordillera Occidental of Colombia (Caldas, Medellín). [details]

Etymology From the Latin jovis, a refence to Jupiter, chief Roman deity, as this species is unu-sually large among the representatives of the genus. Indeed, it has the largest culms recorded for any Carex species (>3 m). [details]

Etymology From the Latin jovis, a refence to Jupiter, chief Roman deity, as this species is unu-sually large among the representatives of the genus. Indeed, it has the largest culms recorded for any Carex species (>3 m). [details]
Habitat Moist slopes of evergreen cloud forest, it can also appear on shrub-tree páramo, meadows and even sometimes on gullies. It is always related to wet or moist habi-tats. 1330–3335 m. [details]
