Por C.D. Adams.

Anuales o perennes de talla corta a mediana. Tallos cespitosos o próximos entre sí, brotando de un rizoma rastrero, erectos, generalmente teretes y acostillados, a veces aplanados apicalmente, foliosos en la base. Hojas espiraladas, raramente ( F. littoralis) dísticas, filiformes, aplanadas o involutas, a menudo uniformemente acostilladas en el envés y obtusas en la punta, generalmente más cortas que el escapo florífero, unión de la vaina y la lámina con o sin una lígula. Inflorescencia un corimbo umbeliforme, simple o compuesto; brácteas foliiformes. Espiguillas bisexuales, sésiles y pediceladas, en cimas pequeñas corta o largamente pedunculadas, a menudo con desarrollo prolongado. Glumas espiraladas, deciduas, las más bajas generalmente estériles, redondeadas en el envés o carinadas, la costilla media a menudo verde, la punta excurrente en un mucrón o cúspide corto u obtusa a emarginada; raquilla persistente. Flores bisexuales; perianto ausente; estambres 1-3; estigmas 2-3; estilo cuando 2-fido generalmente alargado, aplanado y fimbriado ciliado, cuando 3-fido subterete, agrandado en la base. Aquenios lenticular-obovoides a subtrígonos, redondeados u obtusos en la punta, sin la base del estilo persistente pero generalmente apiculados, los bordes generalmente con puntos diminutos horizontal-rectangulares en hileras verticales, a menudo claros y lustrosos.

Espiguillas solitarias a numerosas, mayormente cilíndricas u ovoides, en arreglos compuestos de címulas o glomérulos, densos a abiertos, involucrados; escamas varias a numerosas, imbricadas en espiral, raramente dísticas, todas excepto la inferior fértiles, con flósculos perfectos; perianto ausente; estambres 1–3; carpelos 2 ó 3, estilo bífido o trífido, fimbriado (raramente liso en la parte proximal), base aplanada o gruesa, tempranamente deciduo. Fruto obovoide-lenticular a triquetro o tumescente, variadamente labrado.

    Herbs, annual or perennial, usually cespitose, rhizomatous or not. Culms sometimes solitary, scapose, stiff or flaccid, terete, compressed, or 3–5-angled, coarse or fine. Leaves basal, distichous or polystichous; sheaths open apically, shorter than blade, with broad scarious margins; ligule absent at junction with blade or, if present, of erect short hairs, transverse, continuous or interrupted; blades flat or variously folded, terete, or sulcate, not prominently keeled on abaxial surface, the widest not more than 2 mm wide. Inflorescences simple or compound anthelae, rarely capitate; spikelets 1–80+, rarely single; involucral bracts 2–5, spreading or rarely erect, scalelike or leaflike. Spikelets mainly ovoid to lanceoloid or cylindric, sometimes compressed; scales 8–100+, spirally arranged, each subtending flower or proximal 1–2 empty. Flowers bisexual; perianth absent; stamens 1–3; styles flattened or subterete, 2–3-fid, base enlarged, deciduous. Achenes biconvex or trigonous, reticulate-honeycombed.

    Herbs, annual or perennial, medium sized, often rhizomatous. Culms usually tufted, slender, 3- or 5-angled or flattened. Leaves basal, sometimes reduced to a bladeless sheath; ligule if present membranous or a fringe of hairs; leaf blade linear, filiform, or rarely ensiform, usually dorsiventrally compressed and canaliculate, often adaxially cellular-reticulate. Inflorescences terminal, a simple, compound, or decompound anthela, rarely capitate or reduced to 1 terminal spikelet. Spikelets solitary or fascicled, ovoid, ellipsoid, or subglobose, terete or flattened, with several to many flowers. Glumes spirally imbricate, distichous, or only basal ones distichous and apical ones spirally imbricate, often with 1 or more veins forming an abaxial keel and sometimes extending into an apical mucro or arista. Flowers bisexual. Perianth bristles absent. Stamens 1-3. Style not persistent on nutlet, basally enlarged. Nutlet sometimes stipitate, biconvex, 3-sided, or almost terete, either reticulate, verruculose, or both.

    "Spikelets several to many in simple or compound, often umbelliform cymes or glomerules, forming a terminal infl subtended by a cluster of sheathless, leafy or scarious invol bracts; scales spirally imbricate; fls perfect; perianth none; stamens 1–3; style 2–3-cleft, wholly deciduous, usually enlarged at base, the unbranched part often flattened and fimbriate especially distally; radicle lateral; herbs with a few long, grass-like lvs near the base, the sheath entire or short-ciliate. 200, warm reg. Spp. 3–5 are closely related and might with some reason be treated as well marked vars. of the tropical F. spadicea (L.) Vahl."
