Cyperus serotinus is a species of sedge that is native to parts of Europe and Asia. [1]
The species was first formally described by the botanist Christen Friis Rottbøll in 1773. [1]
A moderately tall (30-70(120) cm) long-creeping sedge (with tubers) with solitary, triangular stem, leaves broad (4–10 mm), minutely rough-toothed (antrorsely-scabrid), diverging from the stem a little distance up, leaving a bare higher stretch of stem, the leaves as long as the stem or a little more. The 2-3(5) leafy bracts under the inflorescence resemble the leaves and much exceed the inflorescence.
The inflorescence is clearly terminal and composed usually of a number (5-10(15)) of unequal radiating axes ("rays", to 15 cm), themselves divided, with each ultimate axis unwinged, usually holding a fair number (7-14) of flat spikelets that are well-separated, forming a loose or slightly congested ladder of stalked, projecting spikelets, with even the end spikelets separated from neighbouring ones.
The spikelets are 2–3.5 mm wide ((5)10-15(30) mm long), each composed of 8-30 florets with broad scale-like glumes (2-2.5 x 1.5–2 mm) with wide pale margins and rounded tip, each floret maturing to hold a dark nut (1-1.2 mm, 2-faced, there being 2 barely-protruding stigma for the flower). .

A raceme or racemoid is an unbranched, indeterminate type of inflorescence bearing flowers having short floral stalks along the shoots that bear the flowers. The oldest flowers grow close to the base and new flowers are produced as the shoot grows in height, with no predetermined growth limit. Examples of racemes occur on mustard and radish plants.
Cyperus is a large genus of about 700 species of sedges, distributed throughout all continents in both tropical and temperate regions.
Cyperus esculentus is a species of plant in the sedge family widespread across much of the world. It is found in most of the Eastern Hemisphere, including Southern Europe, Africa and Madagascar, as well as the Middle East and the Indian subcontinent. C. esculentus is cultivated for its edible tubers, called earth almonds or tiger nuts, as a snack food and for the preparation of horchata de chufa, a sweet, milk-like beverage.
In botany, a glume is a bract below a spikelet in the inflorescence of grasses (Poaceae) or the flowers of sedges (Cyperaceae). There are two other types of bracts in the spikelets of grasses: the lemma and palea.
Cyperus rotundus is a species of sedge (Cyperaceae) native to Africa, southern and central Europe, and southern Asia. The word cyperus derives from the Greek κύπερος, kyperos, and rotundus is from Latin, meaning "round". The earliest attested form of the word cyperus is the Mycenaean Greek 𐀓𐀞𐀫, ku-pa-ro, written in Linear B syllabic script.
Sporobolus heterolepis, commonly known as prairie dropseed, is a species of prairie grass native to the tallgrass and mixed grass prairies of central North America from Texas to southern Canada. It is also found further east, to the Atlantic coast of the United States and Canada, but is much less common beyond the Great Plains and is restricted to specialized habitats. It is found in 27 states and four Canadian provinces.
Cyperus bulbosus is a species of sedge found across Africa, the Middle East, Indian subcontinent, Southeast Asia, and Australia. In Australia, it is commonly called Nalgoo or (Australian) bush onion or "wild onion", but is not related to the onion or other Alliaceae. It is a component of Australian bushfood, but is considered an agricultural weed in other areas.
Rhynchospora alba, the white beak-sedge, is a plant in the sedge family, Cyperaceae. It is a tufted herbaceous perennial around 50 cm tall, with white inflorescences that flower in August. The fruit of the sedge is a small achene with a characteristic beak-like cap. It is dispersed by wind or falls by gravity, leading to individuals existing in tight clumps. The species favours wet, acidic and nutrient poor soils, thriving in Sphagnum-dominated bogs, but also peaty grasslands. As such, it is often used as a positive indicator for bog and mire ecosystem health.
Cyperus bipartitus, commonly known as slender flatsedge, river cyperus, or the shining flatsedge, is a common species of sedge. The name "slender flatsedge" also applies to Cyperus gracilis.
Cyperus difformis is a species of sedge known by several common names, including variable flatsedge, smallflower umbrella-sedge and rice sedge. This plant is native to southern Europe, most of Africa and Asia, and Australia, and it is naturalized in other areas of the world, including large parts of the Americas.
Carex klamathensis is a rare species of sedge known by the common name Klamath sedge. It is known from 15 or fewer populations in southern Oregon and three populations in the Klamath Region of northern California. It was described to science only in 2007. Its habitat includes fens and other wet habitat, on serpentine soils. It was discovered independently by botanists Peter Zika and Lawrence Janeway.
Carex eburnea, known as ivory sedge, ebony sedge, and bristleleaf or bristle-leaved sedge, is a small and slender sedge native to North America, from Alaska and Newfoundland south to central Mexico.
Cyperus longus is a species of sedge known by the common names of sweet cyperus and water rush in Africa, or in Britain galingale.
Actinoschoenus arthrostyloides, commonly known as hairy actinoschoenus, is flowering plant in the sedge family, Cyperaceae, that is native to Western Australia throughout parts of the Kimberley region.
Cyperus gilesii, commonly known as Giles' flat-sedge, is a sedge of the Cyperaceae that is native to Australia.
Rytidosperma bipartitum, the leafy wallaby grass, is a perennial species of grass found in south eastern Australia. Usually found on the heavier clay or on loamy soils in open eucalyptus woodland. The habit is somewhat variable, erect and densely tufted. The grass may grow up to 0.7 m tall.
Carex arctogena is a member of the sedge family (Cyperaceae) which grows in high alpine areas. It is one of the few "bipolar" species; it has populations in Greenland, Scandinavia, Russia, Canada and southern South America. Plants in the far north and south appear to be genetically identical, having taken advantage of a similar niches on opposite ends of the globe.
Carpha alpina, commonly known as small flower-rush, is a tufted perennial sedge from the family Cyperaceae. It is found primarily in south-east Australia and both islands of New Zealand, but also in Papua New Guinea.
Cyperus capitatus, known as Capitate Galingale is a species of sedge that is native to coasts of the Mediterranean and close by; it has no subspecies.
Rhynchospora gracillima is a widespread species of sedge.
