  Flowering Plant Families, UH Botany
The Cyperaceae are grasslike, herbaceous plants comprising about 70 genera and 4,000 species, commonly found in wet or saturated conditions.
The leaves are alternate, commonly in 3 ranks, usually with a closed sheathing base and a parallel-veined, strap-shaped blade.

The Cyperaceae (sedges) form one of the larger and more diverse plant families being actively researched at the Royal Botanic Gardens, Kew, comprising c.
As a result the Kew herbarium has a collection of c.100,000 Cyperaceae specimens which is unrivalled elsewhere and continues to grow at some 2,000 to 3,000 specimens per year.
Cyperaceae Newsletter published by the Royal Botanic Gardens, Kew and Gent University (Belgium) contains news of current research and short papers on sedges together with comprehensive lists of new names and bibliographies of newly published literature.

The Cyperaceae as a whole were found to be monophyletic in Muasya et al.
At each recognized taxonomic rank within the Cyperaceae - family, subfamily, tribe, genus, subgenus, section, and species - researchers have identified some monophyletic groups and been forced to lump the remaining taxa into paraphyletic or polyphyletic groups.
Within the Cyperaceae as a whole, the subfamily and tribal classifications are largely inadequate, even with molecular data that is available to date.

Eriocaulaceae, Poaceae, Cyperaceae and Juncaceae at least have lateral roots originating opposite the phloem of the vascular tissue, in Restionaceae and Bromeliaceae they originate opposite the xylem.
Cyperaceae and relatives and Eriocaulaceae and relatives are sister taxa).
Cyperaceae are herbs with solid, sharply three-angled stems and leaves with closed sheaths.

 pollen grain morphology cyperaceae   (Site not responding. Last check: 2007-10-20)
Cyperaceae are abundant in aquatic vegetation, in alpine meadows, and as understory plants in mesic forests.
The pollen of aquatic plants is not routinely included in the pollen sum to avoid local bias, so Cyperaceae pollen should be excluded if it originates from aquatic plants, but it should be included if is from plants growing in upland settings.
Thus, the choice of whether to include it in the sum may rest on an assumption as to its origin.

In this case, you will have to inspect the flowers, which differ from Poaceae in being clustered into spikelets that lack lemmas and paleas (and the spikelets are mostly with spirally arranged flowers, which is never the case for grasses).
Also, the perianth may be present in the form of barbed bristles (something unique to Cyperaceae, even if not found in all genera of the family).
The spikerushes are distinguished from other genera in Cyperaceae by perfect flowers, a perianth of bristles, and most importantly by an achene with a thickened persistent style base, and an inflorescence of a single terminal

 Cyperaceae
A large, cosmopolitan family of mostly herbaceous plants, Cyperaceae occur primarily in moist temperate to wet tropical regions of the world; several species are of economic importance.
Because the spikelet is very small and the inflorescence structure very complex, interpretation is difficult and there is still controversy over recognition of subfamilies, tribes and genera.Molecular studies in the family are still in the early stages and have not, as yet, yielded any real solution to the problem.
There is controversy at higher levels too, so that sometimes Cyperaceae are included in the Order Poales and sometimes in their own order Cyperales.

Sheathing leaf bases of the Cyperaceae are also often 'closed' or firmly connected to the culm.
Clusters of florets, known as 'spikelets' for both families, are not subtended by pairs of 'sterile' bracts (glumes) in the Cyperaceae and some genera of the family show a perianth that is modified to form a series of bristles or scales.
The fruit is single-seeded, often a triangular or lenticular (lens shaped) achene or nutlet that, is some genera, carries features that are essential for identification to both genus and species.

 Cyperaceae | Mohlenbrock
The first in a series of four illustrated guides to identifying aquatic and standing water plants in the central Midwest, this convenient reference volume covers the 183 species of Cyperaceae.
Mohlenbrock provides descriptions, illustrations, and ways to identify any plant in the sedge family (Cyperaceae) in the states of Kentucky (except for the Cumberland region), Ohio, Indiana, Illinois, Iowa, Missouri, Kansas, and Nebraska.
Cyperaceae is a useful standard reference for state and federal employees who deal with aquatic and wetland plants and environmental conservation and mitigation issues and an essential guide for students and instructors in college and university courses where the identification of aquatic and wetland plants is emphasized.

 Cyperaceae (Sedge Family)
"Sedges have edges." The rule to remember in identifying members of Cyperaceae - and although those edges are sometime pretty subtle, it holds true for our native species.
They all grow in wet areas, if not right in creeks and ponds, which is another clue.
Bulrush will always be growing in or right next to water and has a series of stems coming up from underground stems- Pampas doesn't like to get its feet wet and grows from a central ball root system.
