tigernut, nearly cosmopolitan perennial (Cyperus esculentum) of the family Cyperaceae (sedge family) of the same genus as the papyrus plant. The tigernut has been cultivated since early times (chiefly in S Europe and W Africa) for its small, tuberous rhizomes, which are eaten raw or roasted, used for hog feed, and pressed for the juice to make a beverage. A nondrying oil (usually called chufa) is also obtained from the rhizome. In W Africa the plant often grows in great concentration and is gathered from the wild. In the S United States it is sometimes a troublesome weed in planted fields. Other names are earth almond and yellow nut grass. The tigernut is classified in the division Magnoliophyta, class Liliopsida, order Cyperales, family Cyperaceae.

Encyclopedia.com gives you the ability to cite reference entries and articles according to common styles from the Modern Language Association (MLA), The Chicago Manual of Style, and the American Psychological Association (APA).
Within the “Cite this article” tool, pick a style to see how all available information looks when formatted according to that style. Then, copy and paste the text into your bibliography or works cited list.
Because each style has its own formatting nuances that evolve over time and not all information is available for every reference entry or article, Encyclopedia.com cannot guarantee each citation it generates. Therefore, it’s best to use Encyclopedia.com citations as a starting point before checking the style against your school or publication’s requirements and the most-recent information available at these sites:
Modern Language Association
The Chicago Manual of Style

- Most online reference entries and articles do not have page numbers. Therefore, that information is unavailable for most Encyclopedia.com content. However, the date of retrieval is often important. Refer to each style’s convention regarding the best way to format page numbers and retrieval dates.
- In addition to the MLA, Chicago, and APA styles, your school, university, publication, or institution may have its own requirements for citations. Therefore, be sure to refer to those guidelines when editing your bibliography or works cited list.
