Rhytidiadelphus (order Hypnobryales) A genus of large, robust mosses in which the shoots are erect to procumbent. The stems are usually long, and irregularly to pinnately branched. The leaves are broad at the base, gradually or abruptly narrowing to a sharply pointed tip; each leaf may have a short double nerve, or it may be nerveless. The seta is deep red and smooth. There are about 8 species, mainly found in northern temperate regions, and including some attractive British species. R. triquetrus is often conspicuous, with tall, tough, erect stems from which branches arise irregularly to give a bushy habit; the leaves are large and spreading, and capsules are rarely formed. It is found mostly in woodland clearings. R. squarrosus is a smaller moss with squarrose leaves; the shoot apices have a characteristic star-like appearance. It is found in moist grassland and is a common weed in lawns.

Citation styles 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, cannot guarantee each citation it generates. Therefore, it’s best to use 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:

  • Most online reference entries and articles do not have page numbers. Therefore, that information is unavailable for most 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.
