Racomitrium

Racomitrium (order Grimmiales) A genus of medium to large mosses, in which the archegonia (and hence capsules) are borne terminally on short, lateral branches. Stems are erect or prostrate, often with numerous short branches. It is a cosmopolitan genus, with about 80 species. Most are saxicolous, mainly on acidic rocks. R. aciculare grows on acidic rocks near or in water. R. aquaticum grows mainly on wet acidic rocks and on ledges in mountainous regions, often near flowing water. R. lanuginosum grows on exposed mountain tops on rock or on peat, often forming extensive mats and giving its name to the plant community of this habitat: Racomitrium heath (formerly Rhacomitrium heath). In this species each leaf has a long hair point (often as long as the leaf itself), which is rough with minute teeth; the plant has a characteristic grey-green colour, and the shoots appear hoary because of the massed, white hair points.

Citation styles

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:

Notes:
  • 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.
