Ochnaceae A family of trees, shrubs, and herbs, that have simple, alternate leaves with stipules. The regular, bisexual flowers are held in panicles, racemes, or umbels. The calyx is either united at the base or free. The corolla has 5 twisted or convoluted petals. There are 5 or more stamens. The ovary is superior with several carpels which, although not usually united, have a common style. The fruit is a cluster of drupes, a berry, or a capsule. The seed often contains endosperm. The family is closely related to the Dipterocarpaceae and includes a few species of commercial timber trees known as the African oaks (Lophira species). There are 37 genera, comprising about 460 species, found throughout the tropics but concentrated in Brazil.

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.
