• In formal writing, the word "order" is often included for clarity (e.g., "the order Dicranales"), but the taxonomic name itself is "Dicranales".

Examples

• Scientific Context:
  • The moss specimen was definitively classified within the order Dicranales.
  • Dicranales is one of the most diverse orders of mosses, containing numerous families.
  • Researchers are studying the evolutionary relationships within the Dicranales.

Advanced Usage

• In detailed botanical descriptions, the defining characteristics are often listed:
  • The order Dicranales is diagnosed by its erect gametophores, peristome teeth that are often split or perforated, and capsules that are usually cylindrical and erect.
