Definition

Noun 1. A botanical order of plants: "Ranales" is the name of a taxonomic order of flowering plants, historically used in some classification systems. It primarily includes families characterized by often having numerous, separate floral parts (like many stamens and carpels) and considered to be among the more primitive groups of dicotyledonous plants.

Usage Notes
  • "Ranales" is a specialized term used in botanical taxonomy and scientific literature. It is not used in everyday conversation.
  • In modern phylogenetic classifications (APG system), the families once grouped under "Ranales" are now distributed among several orders, such as Ranunculales, Magnoliales, Laurales, and others. Therefore, the term "Ranales" is considered largely historical or traditional in contemporary botany.
Examples
  • Scientific Context:
    • The order Ranales encompasses plants with apocarpous gynoecia.
    • Early taxonomic systems placed the buttercup and magnolia families within the Ranales.
Advanced Usage
  • The name "Ranales" is derived from the type family (the buttercup family), with the suffix denoting an order.
  • Discussions on plant evolution often reference the "ranalean complex" when describing ancestral floral traits.
Variants and Related Words
  • Ranalean (adjective): Pertaining to or characteristic of the order Ranales.
    • The flower exhibits a ranalean structure with spirally arranged parts.
  • Ranunculales (noun): The modern order that includes the Ranunculaceae and several other families formerly in Ranales.
Synonyms
  • Buttercup order (an informal, descriptive synonym based on a key family).
  • Polycarpicae (an older, alternative name for a similar grouping of plants with multiple carpels).
Related Terms (Contextual)
  • Magnoliids: A major clade of flowering plants in modern systems that includes orders like Magnoliales and Laurales, containing many families from the traditional Ranales.
  • Primitive angiosperms: A descriptive term for plant groups, including those once in Ranales, that retain ancestral characteristics.
Noun
  1. herbs, shrubs and trees: includes families Ranunculaceae; Annonaceae; Berberidaceae; Magnoliaceae; Menispermaceae; Myristicaceae; Nymphaeaceae; Lardizabalaceae; Lauraceae; Calycanthaceae; Ceratophyllaceae; Cercidiphyllaceae
