parietales

Parietales include many flowering plants like violets and passionflowers.

Definition

Noun: 1. A taxonomic order of plants: "Parietales" is the name of a large, historical order of dicotyledonous flowering plants within the subclass Dilleniidae. This order is characterized by having parietal placentation, where the ovules are attached to the wall of the ovary.

Usage Notes
  • Scientific/Historical Term: The term "Parietales" is primarily used in botanical taxonomy and historical classification systems. In modern taxonomic revisions (e.g., the Angiosperm Phylogeny Group system), many families once grouped under Parietales have been reclassified into other orders.
  • Key Characteristic: The defining feature of plants in this order is parietal placentation. This is a botanical term describing how seeds are attached inside the fruit.
Examples
  • Noun:
    • The botanical text described the Parietales as a key order within the Dilleniidae.
    • Many species with parietal placentation were traditionally classified under Parietales.
Advanced Usage
  • In Taxonomic Context: The term is used when discussing the evolutionary history and historical classification of plant families such as Violaceae (violet family), Cucurbitaceae (gourd family), and Begoniaceae (begonia family), which were once placed here.
    • The family Violaceae was a core component of the now largely obsolete order Parietales.
Variants and Related Words
  • Parietal (adj): The adjective form, meaning "of or relating to the wall of a body part, cavity, or structure." In botany, it specifically refers to placentation on the ovary wall.
    • The parietal placentation is evident in the cross-section of the ovary.
Synonyms
  • Violales: In some modern taxonomic systems, the name Violales has been used for a similar, revised order encompassing many former Parietales families. However, they are not perfect synonyms due to differing circumscriptions.
Different Meanings
  • Not to be confused with: The term "parietal" alone, which is a much more common adjective. In general English, "parietal" often refers to the parietal bones of the skull or parietal lobes of the brain. In botany, it retains its specific meaning related to ovary walls. "Parietales" is the proper noun form of this botanical concept.
