subclass liliidae
Noun: - A taxonomic subclass of monocotyledonous flowering plants: Subclass Liliidae is one of four major groups within the class Monocotyledones (monocots). It is a botanical classification rank that encompasses a significant number of families characterized by specific morphological features, particularly their floral structures.
The term is used in scientific, botanical, and taxonomic contexts to classify and discuss a specific group of plants. - The subclass Liliidae includes many familiar ornamental and horticultural plants.
- Scientific Classification:
- Botanists place the orchid family within the subclass Liliidae.
- The phylogenetic study confirmed the placement of these species in the subclass Liliidae.
- In modern phylogenetic systems (like the APG system), the traditional rank of "subclass" is often replaced. The groups within Liliidae are frequently referred to as an "order" (Liliales) or a broader clade. However, "subclass Liliidae" remains a valid term in certain taxonomic frameworks.
- While the classic taxonomy uses subclass Liliidae, contemporary phylogeny often groups these plants under the order Asparagales.
- Liliidae: Often used synonymously with "subclass Liliidae."
- Monocotyledones: The larger class to which this subclass belongs.
- Liliales: An order of flowering plants that falls within this subclass in many classification systems.
- Liliid monocots: A more descriptive, informal synonym used in botanical literature.
The core meaning is taxonomic. It does not describe a physical object but a conceptual group in the biological classification hierarchy. Its members share common evolutionary ancestry and key characteristics.
-
one of four subclasses or superorders of Monocotyledones; comprises 17 families including: Liliaceae; Alliaceae; Amaryllidaceae; Iridaceae; Orchidaceae; Trilliaceae
