subclass Caryophyllidae
Noun: A taxonomic subclass of flowering plants (angiosperms) characterized by having basal or central placentation (the arrangement of ovules within the ovary) and trinucleate pollen (pollen grains containing three nuclei when shed, whereas binucleate pollen is more common in other flowering plants). This group contains approximately 14 families and corresponds roughly to the order Caryophyllales.
The term is used in botanical taxonomy and scientific classification to refer to this specific group of dicotyledonous plants. * In modern classification systems, the group Caryophyllidae is often treated as an order (Caryophyllales) rather than a subclass. * The subclass Caryophyllidae includes many families adapted to arid environments.
- The classification rank of this group (subclass, superorder, or order) has varied between different taxonomic systems, reflecting evolving scientific understanding.
- Caryophyllales (n): The corresponding order in many modern taxonomic systems, essentially synonymous with the subclass Caryophyllidae.
- caryophyllaceous (adj): Of or relating to the family Caryophyllaceae or the larger group Caryophyllidae.
- Caryophyllales (when referring to the order)
- The pink or carnation subclass (descriptive synonym)
This is a specialized scientific term with a single, precise meaning in plant taxonomy. Its usage is almost entirely confined to academic and botanical contexts.
- a group of families of mostly flowers having basal or central placentation and trinucleate pollen (binucleate pollen is commoner in flowering plants); contains 14 families including: Caryophyllaceae (carnations and pinks); Aizoaceae; Amaranthaceae; Batidaceae; Chenopodiaceae; Cactaceae (order Opuntiales); Nyctaginaceae; Phytolaccaceae; corresponds approximately to order Caryophyllales; sometimes classified as a superorder
