caryophyllidae
A botanist carefully examines a pink carnation from the caryophyllidae group.
Noun: 1. A taxonomic subclass: In some botanical classification systems, 'Caryophyllidae' refers to a subclass of flowering plants (dicotyledons). This group is characterized by specific botanical features, most notably flowers with a central or basal arrangement of ovules (placentation) and pollen grains containing three nuclei when shed (trinucleate pollen). 2. An approximate taxonomic order: The group corresponds roughly to the order Caryophyllales in modern classification systems. It encompasses families of plants that often exhibit adaptations to arid or harsh conditions.
- Noun:
- The botanist studied the unique floral structures within the Caryophyllidae.
- Plants classified under Caryophyllidae often have trinucleate pollen, which is less common among angiosperms.
- The classification of Caryophyllidae includes families like the Cactaceae (cacti) and Amaranthaceae.
- Taxonomic Context: The term 'Caryophyllidae' is primarily used in the context of formal botanical taxonomy and scientific literature. It represents a specific rank (subclass) in the hierarchical biological classification system.
- Historical Classification: Note that 'Caryophyllidae' as a subclass is part of older classification schemes. In contemporary systems (e.g., the APG system), the group of plants is more commonly referred to as the order Caryophyllales.
- Caryophyllales (n): The corresponding order name in modern phylogenetic classifications, encompassing the same core group of plant families.
- caryophyllaceous (adj): Of or relating to the family Caryophyllaceae (the pink or carnation family), which is a central family within this group.
- Subclass Caryophyllidae: The full taxonomic designation.
- (Roughly) Order Caryophyllales: The modern equivalent grouping.
The meaning of 'Caryophyllidae' is highly specific to botanical science. Its primary definition is taxonomic, referring to a formal category in the classification of life. It does not have everyday, metaphorical, or idiomatic uses outside of scientific discourse. The key distinguishing feature highlighted in its definition is the trinucleate pollen, a technical characteristic that differentiates it from many other flowering plants.
A botanist carefully examines a pink carnation from the caryophyllidae group.
- 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
