Class Dicotyledonae (Noun)
Meaning
Comprising seed plants that produce an embryo with paired cotyledons and net-veined leaves; divided into six (not always well distinguished) subclasses (or superorders): Magnoliidae and Hamamelidae (considered primitive); Caryophyllidae (an early and distinctive offshoot); and three more or less advanced groups: Dilleniidae; Rosidae; Asteridae.
Classification
Nouns denoting plants.
Examples
- The botanical classification system categorizes flowering plants into the class Dicotyledonae, which encompasses plants with paired cotyledons in their seeds.
- Botanists have traditionally divided the seed plants producing an embryo with paired cotyledons into the class Dicotyledonae.
- The class Dicotyledonae contains six major subclasses, including Magnoliidae, which is often considered the most primitive of the six.
- The subclasses within the class Dicotyledonae include Caryophyllidae, Dilleniidae, Rosidae, and Asteridae, all with distinct characteristics and evolutionary paths.
- Experts in botany differentiate between various subclasses in the class Dicotyledonae and have placed Hamamelidae among the more primitive subclasses of seed-producing plants.
