cymose

Thân thiện

The botanist points out a cymose inflorescence on the plant specimen.

Definition

Adjective (Botany): 1. Describing a type of flower cluster (an inflorescence) in which the main stem and each branch end in a single flower. The terminal flower opens first, and subsequent flowers develop from lateral buds below it. This pattern results in a growth that is often flat or convex at the top, rather than continuing to grow from a central tip.

Usage

• The term cymose is a technical adjective used almost exclusively in botany to classify and describe the structure of a plant's inflorescence.
• It is typically used before a noun (e.g., a cymose inflorescence) or in the predicate (e.g., "The inflorescence is cymose.").

Examples

• The geranium plant exhibits a cymose pattern of flowering.
• Botanists identified the species by its characteristic cymose clusters.
• In a cymose inflorescence, the oldest flower is positioned at the apex.

Advanced Usage

• Cymose is the overarching term for several specific types of determinate inflorescences, including:
  • Dichasium: A cyme where each flowering stem produces two lateral branches.
  • Monochasium: A cyme where each flowering stem produces only one lateral branch.
• The concept is often contrasted with racemose inflorescences, which have indefinite growth from a central tip, with the youngest flowers at the apex.

Variants and Related Words

• Cyme (noun): The flower cluster itself that has a cymose structure.
  • The plant bore a simple dichasial cyme.
• Cymosely (adverb): In a cymose manner.
  • The branches were arranged cymosely.

Synonyms

• Determinate (inflorescence)
• Definite (inflorescence)

Antonyms

• Racemose (having an indeterminate inflorescence where the main axis continues to grow)
• Indeterminate (inflorescence)
