Usage

Examples

• Adjective:
  • The mint family is known for its two-lipped flowers.
  • A two-lipped calyx is a distinguishing feature of some plant species.

Advanced Usage

• Technical Description: In botany, "two-lipped" (synonymous with ) precisely describes a corolla or calyx where the petals or sepals are fused into an upper and a lower section, creating an open mouth-like shape.
  • The botanist noted the two-lipped corolla, which is perfect for pollination by bees.

Variants and Related Words

  • The bilabiate flowers of the snapdragon are a classic example.

Synonyms

• Actinomorphic: A technical term for radially symmetrical flowers.

Notes

• The term is highly specific. In non-scientific contexts, describing something as "two-lipped" would be unusual and potentially confusing. The common word "lipped" is typically used without a number (e.g., "thin-lipped").
• It is a compound adjective formed from "two" and "lipped." The hyphen is essential when it precedes a noun (e.g., "a two-lipped flower") but may be omitted in predicate position (e.g., "The flower is two lipped"), though the hyphenated form is generally preferred for clarity.
