Definition

Proper noun * Liliaceae: A large family of monocotyledonous plants, commonly known as the lily family. It is characterized by flowers with parts typically in multiples of three, six showy tepals (often undifferentiated petals and sepals), six stamens, and a superior ovary. Many members grow from bulbs, corms, or rhizomes. Historically, this family was very broadly defined, encompassing many plants now classified into separate families.

Usage
  • The term Liliaceae is used as a taxonomic family name in botany. It is always capitalized and typically used in singular form with a singular or plural verb, depending on context.
  • Example: "Liliaceae is a family of great horticultural importance." (Singular verb)
  • Example: "The Liliaceae include many popular garden flowers." (Plural verb)
Examples
  • Botanists have reclassified several genera formerly placed in the Liliaceae.
  • Tulips and true lilies are classic representatives of the Liliaceae.
  • The phylogenetic study aimed to clarify the relationships within the Liliaceae.
Advanced Usage
  • In modern taxonomic systems (e.g., APG IV), the circumscription of Liliaceae is much narrower than in traditional classifications. Many plants once considered part of this family are now placed in other families like Asparagaceae, Amaryllidaceae, and Melanthiaceae.
  • The phrase "in the broad sense" or is sometimes used to refer to the traditional, broad definition of Liliaceae, while "in the narrow sense" or refers to the modern, more restricted definition.
Variants and Related Words
  • Liliaceous (adjective): Of or relating to the lily family (Liliaceae).
    • Example: "The plant has the liliaceous characteristic of parallel leaf venation."
Synonyms
  • Lily family (the common name).
  • (Historically, in a broad sense) A grouping that included many now-separate families such as Alliaceae, Asparagaceae, and Hyacinthaceae.
Notes on Different Meanings
  • The primary and only meaning of Liliaceae is as a botanical taxonomic rank (family). It does not have idiomatic or non-scientific meanings. Its definition has evolved significantly from a large, "catch-all" family to a more precisely defined one based on genetic evidence.
