- It refers to a proposed grouping that is considered a subfamily within the larger lily family (Liliaceae) in certain systems.
Examples
- Scientific Discussion:
- Some older classification systems placed the daylilies in the Hemerocallidaceae.
- The status of Hemerocallidaceae as a distinct subfamily is debated among taxonomists.
Advanced Usage
- In Taxonomic Literature: The term appears in botanical texts and research papers that compare different phylogenetic systems. Its usage often comes with a qualifier, such as "sometimes included in" or "not widely accepted."
- The genus Hemerocallis is sometimes segregated into the Hemerocallidaceae.
Variants and Related Words
- Hemerocallis (n): The principal genus within the proposed Hemerocallidaceae subfamily, commonly known as daylilies.
