family Hemerocallidaceae
Noun A taxonomic family name used in some botanical classification systems. It refers to a group of flowering plants, primarily the daylilies, which are placed within this family by certain systems. This classification is not universally accepted, as many modern systems include these plants within the broader family Asphodelaceae or formerly within Liliaceae.
The term is used in specialized botanical contexts to describe a specific taxonomic grouping. * In some older classifications, plants like the common daylily were placed in family Hemerocallidaceae. * The Hemerocallidaceae family, as proposed, is characterized by its rhizomatous growth and showy flowers.
- Taxonomic Debate: The term's primary advanced usage lies in discussions of plant taxonomy and systematics, highlighting the historical and ongoing debate over how to correctly classify related genera like (daylilies).
- Hemerocallidaceae: This is the standard form of the family name.

- (Historical context) Part of Liliaceae sensu lato: In very broad, older classifications, these plants were sometimes included in the lily family, Liliaceae.
This term has a single, precise meaning within scientific nomenclature. Its usage reflects a specific, non-dominant viewpoint in botanical taxonomy. It is not used in everyday language.
