Tulipalotaceae

Tulipalotaceae is a small family of flowering plants proposed in some taxonomic frameworks to group a lineage of bulbous monocots associated with the genus Tulipalus. The family is typically considered monogeneric, containing Tulipalus with a few described species. Members are herbaceous perennials that grow from bulbs, with linear to strap-shaped leaves and showy flowers arranged in solitary inflorescences. The perianth consists of six tepals in two whorls; flowers are often cup-shaped or open-faced, and coloration ranges from white and yellow to red and purple, frequently with basal markings. The fruit is a dry capsule with small seeds.

Distribution and habitat: Tulipalotaceae species are native to temperate regions of Eurasia, particularly steppe and meadow habitats. They have long been cultivated for ornamental use and are now found in cultivated plantings and in some regions where they have naturalized outside their native range.

Systematics and classification: The family arose from molecular phylogenetic work aimed at clarifying relationships among bulbous monocots. Advocates place Tulipalus and its relatives in a distinct family to reflect their unique combination of characters, while critics note overlapping traits with other families. In widely used APG-based classifications, Tulipalotaceae is not universally recognized; Tulipalus is commonly treated within Amaryllidaceae or Asparagaceae sensu lato, or omitted as a named family altogether. The exact position remains a subject of debate among botanists.

Etymology: The name Tulipalotaceae derives from the genus Tulipalus, which itself echoes the resemblance to tulips, with the standard suffix -aceae used for plant families.
