Parnassiaceae
family of plants
Parnassiaceae Gray were a family of flowering plants in the eudicot order Celastrales. The family is not recognized in the APG III system of plant classification. When that system was published in 2009, Parnassiaceae were treated as subfamily Parnassioideae of an expanded family Celastraceae.
The family had only two genera, Lepuropetalon and Parnassia. Lepuropetalon has only one species, Lepuropetalon spathulatum, a winter annual that usually prefers sandy soil. It is one of the smallest of flowering plants, up to 2 cm tall. Lepuropetalon has a disjunct distribution, being known from the southeastern United States and central Chile, but is probably far more common than has been reported.
Parnassia is a genus of perennial herbs, up to 60 cm tall, that grow in bogs, marshes, and other wet areas, mostly in cool to cold climates of the north temperate zone. There are at least 70 species. Sixty-three species occur in China and 49 of these occur nowhere else.
This brief starts where responsible research should: with the source description of “Parnassiaceae” as family of plants. Everything that follows is an evidence route, not borrowed authority.
Why this record matters
The subject matters to the general reference register because the source frames it as family of plants. Its deeper value depends on whether names, dates, institutions and citations support that framing.
Named sources, stable identifiers and responsible institutions provide the strongest route from overview to verifiable evidence. The source revision retrieved here is dated May 17, 2026. The linked authority identifier is Q162149. None of the 0 selected statements returned an explicit reference. The first chronological checks are 2009.
Overview language is designed for orientation and should not be treated as a substitute for the evidence cited beneath it. The lead is largely declarative, so disagreement and counter-evidence require a deliberate search beyond the opening account. Authority statements aid reconciliation but still require their own references, qualifiers and ranks to be checked.
