Marianthus
genus of plants
Marianthus is a genus of flowering plants in the family Pittosporaceae and is endemic to Australia. Plants in the genus Marianthus are shrubs with twining branches, simple leaves arranged alternately along the stems. The flowers are pendent, arranged singly or in small groups in upper leaf axils or on the ends of branches with small bracts and bracteoles at the base, but that fall as the flowers open. The sepals are free from each other, and the petals are also sometimes free from each, otherwise joined at the base, forming a tube with spreading lobes. Plants in this genus were previously included in Billardiera, but have a stalked ovary and a long, usually curved style. The fruit is a dehiscent capsule containing many seeds.
The genus Marianthus was first originally established in 1837 by Stephan Endlicher in his Enumeratio plantarum quas in Novae Hollandiae ora austro-occidentali ad fluvium Cygnorum et in sinu Regis Georgii collegit Carolus Liber Baro de Hügel, and the first species he described (the type species) was M. candidus. In 1972, Eleanor Marion Bennett combined the genera Billardiera and Marianthus in Billardiera, in the journal Nuytsia, so that Marianthus became a synonym of Billardiera. The name Marianthus means "Virgin Mary-flower", on account of the white colour of M. candidus, the first species in the genus to be described.
In 2004, Marianthus was resurrected from synonymy by Lindy Cayzer and Mike Crisp in the journal Australian Systematic Botany, and the name is accepted by the Australian Plant Census.
This brief starts where responsible research should: with the source description of “Marianthus” as genus of plants. Everything that follows is an evidence route, not borrowed authority.
Why this record matters
The subject matters to the science & nature register because the source frames it as genus of plants. Its deeper value depends on whether names, dates, institutions and citations support that framing.
Datasets, specimens, observations and peer-reviewed methods provide the appropriate test for the technical claims summarized here. The source revision retrieved here is dated Jul 30, 2024. The linked authority identifier is Q6762441. None of the 0 selected statements returned an explicit reference. The first chronological checks are 1837, 1972 and 2004.
Current terminology should not be projected backward without checking the classification used when the underlying evidence was created. 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.
How to read it
Check terminology, classification and the date of the cited evidence. Scientific names and technical consensus can change while older records retain historical value.

Primary datasets, specimen catalogues, standards bodies and the most recent peer-reviewed literature.
Three-step research path
- Establish the record: confirm the title “Marianthus”, its source revision and the description used here.
- Expand the search: follow Marianthus primary sources, Marianthus archive and Marianthus research across catalogues and specialist indexes.
- Test the account: compare the strongest cited source with the responsible institution’s current record and note any disagreement.
