Goeppertia veitchiana 'Medallion Veitchiana'

Goeppertia veitchiana (Veitch ex Hook.f.) Borchs. & S.Suárez is the accepted species name for the plant that circulates in trade as 'Medallion Calathea' or 'Medallion Prayer Plant'. Plants of the World Online, maintained by the Royal Botanic Gardens, Kew, records the accepted name and places the species within the family Marantaceae [1]. The North Carolina State University Extension Gardener Plant Toolbox describes the species as a clumping, slow-growing herbaceous perennial native to the rainforests of Ecuador, reaching 1 to 2 feet in height and width, noting that it rarely produces flowers in cultivation [3].

The cultivar epithet recorded in this registry is 'Medallion Veitchiana'. The registry holds this as nomenclatural evidence pending source verification, and the epithet is not independently citable in prose from a primary registration record. No formal cultivar description meeting the requirements of the International Code of Nomenclature for Cultivated Plants has been located in any registration record, patent document, or peer-reviewed source.

Registered epithet. The epithet 'Medallion Veitchiana' is held in this registry as the cultivar epithet. No cultivar register for Marantaceae or the genus Goeppertia exists against which this epithet could be verified or assigned a registration number. No International Cultivar Registration Authority has been appointed for Marantaceae; neither Marantaceae nor Goeppertia appears on the International Society for Horticultural Science list of appointed authorities [4].

Trade designation. The North Carolina State University Extension Gardener Plant Toolbox records the common names 'Calathea Medallion' and 'Medallion Prayer Plant' against Goeppertia veitchiana [3]. No trade designation distinct from the cultivar epithet has been documented in any primary record consulted for this entry.

Patent denomination. No patent denomination has been located. No search of USPTO records returned a primary patent document for this cultivar under any spelling or trade-name variant. The registry records no patent number for this cultivar, and no patent term or expiry applies.

Plants of the World Online lists four synonyms now subsumed under the 2012 combination: Calathea veitchiana Veitch ex Hook.f., Maranta veitchiana (Veitch ex Hook.f.) Van Houtte (1865), Phyllodes veitchiana (Veitch ex Hook.f.) Kuntze (1891), and Calathea veitchiana var. foxii Raffill (1914) [1].

No originator is documented. This cultivar predates any registration authority for Marantaceae.

The GBIF Backbone Taxonomy confirms the basionym Calathea veitchiana Veitch ex Hook.f. and records the first publication as Curtis's Botanical Magazine plate 5535 in 1865 [3], indicating the plant was received by or collected under the auspices of the Veitch nursery and described by Joseph Dalton Hooker. No plant patent, no breeder's rights certificate, and no dated nursery introduction record establishing a specific originator for the cultivar 'Medallion' or 'Medallion Veitchiana' has been located. No seed parentage or pollen parentage is documented. No year of establishment is documented.

Limited authoritative sources available; further research needed on the derivation and first introduction of this cultivar.

Borchsenius, Suárez and Prince published the combination Goeppertia veitchiana (Veitch ex Hook.f.) Borchs. & S.Suárez in 2012, in Systematic Botany 37(3): 635, as part of a molecular phylogenetic revision demonstrating that Calathea as previously circumscribed was polyphyletic [2]. That revision established 246 new combinations in Goeppertia. Plants of the World Online records the accepted name and lists the species as occurring in the wet tropical biome, with its native range confined to Ecuador [1].

The North Carolina State University Extension Gardener Plant Toolbox describes the leaves of Goeppertia veitchiana (Calathea Medallion) as rounded to oval, deep green with light green variegations, and with burgundy undersides [3]. The same source characterises the foliage as bearing feather markings of lime green and creamy white over the deep green ground colour, and documents the plant as reaching 1 to 2 feet in height and width [3].

No formal description of distinguishing traits specific to the cultivar epithet 'Medallion Veitchiana', as distinct from the species more broadly, has been located in any registration record, patent document, or peer-reviewed source. Limited authoritative sources available; further research needed on cultivar-specific trait documentation.

The primary taxonomic record for this cultivar's parent species rests on two sources: the Plants of the World Online entry maintained by the Royal Botanic Gardens, Kew, which records the accepted name, synonymy, and native range [1]; and the 2012 revision by Borchsenius, Suárez and Prince in Systematic Botany, which published the transfer from Calathea to Goeppertia [2]. The North Carolina State University Extension Gardener Plant Toolbox provides the only located authoritative source documenting the cultivar name 'Medallion' alongside species-level leaf characters and cultivation notes [3].

No originator is documented. This cultivar predates any registration authority for Marantaceae. No patent denomination has been located. No registration number exists, as no International Cultivar Registration Authority has been appointed for Marantaceae [4]. The registry records verified_against_primary as false for this cultivar entry.

Limited authoritative sources available; further research needed on the formal circumscription of the cultivar epithet, the history of its introduction into trade, and any proprietary rights that may or may not have been sought in any jurisdiction.
