Overview
The cultivar name 'Silver Plate' is applied, in trade use, to a selection of Goeppertia bachemiana (É.Morren) Borchs. & S.Suárez, a species in the family Marantaceae. Plants of the World Online records the accepted name with IPNI identifier urn:lsid:ipni.org:names:60458927-2, and records the native range as Brazil (Rio de Janeiro) in the wet tropical biome [2].
The parent species was originally described by Édouard Morren under the basionym Calathea bachemiana É.Morren. The combination transferring the species into Goeppertia Nees was published by Borchsenius, Suárez and Prince in 2012, as part of a molecular revision of Marantaceae that produced 246 new combinations moving species from Calathea G.Mey. into Goeppertia, after demonstrating that Calathea as previously circumscribed was polyphyletic [3]. Plants of the World Online records Calathea bachemiana É.Morren as a synonym of the accepted name [2].
No formal diagnostic description of the cultivar 'Silver Plate' has been located in any peer-reviewed source, plant patent, or registration authority record. Limited authoritative sources available; further research needed.
Names and Name Classes
The International Code of Nomenclature for Cultivated Plants (ICNCP) requires that a cultivar epithet be enclosed in single quotation marks and not italicised [1]. The correct rendering is therefore 'Silver Plate', not Silver Plate and not Silver Plate without marks.
Registered epithet: 'Silver Plate' is recorded in the Digital Towns registry as a cultivar epithet applied to Goeppertia bachemiana. Because no International Cultivar Registration Authority has been appointed for Marantaceae [1], the epithet has not been registered against any formal cultivar register and cannot be confirmed as unique under ICNCP provisions.
Trade designation: No trade designation distinct from the cultivar epithet 'Silver Plate' has been located in any primary record consulted. No separate marketing name or trademark has been identified.
Patent denomination: No plant patent denomination has been located for this selection. The registry field patent_number is null. Limited authoritative sources available; further research needed.
Origin and Authorship
No originator is documented. This cultivar predates any registration authority for Marantaceae.
The registry records the originator field as null and sets originator_unknown to true. No plant patent naming an inventor for this selection has been located in USPTO records. No registration record at any cultivar registration authority has been located, as no International Cultivar Registration Authority has been appointed for Marantaceae [1]. No dated record establishing a first use of the name 'Silver Plate' with a named originator has been located in the course of this research pass.
The year of establishment, place of origin, parentage (seed parent and pollen parent), and derivation are all undocumented. Limited authoritative sources available; further research needed.
Registration Context
No International Cultivar Registration Authority has been appointed for Marantaceae. The Commission Cultivar Registration of the International Society for Horticultural Science (ISHS) is responsible for appointing ICRAs and monitoring their work; no appointment covering Marantaceae or its constituent genera, including Goeppertia Nees, appears in the ISHS commission listings [1].
The Aroid Cultivar Registry records the International Aroid Society as the ICRA for Araceae, with the exception of the genera Calla L. and Zantedeschia Spreng. [5]. Marantaceae is a distinct family in the order Zingiberales and falls outside that denomination class.
In the absence of an appointed ICRA, there is no formal register against which 'Silver Plate' can be checked for name uniqueness under ICNCP provisions. Digital Towns is an applicant and an aggregator; it is not affiliated with, endorsed by, or accredited by ISHS or any appointed ICRA.
Documentation
The taxonomic foundation for this page rests on two primary records. Plants of the World Online provides the accepted name, IPNI identifier, basionym, native range and habit for the parent species [2]. The 2012 paper by Borchsenius, Suárez and Prince in Systematic Botany 37(3): 620-635 provides the published authority for the transfer of this species from Calathea into Goeppertia and for the broader circumscription of the genus [3].
No primary record documenting the cultivar 'Silver Plate' specifically has been located: no plant patent, no registration authority entry, no protologue, and no peer-reviewed cultivar description. The Digital Towns registry entry for this cultivar is based on trade-use nomenclatural evidence only. Limited authoritative sources available; further research needed.
