Goeppertia chimboracensis

Goeppertia chimboracensis (Linden) Borchs. & S.Suárez is an accepted species in the genus Goeppertia Nees, family Marantaceae. Plants of the World Online, maintained by the Royal Botanic Gardens, Kew, records it as a perennial herb growing primarily in the wet tropical biome, with a native range restricted to Ecuador [1]. The GBIF Backbone Taxonomy (dataset d7dddbf4-2cf0-4f39-9b2a-bb099caae36c) records the species at GBIF key 9355492 and corroborates the accepted name with its full authority [4].

The genus Goeppertia is documented by the registry as the accepted botanical name for the largest genus in Marantaceae, encompassing an estimated 260 species. The great majority of those species were transferred from Calathea G.Mey. by Borchsenius, Suárez and Prince in 2012 after a molecular phylogenetic study demonstrated that Calathea as previously circumscribed was polyphyletic [2]. Goeppertia chimboracensis is one of those transferred species; it has circulated in the horticultural trade under the synonym names Calathea chimboracensis and Calathea lehmannii, neither of which is the accepted name under current botanical nomenclature.

The IUCN Red List of Threatened Species assessed the species in 2004 — under the name then applied, Calathea chimboracensis — as Endangered under criteria A4c, describing it as a terrestrial herb endemic to coastal Ecuador known at the time of assessment from five localities, none of which fell within the protected areas network [3]. Habitat destruction was identified as the primary documented threat [3]. A note on registry conflicts: the registry native_range and habitat fields are recorded as null, whereas Plants of the World Online supplies Ecuador as the native range and documents the wet tropical biome as the growth context [1]; and the IUCN Red List supplies habitat characterisation for coastal Ecuador [3]. These discrepancies are flagged for a human reviewer to resolve by updating the registry fields.

The nomenclatural chain for this taxon begins with Jean Linden, the Belgian horticulturist and plant collector, who published the basionym Maranta chimboracensis in his Catalogue des Plantes Exotiques 22/23: 6 in 1869 [1]. The epithet chimboracensis is a toponym referring to the Chimborazo region of Ecuador, consistent with the species' documented native range in that country [1][3]. Linden himself subsequently transferred the epithet into Calathea, publishing Calathea chimboracensis (Linden) Linden in L'Illustration Horticole 17: t. 6 in 1870 [1]. A further transfer into Phyllodes was made by Kuntze, who published Phyllodes chimboracensis (Linden) Kuntze in Revisiones Generum Plantarum 2: 696 in 1891; that combination is now treated as a synonym of the accepted name [1].

An independently described synonym, Calathea lehmannii K.Schum., was published by K. Schumann in H.G.A. Engler (ed.), Das Pflanzenreich IV, 48: 78 in 1902 [1]. This name represents the same taxon and is listed as a resolved synonym under the accepted combination in Plants of the World Online [1] and confirmed by Borchsenius, Suárez and Prince in their 2012 revision [2]. A registry conflict is noted: the registry name row for Calathea lehmannii omits the author K.Schum. and the publication citation; Plants of the World Online supplies the full authority as Calathea lehmannii K.Schum. in H.G.A.Engler (ed.), Pflanzenr., IV, 48: 78 (1902) [1]. A human reviewer should update the registry name string accordingly.

The current accepted combination, Goeppertia chimboracensis (Linden) Borchs. & S.Suárez, was published by Borchsenius, Suárez and Prince in Systematic Botany 37(3): 629 in 2012, as part of the same revision that transferred 246 Calathea names to Goeppertia following the demonstration that Calathea as previously circumscribed was polyphyletic [2]. Plants of the World Online records the IPNI identifier for this combination as 60459185-2 [1]. A further registry conflict is noted: the registry ipni_id field is recorded as null, whereas Plants of the World Online supplies the identifier 60459185-2 [1]; this discrepancy is flagged for a human reviewer.

The four names that resolve as synonyms under the accepted combination, as recorded by Plants of the World Online [1], are:

• Maranta chimboracensis Linden (1869) — basionym
• Calathea chimboracensis (Linden) Linden (1870) — homonym entry treated as synonym per GBIF Backbone Taxonomy [4]
• Phyllodes chimboracensis (Linden) Kuntze (1891) — synonym
• Calathea lehmannii K.Schum. in H.G.A.Engler (ed.), Pflanzenr., IV, 48: 78 (1902) — synonym

Plants of the World Online characterises Goeppertia chimboracensis as a perennial herb growing primarily in the wet tropical biome [1]. The IUCN Red List assessment (2004) describes the species as a terrestrial herb endemic to coastal Ecuador [3]. No morphological diagnostic description from a primary taxonomic source — such as a protologue, monograph, or peer-reviewed revision — has been located beyond these growth-form and biome characterisations. The 2012 revision by Borchsenius, Suárez and Prince focussed on phylogenetic circumscription of the genus rather than species-level morphological diagnoses for each transferred combination [2]. Limited authoritative sources available; further research needed.

Plants of the World Online records the native range of Goeppertia chimboracensis as Ecuador, with the species growing primarily in the wet tropical biome [1]. The IUCN Red List of Threatened Species assessed the species in 2004 — under the then-current name Calathea chimboracensis — and assigned it the status Endangered under criteria A4c [3]. The IUCN assessment documents the species as a terrestrial herb endemic to coastal Ecuador, known at the time of assessment from five localities, and states explicitly that none of those localities were located inside the protected areas network [3]. Habitat destruction is identified in the assessment as the primary documented threat [3].

A 2024 extinction risk study, cited by Plants of the World Online in its conservation data for this species, predicted the extinction risk as threatened with confident classification [1]. No cultivation range data from a botanic garden or herbarium publication has been located; further research needed for that dimension. No plant patent exists for this species, and no plant variety protection record has been identified in the sources consulted.

The registry records Goeppertia chimboracensis as present in cultivation (in_cultivation: true). The species has circulated in the horticultural trade under the synonym names Calathea chimboracensis and Calathea lehmannii, both of which are now resolved as synonyms of the accepted name under the 2012 revision by Borchsenius, Suárez and Prince [2]. The IUCN Red List assessment (2004) acknowledges the taxon's presence in cultivation contexts without providing quantitative horticultural data; its primary concern is the status of wild populations in coastal Ecuador [3].

No botanic garden publication, university extension document, or peer-reviewed cultivation study has been located that documents the horticultural characteristics of this species from an authoritative source. Limited authoritative sources available; further research needed. No cultivars of Goeppertia chimboracensis are documented in this registry or in any source consulted.

No International Cultivar Registration Authority has been appointed for Marantaceae. The International Society for Horticultural Science maintains the list of appointed International Cultivar Registration Authorities by family; Marantaceae does not appear on that list [5]. The consequence for this species is that no formal cultivar register exists for any cultivar of Goeppertia chimboracensis, and no body currently holds the mandate to adjudicate cultivar epithets in this genus. The International Code of Nomenclature for Cultivated Plants (ICNCP) requires that a cultivar epithet be enclosed in single quotation marks and be distinct from all other cultivar epithets within the denomination class. The genus Goeppertia Nees falls within denomination class goeppertia as defined in this registry, but the absence of an appointed ICRA means no third-party registration authority currently governs that denomination class for any cultivar in the genus. No cultivars of Goeppertia chimboracensis are documented in the registry fact pack.
