Goeppertia angustifolia

Goeppertia angustifolia (Körn.) Borchs. & S.Suárez is an accepted species within Goeppertia Nees, the largest genus in the family Marantaceae. Plants of the World Online (POWO), maintained by the Royal Botanic Gardens, Kew, records this binomial as the accepted name and lists Calathea angustifolia Körn. as a synonym [1]. The GBIF Backbone Taxonomy independently accepts the same name under key 9366933 [3].

Goeppertia Nees encompasses an estimated 260 species, the great majority of which were transferred from Calathea G.Mey. following the demonstration by Borchsenius, Suárez and Prince in 2012 that Calathea as previously circumscribed was polyphyletic [2]. Goeppertia angustifolia is a wild species, not a cultivar; the questions of authorship and nomenclature that apply to it are therefore those of botanical nomenclature rather than horticultural origination. The registry records the species as being in cultivation (in_cultivation: true), though no authoritative cultivation account specific to this species has been identified in sources retrieved.

The accepted name Goeppertia angustifolia (Körn.) Borchs. & S.Suárez rests on a basionym established by the German botanist Friedrich August Wilhelm Körnicke. Körnicke described the plant as Calathea angustifolia Körn. in his Monographiae Marantearum prodromus, published in the Bulletin de la Société Impériale des Naturalistes de Moscou (volume 35, pages 1–147) in 1862 [2]. That same 1862 publication introduced Calathea chlorosticta Körn., a name treated as a further synonym of Goeppertia angustifolia under current taxonomy, as recorded in the GBIF Backbone Taxonomy [3].

The combination transferring Calathea angustifolia Körn. to Goeppertia was published by Finn Borchsenius, Luz Stella Suárez and Linda Prince in their 2012 study Molecular Phylogeny and Redefined Generic Limits of Calathea (Marantaceae), in Systematic Botany 37(3): 620–635 [2]. That paper published a total of 246 new combinations, moving species from the polyphyletic Calathea G.Mey. into the resurrected genus Goeppertia Nees [2]. No amendment or correction to the combination Goeppertia angustifolia (Körn.) Borchs. & S.Suárez has been identified in the sources retrieved.

The epithet angustifolia derives from the Latin for narrow-leaved and is a purely descriptive botanical epithet. It does not carry cultivar or trade significance. The following names resolve to this accepted species according to POWO and the GBIF Backbone Taxonomy [1][3]:

• Goeppertia angustifolia (Körn.) Borchs. & S.Suárez, accepted name
• Calathea angustifolia Körn., synonym
• Calathea chlorosticta Körn., synonym

The trade continues to list specimens of this species under the synonym Calathea angustifolia, a usage that does not reflect current taxonomic consensus as established by POWO [1].

A detailed morphological circumscription of Goeppertia angustifolia is not reproduced in the POWO or GBIF Backbone Taxonomy records retrieved for this page [1][3]. The primary diagnostic account resides in Körnicke's 1862 protologue and in the 2012 revision by Borchsenius, Suárez and Prince [2]. Limited authoritative sources available; further research needed.

Plants of the World Online records Colombia among the documented occurrences for this taxon, cited in the synonym record for Calathea angustifolia Körn. [1]. The POWO synonym record also notes Bernal, Gradstein and Celis, Catálogo de plantas y líquenes de Colombia (2015), as one of the sources citing this name, providing further support for the presence of this taxon in Colombia [1]. The POWO genus record for Goeppertia confirms that the genus ranges across Mexico to Tropical America, with Colombia listed among the native territories [1].

The registry fact pack does not carry a populated native_range or habitat field for this species. The full accepted-taxon entry at POWO (POWO ID 9366933) is the primary authoritative statement of native range for the accepted combination. Limited authoritative sources available; further research needed.

No International Cultivar Registration Authority (ICRA) has been appointed for Marantaceae. The International Society for Horticultural Science maintains the list of appointed ICRAs by family; Marantaceae does not appear on that list [4]. The genus record for Goeppertia in this registry carries a null icra_authority field, consistent with that status [3]. Because no ICRA has been appointed for this family, there is no designated body to receive, examine, or publish new cultivar registrations for Goeppertia under the International Code of Nomenclature for Cultivated Plants (ICNCP).

Goeppertia angustifolia itself is a wild species with no documented cultivar epithets in the registry. The ICNCP requires a cultivar epithet to be enclosed in single quotation marks and prohibits its italicisation; those conventions are relevant to cultivar names attributed to this species, of which none are currently recorded. The absence of an ICRA for Marantaceae is a documented fact about the family, not a gap specific to this species.

The registry records Goeppertia angustifolia as being in cultivation. The name Calathea angustifolia Körn. was recorded in Govaerts (1999), World Checklist of Seed Plants, prior to the 2012 transfer, as documented in the POWO synonym record [1]. Plants of the World Online confirms the synonym relationship and the accepted name, providing the authoritative reference point for any horticultural use of either name [1].

The name-persistence pattern under which horticultural trade continues to use Calathea angustifolia rather than the accepted Goeppertia angustifolia is consistent with the broader pattern documented at the genus level by Borchsenius, Suárez and Prince (2012), who noted that the large number of transferred species had a significant horticultural following under the name Calathea [2]. Additional combinations in Goeppertia published after 2012 in journals including Phytotaxa reflect the ongoing nomenclatural work arising from that revision [5]. No authoritative cultivation account specific to Goeppertia angustifolia has been identified; further research needed.
