Goeppertia propinqua

Goeppertia propinqua (Poepp. & Endl.) Borchs. & S.Suárez is an accepted species in the family Marantaceae, order Zingiberales. Plants of the World Online (POWO), maintained by the Royal Botanic Gardens, Kew, carries this name as accepted under POWO identifier 7864201 and records the species as a perennial growing primarily in the wet tropical biome [1]. The GBIF Backbone Taxonomy independently records the same accepted name under GBIF key 7864201 [2].

The species is one of approximately 260 accepted species in Goeppertia Nees, the largest genus in Marantaceae [3]. That genus was substantially reconstituted when Borchsenius, Suárez and Prince published 246 new combinations in 2012, following a molecular phylogenetic analysis demonstrating that Calathea G.Mey. as previously circumscribed was polyphyletic [3]. Goeppertia propinqua was among the names established by that revision. The registry records this species as in cultivation, though no authoritative source describing its specific cultivation characteristics has been located for this article.

The accepted name Goeppertia propinqua (Poepp. & Endl.) Borchs. & S.Suárez carries an authority string that records two distinct nomenclatural events. The parenthetical authors, Eduard Friedrich Poeppig and Stephan Friedrich Ladislaus Endlicher, are credited with the original description of the taxon in the nineteenth century, based on collected South American material. Their names form the basionym authority. A subsequent transfer by J.G. Körner placed the plant under Calathea G.Mey. as Calathea propinqua (Poepp. & Endl.) Körn., the name under which the species was treated in the literature for an extended period [3].

The most recent combination, into Goeppertia Nees, was published by Borchsenius, Suárez and Prince on 1 September 2012 in Systematic Botany 37(3): 620–635 [3]. That paper established the current accepted name and rendered Calathea propinqua (Poepp. & Endl.) Körn. a heterotypic synonym. The registry also records Calathea trifasciata as a synonym resolved by the same 2012 revision [3]. The precise relationship of Calathea trifasciata to the Poeppig and Endlicher basionym requires confirmation against the primary protologue, which has not been located in sources available for this article.

The protologue of the basionym, as published in the original Poeppig and Endlicher South American botanical survey, has not been retrieved in full text for this article; the precise volume and page citation for the original combination have not been verified against a primary copy. The date and publication locus of the Körner transfer have likewise not been verified. Limited authoritative sources available; further research needed on the protologue provenance and the date and locus of the Körner transfer.

The GBIF Backbone Taxonomy records the accepted name independently of POWO, corroborating the nomenclatural conclusion of the 2012 revision [2]. The trade continues to list material of this species under Calathea propinqua, reflecting the incomplete uptake of the reclassification in horticultural commerce.

Plants of the World Online records Goeppertia propinqua as a perennial and places the species in the wet tropical biome [1]. A precise morphological circumscription distinguishing Goeppertia propinqua from its congeners has not been located in sources available for this article and citable under editorial policy. The original diagnostic description as published in the Poeppig and Endlicher protologue, and any subsequent morphological treatment by Körner at the time of the transfer to Calathea, have not been verified against primary copies.

Limited authoritative sources available; further research needed on the morphological circumscription of this species relative to other accepted species in Goeppertia.

Plants of the World Online records Goeppertia propinqua as growing primarily in the wet tropical biome [1]. The registry fields for native range and habitat are both null, indicating that a full range statement had not been verified against the primary POWO record (identifier 7864201) at the time the registry was seeded. A registry conflict exists between the null native-range value in the registry and the partial range documentable from authoritative sources; a human reviewer is required to resolve this by accessing the POWO species page and populating the registry fields accordingly [1].

The GBIF Backbone Taxonomy records the name under key 7864201 and associates the species with the South American floristic region, consistent with the Poeppig and Endlicher authorship and the broader distribution of Goeppertia in the Neotropics [2]. The full native range, including specific countries and departments, requires verification against the POWO distribution record and the primary floristic literature for the relevant countries.

Limited authoritative sources available for the full native range; further research needed.

The registry records Goeppertia propinqua as in cultivation. Plants of the World Online records the species as a perennial in the wet tropical biome [1], consistent with the growth habit of other members of Goeppertia that have entered cultivation as ornamental foliage plants. No authoritative botanical garden publication, university extension document, or primary literature source describing the cultivation of this species specifically has been located in the sources available for this article.

No cultivars of Goeppertia propinqua are recorded in the Digital Towns registry. No plant patents naming this species as a parent or subject have been located. No International Cultivar Registration Authority has been appointed for Marantaceae; the International Society for Horticultural Science list of appointed authorities does not include Marantaceae [4]. In the absence of an appointed authority, no formal cultivar register exists for Goeppertia, and cultivar epithets applied to plants in this genus carry no standing registration beyond the provisions of the International Code of Nomenclature for Cultivated Plants [3].

Limited authoritative sources available; further research needed on cultivation characteristics, propagation methods, and any institutional holdings of this species in botanical garden collections.

No International Cultivar Registration Authority has been appointed for Marantaceae. The International Society for Horticultural Science publishes the list of appointed registration authorities, and Marantaceae does not appear on that list [4]. The registry fields icra_authority and dt_is_icra are null and false respectively, reflecting this documented absence. The GBIF Backbone Taxonomy record for this species corroborates the accepted name but carries no cultivar registration data [2].

Digital Towns is an applicant and an aggregator. It is not affiliated with, endorsed by, or operating under the International Society for Horticultural Science or any appointed cultivar registration authority. The registry records what authoritative taxonomic sources state and links to those sources; it does not reproduce another register's prose or claim standing it does not hold.
