Goeppertia insignis

Goeppertia insignis (W.Bull ex W.E.Marshall) J.M.A.Braga, L.J.T.Cardoso & R.Couto is an accepted species of Marantaceae placed in the genus Goeppertia Nees, which Plants of the World Online (POWO), maintained by the Royal Botanic Gardens, Kew, recognises as encompassing approximately 260 accepted species [1]. The species is a perennial herb consistent with the broader habit documented for the genus across its neotropical range [1]. Its native distribution is recorded by POWO as Brazil (Rio de Janeiro), in the wet tropical biome [1].

The plant has been in horticultural circulation since at least the early twentieth century. The basionym Maranta insignis W.Bull ex W.E.Marshall appeared in print in 1902, and a subsequent Ward observation in The Gardener's Chronicle volume 39 (1906) documented the species in horticultural observation [2]. For several decades after 1955 the species was known in the trade primarily as Calathea lancifolia Boom, the name under which it continues to circulate in horticulture according to the registry nomenclatural record [1]. A nomenclatural revision published in Phytotaxa in 2017 established the currently accepted name and resolved the competing synonymy [2].

The GBIF Backbone Taxonomy records the species under the stable key 11035519, consistent with the POWO treatment [4].

The accepted name is Goeppertia insignis (W.Bull ex W.E.Marshall) J.M.A.Braga, L.J.T.Cardoso & R.Couto. The combination was published by Braga, Silva, Cardoso, Joffily and Couto in Phytotaxa 312(1): 143–146, dated 4 July 2017 [2]. The authority string in the accepted name abbreviates to J.M.A.Braga, L.J.T.Cardoso & R.Couto following the conventions of the International Plant Names Index (IPNI) and POWO [1][3]. The full authorship of the 2017 paper is Braga, J.M.A., Silva, F.A., Cardoso, L.J.T., Joffily, A. and Couto, R.S., all affiliated with Brazilian institutions; the abbreviated form reflects IPNI standard practice and is confirmed by the primary record [2].

The basionym is Maranta insignis W.Bull ex W.E.Marshall, first described in The Gardener's Chronicle, series 3, volume 32, page 63, in 1902 [3]. The IPNI record for the basionym confirms that the epithet author is given as W.Bull ex W.E.Marshall, indicating that the name was attributed to William Bull but validly published by W.E. Marshall [3]. The IPNI identifier for the accepted combination is urn:lsid:ipni.org:names:77174285-1 [1].

POWO records four synonyms for this species. First, Maranta insignis W.Bull ex W.E.Marshall (1902) is the basionym as noted above. Second, Calathea insignis (W.Bull ex W.E.Marshall) W.Bull, published in The Gardener's Chronicle, series 3, volume 44, page 63, in 1908, is treated by POWO as a later illegitimate homonym: the epithet insignis had already been applied to a different species within Calathea, rendering the 1908 combination illegitimate [1]. Third, Calathea lancifolia Boom, published in Acta Botanica Neerlandica 4: 169 in 1955, was the name coined by H.J. Boom to circumvent the illegitimate homonym and became the prevailing horticultural designation for several decades [1]. Fourth, Goeppertia lancifolia (Boom) Borchs. & S.Suárez, the combination published by Borchsenius, Suárez and Prince in Systematic Botany 37(3): 631 in 2012 as part of a large-scale phylogenetic revision of the genus, is now likewise treated as a synonym [5].

The 2017 Braga et al. paper explained that the correct name under Goeppertia for this taxon is derived from the older epithet insignis rather than from lancifolia, because the 1902 basionym takes priority under the International Code of Nomenclature for algae, fungi, and plants [2]. The paper also designated types and corrected authorship of basionyms across several Goeppertia species [2].

A registry conflict is noted for the synonym row for Calathea lancifolia: the registry cites Borchsenius, Suárez and Prince (2012) as its source, but POWO and IPNI confirm that the ultimate synonymisation of Calathea lancifolia under Goeppertia insignis was effected by the 2017 Braga et al. paper [1][2]. The 2012 paper established Goeppertia lancifolia (Boom) Borchs. & S.Suárez as a name within Goeppertia; that combination is itself now a synonym of G. insignis [5]. A human reviewer should assess whether the registry source attribution for the Calathea lancifolia synonym row requires correction.

Goeppertia insignis is a perennial herb, consistent with the broader habit documented for the genus Goeppertia across its neotropical range as recorded by POWO [1]. The 2017 Phytotaxa paper by Braga et al. provides nomenclatural corrections and type designations for this species within a treatment covering several Goeppertia entities, and diagnostic morphological characters are addressed within that primary publication [2].

Limited authoritative sources available; further research needed for a full morphological description of this species beyond the nomenclatural treatment.

Plants of the World Online records the native range of Goeppertia insignis as Brazil, specifically the Rio de Janeiro state, classified within the Brazil Southeast region under the POWO distribution system [1]. The species is assigned to the wet tropical biome [1]. No additional range data, altitudinal limits, or detailed habitat qualifications beyond these are recorded in the authoritative sources consulted for this page.

Limited authoritative sources document the precise ecological parameters of this species in its native Rio de Janeiro habitat; further research needed for a full ecological characterisation.

POWO confirms that Goeppertia insignis is in cultivation [1]. Evidence for the species in horticultural circulation extends to at least the early twentieth century: the basionym Maranta insignis W.Bull ex W.E.Marshall was published in 1902 in The Gardener's Chronicle, a periodical that documented plants in cultivation in Britain during that period [3]. A Ward observation in The Gardener's Chronicle volume 39 (1906) provided an early record of the plant in horticultural observation [2].

The synonym Calathea lancifolia Boom (1955) is recorded in the registry as a name in continued horticultural use, indicating that the trade has circulated this species under the lancifolia epithet for several decades [1]. The 2017 nomenclatural revision by Braga et al. established the correct name as Goeppertia insignis, but the horticultural synonym predates that correction by more than sixty years [2]. The genus Goeppertia as a whole continues to be referred to in the trade as calatheas, reflecting the historical prevalence of the genus name Calathea G.Mey. prior to the 2012 phylogenetic revision by Borchsenius, Suárez and Prince [5].

Beyond these nomenclatural and historical records, limited authoritative sources document the specific cultivation conditions or horticultural performance of this species as assessed by botanic gardens or university extension services; further research needed.

The single cultivar recorded in this registry under Goeppertia insignis is 'Rattlesnake'. The International Code of Nomenclature for Cultivated Plants (ICNCP) requires a cultivar epithet to be enclosed in single quotation marks; the epithet 'Rattlesnake' is recorded in this registry in conformance with that convention [6].

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

No International Cultivar Registration Authority has been appointed for Marantaceae [6]. The International Society for Horticultural Science appoints ICRAs through its Commission for Cultivar Registration, and each authority operates within the provisions of the ICNCP [6]. Marantaceae does not appear among the families for which an ICRA has been appointed. By contrast, the adjacent order Araceae is served by the International Aroid Society, which holds the ICRA appointment for that family [7]. No equivalent body exists for Marantaceae or for its constituent genera including Goeppertia, and no authority currently maintains a complete, adjudicated register of Goeppertia cultivar epithets.

No patent number is recorded in the registry for the cultivar 'Rattlesnake', and no plant patent document for this cultivar has been located in the authoritative sources consulted for this page.
