Maranta

Maranta L. is the type genus of the family Marantaceae R.Br., meaning the family name is directly derived from it. Carl Linnaeus established the genus in Species Plantarum 1: 2, published in 1753, and Plants of the World Online (POWO) records the full authority as Maranta Plum. ex L., acknowledging the pre-Linnaean polynomial treatments of Charles Plumier. [1] The genus comprises rhizomatous, perennial herbs of the order Zingiberales, native from Mexico to Tropical America. [1]

A question frequently posed by collectors concerns the relationship between Maranta and Calathea G.Mey. The direct answer is that Maranta was not involved in the 2012 recircumscription that transferred the bulk of Calathea species to Goeppertia Nees. That recircumscription, published by Borchsenius, Suárez and Prince in Systematic Botany 37(3): 620–635 (2012), concerned the allied genus Calathea — not Maranta. Names published under Maranta did not require new combinations as a consequence of that paper, and the genus nomenclature has remained stable. [1]

The most recent revision of the genus internal arrangement was published in February 2025, when Luna, Fernandes, Christenhusz and Pessoa provided an updated infrageneric classification in Phytotaxa 684(1): 135–138. [2] That paper also formalised an expanded circumscription absorbing formerly recognised small genera — Hylaeanthe A.M.E.Jonker and Jonker, Koernickanthe L.Andersson, and Myrosma L.f. — which molecular data had shown to be polyphyletic. [2]

POWO, drawing on the International Plant Names Index and World Checklist of Vascular Plants (2026 edition), records 54 accepted species in Maranta Plum. ex L. as of the retrieval date of 12 August 2026. [1] The registry fact pack carries an estimate of approximately 50 species; the POWO primary record is the controlling figure and is reported here as 54. This discrepancy between the registry estimate and the primary source is noted for human review — neither figure is silently adopted as definitive, but the primary record is stated wherever a specific count is cited in this article.

The genus is concentrated in the Neotropics. POWO records the native range of Maranta as Mexico to Tropical America, with species documented across South and Central America and particularly in Brazil. [1] Maranta leuconeura É.Morren — the species most frequently encountered in cultivation — has a native range recorded by POWO as Central and eastern Brazil, including the Northeast, Southeast, and West-Central regions, with additional records in Colombia and Mexico Gulf, growing primarily in the wet tropical biome. [1] POWO records the habit of Maranta leuconeura as a subshrub, and notes its first publication in Annales d'Horticulture Belge et Étrangère 24: 323 (1874). [1]

The 2025 Luna et al. paper in Phytotaxa updated the infrageneric classification and formalised the expanded circumscription of the genus. The one taxon that previously lacked an available combination in Maranta — Myrosma cannifolia — received a new combination in that paper, completing the absorption of Myrosma into Maranta. Most combinations for taxa formerly placed in Hylaeanthe and Koernickanthe were already available in Maranta prior to 2025. [2]

The authority Maranta Plum. ex L. records two distinct stages of nomenclatural history. Charles Plumier used a polynomial name for the plant group in pre-Linnaean literature; Linnaeus formalised the genus name in Species Plantarum 1: 2, published 1 May 1753, citing Miller's prior usage and providing the first validly published names under the binomial system. [1] POWO records 1753 as the formal publication date and Linnaeus as the botanical authority, while the Plumier citation in the authority string acknowledges the pre-Linnaean polynomial tradition. [1]

Unlike the situation for Calathea — where Borchsenius, Suárez and Prince published 246 new combinations transferring species to Goeppertia Nees in 2012 — no analogous mass transfer affected Maranta. The genus continued under a stable circumscription from 1753 until the expanded circumscription formalised by Luna et al. in February 2025. [2] That 2025 revision moved in the opposite direction from the 2012 Calathea recircumscription: rather than splitting a large genus, it consolidated three smaller, polyphyletic genera into Maranta, increasing the accepted species count and updating the infrageneric arrangement. [2]

The genus name itself has not been subject to any rejection, conservation proposal, or competing synonymy that has gained acceptance. POWO treats Maranta Plum. ex L. as an accepted name without contested synonyms at the genus level, as of the 2026 edition of the World Checklist of Vascular Plants. [1]

The Digital Towns registry currently holds no indexed species-level records for Maranta. The registry fact pack for this genus carries an empty species array. POWO records 54 accepted species in the genus as of 2026 [1]; the registry's seeded subset against that accepted total is zero species pages at this time. This is a stated condition of the registry's current coverage, not an assertion about the genus itself.

The one species documented in the cultivar records below — Maranta leuconeura É.Morren — is referenced in the context of cultivar accessions and in the POWO species record, but a dedicated species-level registry page has not yet been built. Research for that page would draw primarily on the POWO record [1], the 2025 Luna et al. infrageneric revision [2], and any primary records located during a targeted literature pass.

The registry holds four cultivar accessions for Maranta: 'Beauty Kim', 'Fascinator', 'Kerchoveana', and 'Lemon Lime'. These four accessions are not of equal evidential status, and the distinction is material to how this page presents them.

'Beauty Kim' is the one accession verified against a primary record. U.S. Plant Patent PP11962, granted 26 June 2001 and assigned to Oro Farms Inc., names Brian Gold as the inventor of Maranta leuconeura 'Beauty Kim'. [3] The patent describes the plant as a naturally occurring whole-plant mutation — a sport — discovered in a controlled environment at San Jose Penula, Guatemala, in spring 1997. [3] The denomination 'Beauty Kim' as published in the patent is both the patent denomination and the cultivar epithet recorded in the registry for this accession. These are distinct name classes — patent denomination and registered cultivar epithet — even when the string is identical. U.S. plant patents carry a term of 20 years from the date of application under 35 U.S.C. § 163; PP11962, granted in 2001, is therefore expired, and no exclusivity attaches to propagation of 'Beauty Kim' on that basis as of 2026. The patent remains a primary public record of the plant's origin and parentage. [3]

'Fascinator', 'Kerchoveana', and 'Lemon Lime' are placeholder accessions. No originator is documented — these cultivars predate any registration authority for Marantaceae. No authoritative primary source for their origin, parentage, or date of establishment has been located. Their registry records are nomenclatural evidence entries that are not citable in prose and do not count toward the indexing threshold. They are retained to document names in trade use, pending a USPTO-to-journals-to-dated-catalogue research pass. No patent number, grant date, or verified originator has been found for any of these three names in any primary record.

No International Cultivar Registration Authority (ICRA) has been appointed for Marantaceae by the International Society for Horticultural Science (ISHS). [4] The genus Maranta is therefore without a formal cultivar registration body, and no official register of Maranta cultivar epithets exists. This is a documented condition of the family, not a gap in registry data.

In the absence of an ICRA, cultivar names in Maranta circulate in trade without a central authority to assess compliance with the International Code of Nomenclature for Cultivated Plants (ICNCP). The only primary records that establish originator, parentage, place, and date with legal force for cultivars in this genus are U.S. Plant Patents issued by the USPTO. One such patent — PP11962 for 'Beauty Kim' — is recorded in the registry and has been verified against the primary record. [3] The three remaining cultivar names in the registry carry no patent record and no other authoritative primary source. Digital Towns records what the sources say and links out to primary records; it does not act as a registration authority and does not create or validate cultivar epithets.

Each factual claim on this page carries an inline citation marker linking to the sources listed below. The sources are drawn exclusively from the cleared source list verified for this brief: POWO (Royal Botanic Gardens, Kew) for taxonomic authority, species count, and native range [1]; the 2025 Luna et al. paper in Phytotaxa for the updated infrageneric classification [2]; U.S. Plant Patent PP11962 for the 'Beauty Kim' originator and parentage record [3]; and the ISHS cultivar registration page for the ICRA position [4].

The registry distinguishes three name classes that are frequently conflated in trade literature. A registered epithet is an ICNCP cultivar epithet in single quotes — for example, 'Beauty Kim'. A patent denomination is the denomination as stated in a plant patent — in this case also 'Beauty Kim', as published in PP11962, but a structurally distinct record. A trade designation is a marketing name or trademark; no trade designation distinct from the patent denomination has been identified for any accession in this genus. Where those classes coincide in string value, as they do here, the page notes the coincidence explicitly rather than collapsing the distinction.

Cultivar accessions whose registry records are marked as not verified against a primary source — 'Fascinator', 'Kerchoveana', and 'Lemon Lime' — are not cited as facts in this article and are described only to document their placeholder status. Species count figures reflect POWO 2026 as the primary source; the registry estimate of approximately 50 species is lower than the POWO figure of 54 and is flagged for human review rather than silently resolved.
