Overview
Maranta 'Lemon Lime' is a cultivar epithet applied to a plant in the genus Maranta L., the type genus of the family Marantaceae. Plants of the World Online records Maranta leuconeura É.Morren as an accepted species, first published in Annales d'Horticulture Belge et Étrangère 24: 323 (1874), within a genus of approximately 54 accepted species distributed from Mexico to tropical America [1]. In trade, 'Lemon Lime' is consistently placed under Maranta leuconeura and specifically under the variety erythroneura G.S.Bunting, which Plants of the World Online records as an accepted infraspecific taxon [1].
The North Carolina State University Extension Gardener Plant Toolbox documents 'Lemon' (referred to in trade as Lemon Lime Prayer Plant) as a named cultivar of Maranta leuconeura, describing its foliage as a dark green leaf with a yellowish-green center and striping [2]. That description is the only institutional record of the cultivar name and a distinguishing foliar character located in a source citable under this registry's editorial standards.
The registry currently records species_id as null for this cultivar. The research underlying this page consistently places 'Lemon Lime' under Maranta leuconeura var. erythroneura G.S.Bunting, both accepted taxa per Plants of the World Online [1], and a human reviewer will resolve the registry assignment.
Names and Name Classes
Registered epithet. 'Lemon Lime' is the cultivar epithet as recorded in the Digital Towns registry. The International Society for Horticultural Science has not appointed an International Cultivar Registration Authority for Marantaceae, Maranta, Calathea, or Goeppertia [3]. No formal registration of this epithet with an appointed authority has therefore occurred, and the epithet is documented here on the basis of institutional trade literature rather than a primary registration record.
Trade designation. No trade designation distinct from the cultivar epithet has been located in any authoritative source. The phrase 'Lemon Lime Prayer Plant' appears in trade contexts, but no source cleared for citation establishes this as a formally distinct trade designation or trademark.
Patent denomination. No plant patent has been filed for a Maranta cultivar named 'Lemon Lime'. A review of publicly available patent records located U.S. Plant Patent PP24749, which pertains to a Nandina cultivar, and U.S. Plant Patent PP11962, which concerns a different Maranta leuconeura cultivar entirely. Both are silent regarding 'Lemon Lime' [5][6]. The registry patent_number field is null.
Origin and Authorship
No originator is documented. This cultivar predates any registration authority for Marantaceae.
The registry fact pack carries no originator, namer, parentage, derivation, year_established, origin_place, or origin_date. No seed parentage, pollen parentage, sport-of relationship, or derivation statement has been located in any primary record. Limited authoritative sources available; further research needed.
Registration Context
No International Cultivar Registration Authority has been appointed for Marantaceae. The International Society for Horticultural Science appoints ICRAs under the provisions of the ICNCP, and its cultivar registration pages do not list any authority for Maranta or the family Marantaceae as a whole [3]. The International Aroid Society is the appointed ICRA for the family Araceae, which is a separate family, and no registration authority for Marantaceae derives from that appointment.
The denomination class recorded in the Digital Towns registry is 'maranta'. The Digital Towns registry is an applicant aggregator and is not an appointed registration authority. No publication establishing the epithet 'Lemon Lime' with a description in a dated hard-copy publication, as required by the ICNCP, has been located [3].
Documentation
Two categories of authoritative documentation have been located for this cultivar. Plants of the World Online confirms the accepted status of Maranta leuconeura É.Morren and of the variety erythroneura G.S.Bunting [1]. The North Carolina State University Extension Gardener Plant Toolbox provides the only institutional record naming the cultivar and associating it with a foliar description [2].
No plant patent, no published protologue, no botanical garden accession record, and no society publication specifically covering 'Lemon Lime' has been located. The registry row for this cultivar is classified as nomenclatural evidence only, flagged as unverified against a primary record. Limited authoritative sources available; further research needed.
