Flora of Ceará, Brazil: Talinaceae

Abstract

The aim of this study was to conduct a floristic inventory and update the geographical distribution of Talinaceae species in Ceará state, in the Northeast Region of Brazil. The study was based on a comparative analysis of morphological characters of specimens deposited in the EAC, ESA, HCDAL, HUEFS, HUVA, HVASF, MOSS and RB herbaria, specialized literature, photos of type collections, and field expeditions conducted between March 2015 and April 2022. For the state, Talinum fruticosum and T. paniculatum have been recorded, which prefer drier vegetations, such as Stepic Savanna (Caatinga and Carrasco) and Semideciduous Seasonal Forest (Mata Seca), but also grow in areas that are more humid. The species occur in eight conservation units in Ceará: Dunas da Lagoinha and Serra de Meruoca Environmental Protection Areas, Aiuaba Ecological Station, Sobral National Forest, Ubajara National Park, Pedra da Andorinha Wildlife Refuge, Serra das Almas and Fazenda Trussú Private Natural Heritage Reserves. An identification key, descriptions, photographs, and comments about the geographical distribution, taxonomic relationships, and phenology are provided for the species.

Introduction

The family Talinaceae (Caryophyllales) comprises 28 species that belong to three genera: Amphipetalum Bacigalupo, with one species recorded for Paraguay and Bolivia; Talinum Adans, with 15 species distributed in Africa and the Americas; and Talinella Adans., with 12 species endemic to Madagascar (Nyffeler & Eggli 2010Nyffeler R & Eggli U (2010) Disintegrating Portulacaceae: a new familial classification of the suborder Portulacineae (Caryophyllales) based on molecular and morphological data. Taxon 59: 227-240.). In Brazil, the family is represented only by Talinum fruticosum (L.) Juss. and T. paniculatum (Jacq.) Gaertn., which both occur in the state of Ceará (Hassemer 2022Hassemer G (2022) Talinaceae. In: Flora e Funga do Brasil. Jardim Botânico do Rio de Janeiro.

).

Its species were traditionally treated in Portulacaceae s.l. However, based on molecular studies, the group was split into four families: Anacampserotaceae, Montiaceae, Portulacaceae s.s., and Talinaceae (Carolin 1993Carolin RC (1993) Portulacaceae.

Botanical Journal of the Linnean Society 181: 1-20.). Talinaceae consist of succulent herbs or subshrubs with the following: generally tuberous roots; alternate, entire, glabrous to tomentose leaves; terminal, paniculate inflorescences or inflorescences reduced to one flower per leaf axil; showy, bisexual, actinomorphic flowers with numerous stamens and a superior, unilocular, 3(–5)-carpellate, pluriovulate ovary; and fruit that is a loculicidal capsule (Souza & Lorenzi 2019Souza VC & Lorenzi H (2019) Botânica Sistemática.

).

The Talinaceae species in Brazil are commonly reported as crop invasives (Mendoza & Wood 2013; Souza & Lorenzi 2019Souza VC & Lorenzi H (2019) Botânica Sistemática. Guia ilustrado para identificação das famílias de fanerógamas nativas e exóticas no Brasil, baseado em APG IV Instituto Plantarum, Nova Odessa. 768p.) and unconventional food and medicinal plants (Madeira & Botrel 2018Madeira NR & Botrel N (2018) Talinum paniculatum e T. triangulare: major gomes e cariru. In: Coradin L, Camillo J, Pareyn F & Germain C (eds.) Espécies nativas da fora brasileira de valor econômico atual ou potencial: plantas para o futuro: Região Nordeste.

Dissertação de Mestrado. Universidade Federal de Goiás, Goiânia. 108p.). The leaves are rich in protein, calcium, iron, zinc and molybdenum (Manhães et al. 2008Manhães LRT, Marques MM & Sabaa-Srur AUO (2008) Composição química e do conteúdo de energia do cariru (Talinum esculentum Jacq.). ActaAmazônica 38: 307-310.), and are a source of food that can be consumed raw in salads (Kinupp 2007Kinupp V (2007) Plantas alimentícias não-convencionais da região metropolitana de Porto Alegre - RS. Tese de Doutorado. Universidade Federal do Rio Grande do Sul, Porto Alegre. 562p.) or in stews, soups, and omelets (Madeira & Botrel 2018Madeira NR & Botrel N (2018) Talinum paniculatum e T. triangulare: major gomes e cariru. In: Coradin L, Camillo J, Pareyn F & Germain C (eds.) Espécies nativas da fora brasileira de valor econômico atual ou potencial: plantas para o futuro: Região Nordeste. Ministério do Meio Ambiente, Brasília. Pp. 326-334.). Talinum fruticosum has a laxative property (Agra et al. 2008Agra MF, Silva KN, Basílio IJLD, Freitas PG & Barbosa Filho JM (2008) Survey of medicinal plants used in the region Northeast of Brazil. Revista Brasileira de Farmacognosia 18: 427-508.), while T. paniculatum is used in home medicine to treat wounds, inflammation, and skin conditions (Tolouei et al. 2019Tolouei SEL, Palozi RAC, Tirloni AS, Marques AAM, Schaedler MI, Guarnier LP, Silva AO, Almeida VP, Budel JM, Souza RIC, Santos AC, Silva DB, Lourenço ELB, Dalsenter PR & Gasparotto Júnior AG (2019) Ethnopharmacological approaches to Talinum paniculatum (Jacq.) Gaertn. - Exploring cardiorenal effects from the Brazilian Cerrado. Journal of Ethnopharmacology 238: 111873.).

In Brazil, studies about Talinaceae are still incipient. The first reference is a treatment by Rohrbach (1872)Rohrbach P (1872) Portulacaceae. In: Martius CFP & Urban I (eds.) Flora brasiliensis. Fleicher, Leipzig. Vol. 14, pars 2, pp. 293-306, t. 62-69., in Flora brasiliensis, where the author reported two species: Talinum patens (Jacq.) Willd. (currently a synonym of T. paniculatum) and T. racemosum (L.) Rohrb. Subsequently, representatives of the family were cited in some state and local floras, such as Rio de Janeiro (Teixeira 1959Teixeira L (1959) Portulacaceae da cidade do Rio de Janeiro. Rodriguésia 21: 299-316.), Rio Grande do Sul (Mattos 1984Mattos JR (1984) Portulacáceas. In: Reitz R (ed.). Flora Ilustrada Catarinense, Vol. PORT.

For the state of Ceará, no taxonomic treatment specifically for the family had been published. The species of Talinaceae have only been mentioned in general floristic studies conducted in the municipality of Crateús (Araújo et al. 2011Araújo FS, Costa RC, Lima JR, Vasconcelos SF, Girão LC, Sobrinho MS, Bruno MMA, Souza SSG, Nunes EP, Figueiredo MA, Lima-Verde LW & Loiola MIB (2011) Floristics and life-forms along a topographic gradiente, central-western Ceará, Brazil.

), which purposes to provide data to broaden the knowledge about the flora of Ceará, the aim of this study was to conduct a floristic-taxonomic survey and update the geographical distribution of the species of Talinaceae in the state of Ceará. Here, an identification key, descriptions, photographs, and comments on the geographical distribution, taxonomic relationships, and phenology are provided for the species.

Material and Methods

The floristic-taxonomic survey was based on material from field expeditions carried out from March 2015 to April 2022 and an analysis of collections in the EAC, ESA, HCDAL, HUEFS, HUVA, HVASF, MOSS, and RB (acronyms according to Thiers, continuously updated) herbaria. We photographed, collected, and processed the botanical material following the methods proposed by Mori et al. (1989)Mori AS, Silva LAM, Lisboa G & Coradin L (1989) Manual de manejo do herbário fanerogâmico. 2a ed. Centro de Pesquisa do Cacau, Ilhéus. 103p..

Taxonomic identifications were made by consulting specialized literature (Coelho 2009Coelho AAOP (2009) Portulacaceae. In: Alves M, Araújo MF, Maciel JR & Martins S (eds.) Flora de Mirandiba.

). For the morphological descriptions, we adopted the terminology proposed by Radford (1974)Radford AE (1974) Fundamentals of plant systematics. Harper & Row, Nova York. 498p. and Gonçalves & Lorenzi (2011)Gonçalves EG & Lorenzi H (2011) Morfologia vegetal: organografia e dicionário ilustrado de morfologia das plantas vasculares. 2a ed.

. The identification key and the descriptions of the genus and species are based on samples collected in Ceará. The photographic plate was made using GIMP 2.10.22 (GIMP 2022GIMP (2022) GIMP 2.10.22 Released. Available at <https://www.gimp.org/news/2020/10/07/gimp-2-10-22-released/>. Access on 12 March 2022.

).

We obtained data about the geographical distribution, vegetation types, popular names, and phenology from labels of the specimens analyzed. The distribution map of the species, which indicates the type of vegetation where they occur, was drawn by delimiting 0.5° longitude × 0.5° latitude grid cells. For specimens with no coordinates, we used the coordinates of the city where they were collected, which were obtained using the “geoLoc” tool (CRIA 2022CRIA - Centro de Referência em Informação Ambiental (2022) speciesLink. Available at <https://specieslink.net/>. Access on 2 April 2022.
https://specieslink.net/...
).

For the vegetation types, we adopted the classification proposed by Figueiredo (1997)Figueiredo MA (1997) A cobertura vegetacional do Ceará: unidades fitoecológicas. In: Ceará. Atlas do Ceará. Vol. 1. Edições IPLANCE, Fortaleza. Pp. 28-29. and the Brazilian Vegetation Technical Manual (IBGE 2012IBGE - Instituto Brasileiro de Geografia e Estatística (2012) Manual técnico da vegetação brasileira. 2a ed.

), where we identified the following: Semideciduous Seasonal Forest (Dry Forest), Dense Ombrophilous Forest (Humid Forest), Stepic Savanna (Caatinga and Carrasco), Mixed Dicotylus-Palmaceous Forest (Carnaubal), and Vegetation under Fluvial and/or Lacustrine Influence (Ciliary Forest).

Results and Discussion

For the state of Ceará, two species have been recorded, Talinum fruticosum (L.) Juss. and T. paniculatum (Jacq.) Gaertn, which are found mainly in the drier areas of Steppic Savannah (Caatinga and Carrasco) and Seasonal Semideciduous Forest (Dry Forest). However, they also occur in humid areas of Dense Ombrophilous Forest and Vegetation under Fluvial and/or Lacustrine Influence (Ciliar Forest). The species occur at elevations up to 470 m (T. fruticosum) and 684 m (T. paniculatum) and are generally associated with shady locations and fertile soils.

The occurrence of the species was confirmed for eight conservation units (CU): Dunas da Lagoinha Environmental Protection Area (Talinum fruticosum), Serra da Meruoca Environmental Protection Area (Talinum paniculatum), Aiuaba Ecological Station (Talinum fruticosum and T. paniculatum); Sobral National Forest, Ubajara National Park and Pedra da Andorinha Wildlife Refuge (Talinum fruticosum); Serra das Almas Private Natural Heritage Reserve (Talinum fruticosum and T. paniculatum); and Fazenda Trussú Private Natural Heritage Reserve (Talinum fruticosum).

Talinum fruticosum has a cymose, terminal inflorescence, with a truncated peduncle, pink-petaled flowers, and tuberculate seeds. These characteristics distinguish it from T. paniculatum, which has a terminal, panicle inflorescence, cylindrical peduncle, yellow- or pink-petaled flowers, and verrucous seeds.

This species is widespread, with an area of occurrence ranging from the United States, through Mexico, Nicaragua and South America, to northern Argentina (Mendoza & Wood 2013Mendoza JM & Wood JRI (2013) Taxonomic revision of Talinum (Talinaceae) in Bolivia with a note on the occurrence of Phemeranthus (Montiaceae). Kew Bulletin 68: 233-247.). Since it has a wide range, it was categorized by the IUCN (2001)IUCN (2001) IUCN Red List Categories and Criteria: Version 3.1. IUCN, Gland and Cambridge. 30p. as Least Concern (LC) (Mendoza & Wood 2013Mendoza JM & Wood JRI (2013) Taxonomic revision of Talinum (Talinaceae) in Bolivia with a note on the occurrence of Phemeranthus (Montiaceae). Kew Bulletin 68: 233-247.). Its occurrence is confirmed for all regions of Brazil, where it inhabits the Amazon, Caatinga, Cerrado, Atlantic Forest, and Pantanal domains (Hassemer 2022Hassemer G (2022) Talinaceae. In: Flora e Funga do Brasil. Jardim Botânico do Rio de Janeiro. Available at <https://floradobrasil.jbrj.gov.br/FB604439>. Access on 5 March 2022.
https://floradobrasil.jbrj.gov.br/FB6044...
). In Ceará, it has been recorded in Stepic Savanna vegetation (Caatinga and Carrasco), Semideciduous Seasonal Forest (Dry Forest) and Vegetation under Fluvial and/or Lacustrine Influence (Ciliar Forest), at elevations up to 470 m. It has been recorded in Dunas da Lagoinha Environmental Protection Area, Aiuaba Ecological Station, Sobral National Forest, Ubajara National Park, Pedra da Andorinha Wildlife Refuge and Serra das Almas and Fazenda Trussú Private Natural Heritage Reserves.

It has been collected with flowers from January to May and in October and with fruits in January, March, and April.

Its leaves are used as human food, in salads, and the species has ornamental potential (Kissmann & Groth 1995Kissmann KG & Groth D (1995) Plantas infestantes e Nocivas. Vol. III. Basf, São Bernardo do Campo. Pp. 348-354.).

The popular names are beldroega-graúda, cariru, feijão das dunas, manjongome, manjoãogomes.

Talinum paniculatum is easily recognized by its paniculiform inflorescences with a cylindrical peduncle, flowers with yellow to pink petals, and warty seeds.

This species is widely distributed in tropical America, with an area of occurrence that ranges from the United States, through Mexico, the Caribbean region and South America, to northern Argentina (Mendoza & Wood 2013Mendoza JM & Wood JRI (2013) Taxonomic revision of Talinum (Talinaceae) in Bolivia with a note on the occurrence of Phemeranthus (Montiaceae). Kew Bulletin 68: 233-247.). Since it occurs throughout the Neotropical region, the IUCN (2001)IUCN (2001) IUCN Red List Categories and Criteria: Version 3.1. IUCN, Gland and Cambridge. 30p. categorized it as Least Concern (LC) (Mendoza & Wood 2013Mendoza JM & Wood JRI (2013) Taxonomic revision of Talinum (Talinaceae) in Bolivia with a note on the occurrence of Phemeranthus (Montiaceae). Kew Bulletin 68: 233-247.). Its occurrence is confirmed for all of Brazil, and it is present in the Amazon, Caatinga, Cerrado, Atlantic Forest, Pantanal, and Pampa domains (Hassemer 2022Hassemer G (2022) Talinaceae. In: Flora e Funga do Brasil. Jardim Botânico do Rio de Janeiro. Available at <https://floradobrasil.jbrj.gov.br/FB604439>. Access on 5 March 2022.

). In the state of Ceará, it has been recorded in Stepic Savanna (Caatinga and Carrasco), Semideciduous Seasonal Forest, Dense Ombrophilous Forest (Humid Forest), and Vegetation under Fluvial and/or Lacustrine Influence (Ciliar Forest), at elevations up to 684 m. This species occurs in Serra da Meruoca Environmental Protection Area, Aiuaba Ecological Station, and Serra das Almas Private Natural Heritage Reserve.

It has been collected with flowers from February to May and with fruits in February, April, May, and June.

The leaves can be eaten raw or cooked and the entire aerial part of the plant can be used for animal feed (Kissmann & Groth 1995Kissmann KG & Groth D (1995) Plantas infestantes e Nocivas. Vol. III. Basf, São Bernardo do Campo. Pp. 348-354.).

The popular names are beodroega, beldroega, botãozinho-rosa.
