The Correios launches, this Thursday (22), the special seal of the Mercosur Series: Fauna and Flora – Succulents.The fourteenth philatelic release of 2022 highlights all the relevance and beauty of plants capable of accumulating water in the stem, leaves or even roots.Juiciness is a trait highly associated with resilience.That's why it is so present in plants that inhabit arid regions of the globe, because the lack of water is the biggest factor that prevents the survival of a plant.This incredible mechanism allows succulents to be found in Brazil, inhabiting from the rocks in Rio Grande Sul to the Amazon rainforest.It is estimated that there are more than 12,000 species of succulents distributed mainly in southern and eastern Africa, in the Andes, Brazil, Mexico and the deserts of North America.However, these plants only occur in very restricted places, which makes most succulents very susceptible to habitat loss and climate change and, as a consequence, many are threatened with extinction.If, on the one hand, global warming affects the survival of several succulents in their natural environments, on the other hand, these plants represent the future of agriculture.Like sugarcane, these plants have the ability to accumulate a lot of sugars that can be converted into biofuels, with the difference that they use up to 80% less water than traditional crops.About the stamps – The issue brings 4 stamps of succulents, of the species Okra-da-lapa (Uebelmannia pectinifera), Mandacaru (Cereus jamacaru), Pedra plant (Lithops lesliei) and Sisal (Agave sisalana), portrayed in beautiful photographs, where it is possible to see the beauty of the colors, textures and formats of the Brazilian flora.Uebelmannia pectinifera subsp flavispina (Buining & Brederoo)One of the rarest cacti of the Brazilian flora, being found only in the rocky fields of the Espinhaço Range in Minas Gerais.The subspecies with yellow spines is even rarer and is only native to the municipality of Diamantina-MG.Lithops lesliei (NEBr.)A plant native to desert regions in Namibia and South Africa, it has numerous morphological and physiological adaptations to thrive in extreme environments.This succulent mimics stones and thus avoids being preyed upon.It is estimated that there are around 300 species of Lithops, distinguished by the different patterns of their leaves.One of the most typical cacti in the Brazilian semiarid landscape, which can exceed 10m in height.It is found from Piauí to Minas Gerais, but it can be cultivated in practically all of Brazil.It has already been widely used in civil construction and now stands out for its biotechnological potential in the cosmetics and food industry.Native to the Mexican semi-arid region, this plant produces a fiber known as Sisal in Brazil.Obtained from the leaves of Agave sisalana, its cultivation is of great importance, being often the only alternative with economic gains in the Brazilian semiarid region.Today, Sisal is used mainly in rope making and its bagasse has shown potential for bioinsecticides, mannocellulose and even biogas.With a print run of 128,000 copies and a value of R$ 2.60 each, the stamps are now available for sale in the virtual store and, soon, in the main agencies in the country.Topics: POST OFFICE, TRIBUTE, TOCANTINSEmerged is news, entertainment, sports, promotions, politics, curiosities© 2008-2022, Emerged.All rights reserved.
