“…Many of these species are at risk of extinction, with 45 classified as "Critically Endangered", 67 "Endangered" and 21 "Vulnerable" It has already been possible to collect some extremely rare species and record new occurrences for some Brazilian states. In the last 3 years, 17 new species and 1 genus were described for Science (Leme et al, 2020;2022;Cavalcante et al, 2021;2022;Pontes et al, 2021;Souza et al, 2021a;2021b;2021c;2022a;2022b;Leodegário et al, 2022).…”

Brazilian floriculture is driven by novelties, requiring the constant entry of new products into the market. This situation favors Brazil, which has, in its native flora, unique species in the world and with high potential for rational use for commercial purposes. The Brazilian flora with ornamental potential is little explored, and the use of species is restricted and, often, extractive with consequent genetic erosion. The use of native species from different ecosystems may constitute a future alternative of products for Brazilian floriculture. Despite the large amount of plant genetic resources, there are few initiatives for the conservation and domestication of species and improvement for sustainable use. For this reason, the Brazilian Agricultural Research Corporation (Embrapa) conserves collections of ornamental plants, and the research initiatives of these collections form the Genetic Resources of Ornamental Plants Project. In addition to conservation, it sought, in partnership with other institutions, the characterization and evaluation of the potential use of these species aiming at the completion of products for floriculture. In this way, the materials already characterized and documented make it possible to add value to genetic resources, already maintained. Currently, Embrapa has six ex situ collections of ornamental plants (Tropical species, Bromeliads, Cactaceae and species from the Pampa Biome, Amazonian Orchids and species from Cerrado) and also counts on the genetic variability of banks of other products (Passion fruit, Pineapple, Paspalum, Pepper, Pumpkin germplasm banks) that have been evaluating accessions, selecting and registering cultivars for ornamental use.

“…Tillandsia is a genus of Bromeliaceae [ 1 , 2 ] with epiphytic, atmospheric terrestrial, and saxicolous plants [ 3 , 4 ]. In recent years, several new species have been described [ 5 , 6 , 7 ], and some anatomical adaptations have been studied that make it successful in the difficult environment of the Atacama Desert [ 8 ].…”

In the extreme north of Chile, the genus Tillandsia L. (Bromeliaceae) is represented by three native species, T. marconae Till & Vitek and T. landbeckii Phil., both of terrestrial atmospheric habit, and T. virescens Ruiz & Pav. of saxicolous habit. There is little information on the foliar structures that allow its establishment in arid environments. Therefore, we studied the leaf anatomy of each of these terrestrial and saxicolous atmospheric species from different altitudinal levels (1000 and 3000 m) in the Arica and Parinacota regions of the Atacama Desert. All populations are monospecific. The study considered scanning electron microscopy, optical microscopy, and the fingernail polish technique. The surface distribution of stomata and trichomes of the species is described. The studied species presented hypostomatic leaves, with anomocytic stomata and peltate trichomes on the abaxial and adaxial sides. Trichomes are formed by a central disc of four equal-sized empty cells, surrounded by a peripheral series of several concentric rings, the innermost of eight, the second of sixteen and the outermost of multiple elongated cells, one cell thick, that form the flexible asymmetric wings. The number of wing cells varies according to the species. Trichomes are evenly arranged in long lanceolate leaf blades with smooth margins.
