The currently known species of are herbs, shrubs, small trees and vines. After 20 years without new species of in Mexico, here is described and illustrated the first epiphytic species in the genus. The species was found growing on trees of the cloud forests from central Veracruz in eastern Mexico. It is known and described from very few specimens in the type locality. The most morphologically similar Mexican species are the vines and , it was compared. Conservation assessment classifies this species under the Critically Endangered CR B1+B2ab(ii,v) category of the IUCN Red List Criteria.

Despite the increasing number of studies investigating tree methane fluxes, the relationships between tree methane fluxes and species traits remain mostly unexplored. We measured leaf and stem methane fluxes of five tree species (Acer saccharinum, Fraxinus nigra, Ulmus americana, Salix nigra, and Populus spp.) in the floodplain of Lake St-Pierre (Québec) and examined how these fluxes vary with species traits (wood density, humidity, pH; leaf water content, pH, stomatal conductance; methanogen and methanotroph relative abundances (RAs) in leaf, wood, and bark).

Dendrobium officinale(DO) is a traditional Chinese medicinal and edible plant, while it is critically endangered worldwide. This article, primarily based on the original research findings of the author's team and available articles, provides a comprehensive overview of the factors contributing to the endangerment of DO and the key technologies for the conservation, efficient cultivation, and value-added utilization of this plant. The scarcity of wild populations, low seed-setting rates, lack of endosperm in seeds, and the need for symbiosis with endophytic fungi for seed germination under natural conditions are identified as the primary causes for the rarity and endangerment of DO.

Two new species of are described based on recent field expeditions and herbarium research. These species are unusual within for exhibiting a dorsiventral epiphytic habit typical of many northern Andean species, but they lack conspicuous floral bracts. Lozano-Cif.

Background: is a genus in the Ericaceae comprising, approximately 50 species and is distributed from Venezuela and Guyana to northern Peru in South America. The country with the greatest diversity of the genus is Ecuador, where most taxa are restricted to the submontane and montane forests of the eastern slopes of the Andes. The " group" refers to a set of species restricted to south-eastern Ecuador, characterised by plants with an epiphytic and pendant habit, amplexicaul leaves that partially enclose the flowers, few-flowered inflorescences provided with small floral bracts and bracteoles and a calyx with a non-prominent limb.

Background: Reproductive isolation mechanisms in flowering plants are fundamental to preserving species' evolutionary independence and to enabling the local coexistence of closely related species. These reproductive barriers are expected to contribute to maintaining local diversity of highly diverse plant guilds, such as bromeliads in neotropical ecosystems. We evaluated how strong and effective these barriers are by analyzing different mechanisms that act before and after pollination in a guild of four epiphytic bromeliads from the genus (Tillandsioideae) pollinated by bats in a Costa Rican montane forest.
