“…The plants were greatly affected by the coal gangue in both species richness and abundance. In the area of or near former coal mines (GP and CK-near), plants like M. floridulus 23 and H. punctate 24 , which live readily in moist areas, and show characteristics of drought-tolerance and acidic soil-resistance, became the dominant species.…”

coal gangue piles accumulate outside mines and can persist for years, negatively impacting the regional environment. to determine the main cause of soil pollution at coal gangues, several coal gangues in Guizhou Province, China that had undergone natural recovery via native plants for 8 years were investigated in summer 2019. Three plots (2 m × 2 m) from the coal gangue area were selected for the treatment (GP). Control plots that were 100 m away from GP were also investigated in contrast (CK-near). In addition, plots from forest, farmland and lake land that were far from GP and largely undisturbed were also investigated as more extreme contrasts (CK-far). A series of soil indicators that can be affected by coal-gangue, such as heavy metals (Mn, Cr, Cd, Ni, Zn, Cu, Pb), As, pH, cation exchange capacity (CEC), sulfur (S) and iron (Fe), were tested for in the plots. Plant species, coverage and height were also analyzed to uncover biodiversity and dominant species information. the results suggested that coal gangue significantly influences soil S, pH and plant species after 8 years of natural recovery. The CK-far plots contained relatively low soil sulfur content, normal pH (close to 7) and abundant plant biodiversity. Generally, pH related positively with both the Patrick (R = 0.79, n = 22, p < 0.001) and Shannon indices (R = 0.67, n = 22, p < 0.001); the soil S related negatively with both the Patrick (R = 0.85, n = 22, p < 0.001) and Shannon indices (R = − 0.79, n = 22, p < 0.001). S content was highest (S = 1.0%) in GP plots, was lower in CK-near plots (S = 0.3%) and was the lowest of all in the plots distant from the coal mine (S = 0.1%, CK-far). S content was negatively correlated with pH. Soil pH decreased significantly, from 7.0 in CK-far, to 5.9 in CK-near, to 4.2 in GP. Soil Fe was 3.4 times higher in GP and CK-near than in CK-far. The excess sulfur and Fe elements and the acidified soil drove changes in soil and vegetation in the coal gangue areas. After 8 years of natural recovery, only a few plants, like Miscanthus floridulus, were able to live near the coal gangue in the area where the soil was still acidic and high in S and fe. Coal mining is indispensable due to the widespread use of coal, and gangue is the accumulated solid waste byproduct that persists in mined lands, even after the mines have been abandoned 1. In the past 2 decades the growth of the coal mining industry has resulted in large amounts of accumulated coal gangue in China 2,3. Guizhou's annual coal output reached 139.17 million tons in 2018, ranking the fifth in China. Due to the extensive resource-based production mode, the coal industries here have caused serious environmental pollution and resource waste. Coal gangue contain various harmful components, such as heavy metals like Pb, Cd, Cr, Cu, Zn, Hg, Ni, Mn and As, which accumulate in nearby soils 4,5. Due to natural processes like efflorescence, sun exposure, rain leaching, the release of heavy metals and other elements, gangue readily affects the surrounding environment, includi...

“…Thus, we took into account recent reports of new species or occurrences of fern and lycophyte species published since Roux (2009) such as a compilation of Pteridaceae of Togo (Abotsi et al, 2015), ferns from the Saharan Mountains (Antheme et al, 2011), invasion of South Africa by the water fern Azolla Lam. (Madeira et al, 2016), pteridophytes of Madagascar (Rakotondrainibe & Jouy, 2016a, 2016b, or various taxonomic revisions, new species descriptions, or new records (e.g., Fischer et al, 2010;Roux, 2011Roux, , 2012Hemp, 2012;Dubuisson et al, 2013Dubuisson et al, , 2016Schwartzburd & Prado, 2014;Jongkind & de Winter, 2015;Widen et al, 2015). We also consulted floras published in the last ten years including the pteridophyte treatments published in the Tropical Flora of East Africa and online flora resources (Table 1).…”

In this review, we explore our current understanding of the fern and lycophyte diversity occurring in the Eastern Afromontane Biodiversity Hotspot (EABH). The review explores the species diversity of this region in the context of the Afromadagascan pteridophyte diversity based on an exhaustive species list assembled in the synopsis of Afromadagascan pteridophytes published by Roux in 2009. The list was updated by incorporating recent progress in our understanding of the taxonomy and phylogeny of these plants. Evidence for a distinct pteridophyte flora occurring in the East African mountain region was discovered using ordination and clustering analyses. This EABH floras shares links to other Afromadagascan pteridophyte floras such as the one in the tropical lowland forests of central and western Africa. These floras share the dominance of species that preferably occur in humid climates whereas other African pteridophyte floras tend to contain a higher proportion of xeric adapted ferns. The phylogenetic composition of the EABH pteridophyte flora was assessed by comparing global versus local proportion of orders, families, and genera. This analysis revealed distinct patterns that are partly caused by the radiation of Blotiella and Triplophyllum besides selective colonization of species pre-adapted to Afromadagascan climates. In situ speciation in the East African tropical mountains may have contributed to the global diversity of widespread genera such as Asplenium and Pteris. In summary, this is the first comprehensive attempt to assess the pteridophyte diversity of the East African mountains providing the framework for future studies on their conservation, ecology, and evolution.

“…those works indicate the occurrence of two species: the southern H. poeppigii (Kunze 1834: 50) Mettenius ex Maxon (1941: 289) and the northern H. repens (linnaeus 1753: 1078) Presl (1836: 162). then, Schwartsburd (2012a) and Schwartsburd & Prado (2014) showed these two names were misapplied: while the southern species is best classified as H. poeppigiana Mettenius (1856: 18)-which they regarded a subspecies of the sub-cosmopolitan H. rugosula (labillardière 1806 [1807]: 92) Smith (1846: 8): H. rugosula subsp. poeppigiana (Mett.)…”
