Deciphering species relationships and hybrid origins in polyploid agamic species complexes is notoriously difficult. In this study of cheilanthoid ferns, we demonstrate increased resolving power for clarifying the origins of polyploid lineages by integrating evidence from a diverse selection of biosystematic methods. The prevalence of polyploidy, hybridization, and apomixis in ferns suggests th...

The indigenous communities of Shishikoh valley are often using various ferns taxa regularly. current research work was intended for documenting the ethnomedicinal knowledge ferns. A total 18 were recorded that belonged to 9 genera and 6 families being used in treatment different ailments. Pteridaceae leading family with (33.33%), followed by Aspleniaceae 4 (22.22%), Athyriaceae Equisetaceae eac...

Arsenic uptake by plants is species-specific and its level in terrestrial of uncontaminated sites ranged from 0.009 to 1.5 mg/kg. Plants with high metal or metalloid capability their biomass are called hyperaccumulators. The most efficient arsenic (As) hyperaccumulator belongs Pteridaceae species Pteris vittata L. Pityrogramma calomelanos L., both can accumulate more than 8000 mg/kg As above-gr...

Aquatic macrophytes are a key group in flooded areas due to their high primary productivity, and several species present the Amazonian floodplains have potential for human food use. This study evaluated biomass production nutrient levels fronds of Ceratopteris pteridoides (Pteridaceae), under following nutritional treatments: (T1) artesian well water, (T2) natural lake (T3) water with nutritive...

Adiantum meishanianum is an endemic species distributed only in Meishan village, Kaohsiung, Taiwan. Because its sporangia contain only abortive spores, A. meishanianum has been regarded as having a hybrid origin, presumably with A. caudatum, A. malesianum, and A. philippense as the putative parents. The aim of this study is to confirm the hybrid origin and determine the parental lineages of A. ...
