Scientific literature: Very Sparse (0 studies) · ★☆☆☆☆
Marsilea is a fascinating genus of aquatic ferns that thrives in wetland environments across the globe. These unique plants are characterized by their four-leaf clover-like appearance, which distinguishes them from many other aquatic species. As they grow in nutrient-rich soils, they play a vital role in managing the presence of minerals such as arsenic within their ecosystems. Their ability to adapt to fluctuating water levels makes them resilient survivors in various marshy habitats. Understanding their biological processes provides valuable insight into how aquatic vegetation interacts with chemical elements in the water.

Conditions
Marsilea serves as a highly effective candidate for the phytoremediation of arsenic-contaminated paddy fields. Among the aquatic plants studied in West Bengal, this fern species demonstrated the highest Specific Arsenic Uptake with an average of 45 mg kg⁻¹ dw. This significant capacity to accumulate arsenic through ionic mimicry positions it as a valuable tool for environmental cleanup. While other aquatic species like Eichhornia crassipes and Cyperus difformis also show promise, Marsilea stands out due to its superior uptake levels. Consequently, utilizing this plant can help mitigate the widespread threat of arsenic pollution in local agricultural ecosystems.
