General Comments:Many spleenworts are rare. Please do not harvest from the wild. Most spleenworts have very narrow ranges and narrow environmental tolerances. Don't confuse with the invasive tuberous sword fern Nephrolepis cordifolia--if the fern spreads via rhizomes and is abundant, it's probably the sword fern.
