Dryopteris macrophylla
The plant height can reach more than 1 meter. Rhizomes are stout and erect, densely covered with reddish brown or brown, lanceolate and narrowly lanceolate scales.
Dryopteris crassipes
The scales on the leaf axis are obviously twisted, linear to lanceolate reddish brown, and the petiole is dark straw color, which is obviously shorter than the leaves.
Check Baidu to see if it's these two kinds.
