The plant usually grows to a height of 45-90- (120) centimeters. The rhizome runs horizontally, about 2 millimeters thick, densely covered with dark rust-colored hairs. The leaves are distantly spaced, with petioles 24-56 centimeters long, 1.5-2 millimeters thick, brownish straw-colored, smooth, and hairless above the base; the leaf axis branches once or twice (three times), with the primary rachis about 9 centimeters long, covered with dark rust-colored hairs, gradually becoming smooth, sometimes with a terminal bud sprouting, producing a primary rachis 6.5-17.5 centimeters long, and a secondary rachis 3-5 centimeters long; the axillary buds are small, ovate, densely covered with rusty yellow hairs; the bud scales are 5-7 millimeters long, ovate, with irregularly serrated edges or coarse teeth, occasionally entire; at each branching point, there are a pair of leaf-like pinnules on both sides, spreading, broadly lanceolate, equal or unequal in size, those at the first branching point are 9.5-16.5 centimeters long and 3.5-5.2 centimeters wide, and those at the second branching point are smaller, 4.4-11.5 centimeters long and 1.6-3.6 centimeters wide; the terminal pinnules are 16-23.5 centimeters long, about 4-5.5 centimeters wide, lanceolate or broadly lanceolate, tapering towards the apex, tail-like, with the upper side narrowing at the base, deeply lobed almost reaching the rachis; the lobes are spreading, 35-50 pairs, linear-lanceolate, 1.5-2.9 centimeters long, 3-4 millimeters wide, blunt at the tip, often slightly concave, with several pairs of very short, triangular or oblong-triangular lobes on the upper side at the base of each lobe, converging at the base of the lobes, with pointed notches, entire margins, and cartilaginous narrow edges. The lateral veins are prominent, raised on both sides, obliquely spreading, with 3-4 (5) parallel minor veins in each group, extending straight to the leaf margin. The leaves are papery, yellow-green or green on the upper surface, rust-colored hairs along the rachis, later becoming hairless, and grayish-white on the lower surface, sparsely covered with rust-colored hairs along the midrib and lateral veins. The sori are circular, in a single row, borne at the bend of the upper side or on both sides of the minor veins, consisting of 5-8 sporangia. Distribution area.

以分株为主病虫防治
The main method of disease and pest control is division and propagation.

于春季新叶抽生前将带有2～3片老叶的根茎切断，栽植后，另成新株。穴内施以基肥，栽后充分浇水。待抽生新叶后，任其生长。
In the spring, before the new leaves sprout, cut off the rhizome with 2-3 old leaves, and plant it to grow into a new plant. Apply base fertilizer in the planting hole and water thoroughly after planting. Allow the new leaves to grow freely after they sprout.
