Crude Drug Identification

Properties of Crude Drugs

The rhizome is thick and short, densely covered with black, linear-lanceolate or awl-shaped scales. The leaves are pale green and leathery; the petioles are 5–10 cm long and slender; the leaves are three-times pinnately compound, with triangular-oblong leaflets that are broader at the base; the pinnae are ovate; the ultimate segments are linear with 1–2 fine teeth; both surfaces are glabrous.

Botanical Information

Botanical Classification

A plant of the family Dryopteridaceae: Central Chinese Dryopteris.

Morphological Characteristics

The plant grows to a height of 10–23 cm. The rhizome is short and erect, densely covered with scales at the apex; the scales are narrowly lanceolate, 3–3.5 mm long, thickly membranous, blackish-brown, glossy, and with minute teeth along the margins.Leaves are clustered; petioles are 5–10 cm long, 0.5–1 mm thick, pale green, nearly smooth or slightly covered with one or two small, brown, fibrous scales, with shallow, broad longitudinal grooves on the upper surface; leaf blades are elliptic, 5–13 cm long, 2.5–5 cm wide, and three-times pinnately divided;with 8–10 pairs of leaflets spaced 1–1.2 cm apart; the basal leaflets are more widely spaced, opposite, and become alternate toward the apex; they are obliquely spreading and have short petioles (0.5–1.5 mm long);the basal pair is the largest or equal in size to the second pair (occasionally slightly shorter), 1.5–3 cm long and 1–2 cm wide, ovate-triangular, with an acuminate or acute apex, an asymmetrical base—the upper side truncate and parallel to or covering the rachis, the lower side cuneate—and twice pinnately lobed;4–5 pairs of lobules, alternate, the upper pair emerging first, spreading obliquely; the upper lobule on the upper side is larger, 5–11 mm long, 4–7 mm wide, ovate, with an acute apex, the base symmetrically broadly cuneate and extending downward, deeply pinnately lobed to the rachis;There are 5–6 lobes, obliquely ascending, widely spaced, narrowly linear, 1.5–5 mm long, 0.5–2 mm wide; the basal pair is often 2–3-lobed, with 2–3 blunt- or sharp-tipped small teeth at the apex of the minor lobes, and each upper lobe bearing sharp teeth at the apex; the remaining minor lobes are smaller and widely spaced from one another.Veins are prominent on both surfaces; on the upper surface, they are raised. Secondary veins on the lobes are dichotomously or trichotomously branched; on the lobes at the base of the pinnae, they are dichotomously branched twice, slanting upward, and do not reach the leaf margin. Leaves are firm and herbaceous, turning gray-green when dry; the rachis and all order of pinnae are the same color as the petiole, with narrow, linear wings on both sides, and the rachis is markedly raised on both surfaces.Sporangia are nearly elliptical, 1–1.5 mm long, brown; there are 1–2 per lobe, slanting upward, borne on the upper part of the secondary veins, not reaching the leaf margin; indusia are of the same shape, gray-green, membranous, entire, opening toward the midrib, and persistent.
