Myriopteris lanosa (Michx.) Grusz & Windham

국표에 없다.

Myriopteris lanosa, the hairy lip fern, is a moderately-sized fern of the eastern United States, a member of the family Pteridaceae. Its leaves and stem are sparsely covered in hairs, but lack scales, hence its common name. One of the cheilanthoid ferns, it was usually classified in the genus Cheilanthes until 2013, when the genus Myriopteris was again recognized as separate from Cheilanthes. It typically grows in shallow, dry, soil, often in rocky habitats.

Description

Leaf bases are closely spaced along the rhizome, which is generally 4 to 8 millimeters (0.2 to 0.3 in) in diameter and rarely branched. The rhizome bears persistent scales, which are linear to slightly lanceolate, distantly toothed, straight or slightly twisted, and loosely pressed against the surface of the rhizome. Most of them are brown in color, but at least a few will show a thin, dark central stripe, which does not stand out well from the rest of the scale color.

[잎 기저부는 뿌리 줄기를 따라 밀접하게 이격되어 있는데, 일반적으로 지름이 4 ~ 8 밀리미터 (0.2 ~ 0.3 인치)이며 거의 분지되지 않습니다. 뿌리 줄기는 선형에서 약간 피침 모양, 멀리 치형, 직선 또는 약간 비틀어 진 뿌리 줄기의 표면에 느슨하게 밀착되는 지속적인 비늘을 가지고 있습니다. 대부분은 갈색이지만, 적어도 몇 개는 얇고 어두운 중앙 스트라이프를 보여줄 것이며, 이는 나머지 스케일 색상과 잘 어울리지 않습니다.]

The fronds spring up in clusters and emerge as fiddleheads (circinate vernation). When mature, they are 7 to 50 centimeters (2.8 to 19.7 in) long and 1.5 to 5 centimeters (0.59 to 1.97 in) wide. Fertile and sterile fronds are similar in appearance. The stipe (the stalk of the leaf, below the blade) is 3 to 18 centimeters (1.2 to 7.1 in) long. It is dark brown to purplish-black in color, with many long, persistent, dark-jointed hairs. The upper surface is rounded.

The leaf blades range in shape from lanceolate to linear-oblong. The blade is usually bipinnate-pinnatifid (cut into pinnae and lobed pinnules) at the base. Each blade is cut into 12 to 20 pairs of pinnae. The rachis (leaf axis) is rounded on the upper side, dark in color, and bears soft hairs of uniform shape, but not scales. The pinnae are not jointed at the base, and the dark pigmentation of the rachis enters the edge of the pinnae. The pinnae at the base of the leaf are slightly smaller than the pinnae immediately above them, and the pinnae are more or less symmetric about the costa (pinna axis). The upper surfaces of the pinnae are sparsely covered with hairs. The upper sides of the costae are brown for most of their length and lack scales. The pinnules are lanceolate or oblong, and not bead-shaped as in some other species of Myriopteris. There are 7 to 14 pairs of pinnules per pinna. The largest pinnules are 3 to 5 millimeters (0.12 to 0.20 in) long, with a sparse covering of long, segmented hairs on both upper and lower surfaces.
