Lindheimer's lipfern

Leaf bases are widely spaced along the long-creeping rhizome, which is about 1 to 1.5 millimeters (0.039 to 0.059 in) in diameter. It bears scales 1 to 2 millimeters (0.04 to 0.08 in) long, which are lanceolate to ovate-lanceolate, straight or slightly twisted, and loosely pressed against the surface of the rhizome. They are thin to hardened in texture, of a uniform tan to brown color, and their margins are entire (without teeth or lobes). They may sometimes have a dark brown central stripe contrasting with pale brown to reddish-brown margins. Some of the older scales may be shed from the rhizome. The fronds arise individually from the rhizome, typically spaced 3 to 20 centimeters (1 to 8 in) apart. Unlike many ferns, they do not emerge as coiled fiddleheads (noncircinate vernation). When mature, they are 7 to 30 centimeters (2.8 to 11.8 in) long. The stipe (the stalk of the leaf, below the blade) is 4 to 19 centimeters (1.6 to 7.5 in) long. and typically about one-third to one-half of the total length of the frond. Myriopteris lindheimeri grows in dense colonies from a long creeping rhizome with brown scales. Leaves are generally lanceolate and 7–30 cm long and 2–5 cm wide with a dark brown petiole. The leaf blade is 4-pinnate at the base, grayish or silvery green on top and covered with rusty brown wooly hairs below. …

Myriopteris lindheimeri is native to southwestern United States and northern Mexico. It grows on rocky slopes and ledges, on a variety of acidic to mildly basic substrates, at elevations from 200 to 2,500 m (660 to 8,200 ft).

Myriopteris lindheimeri can be relatively easily cultivated, and should be grown under high light in well-drained garden soil. The soil should be dry to moist-dry.
