(Greek, lip-flower, alluding to the indusium). Polypodiaceae. Semi-hardy or hothouse ferns of small size.

Plants often hairy or woolly, with the sori terminal on the veins and covered with a roundish indusium. - Some 60 or 70 species are known, nearly a third of which are natives of the W. and S. W. United States, one species as far east as Conn. They are of easy cultivation, enjoying a position near the glass, and disliking strong, close heat and syringing or watering overhead. Most of the species grow naturally in dry rocky situations. They are among the few ferns to be found in dry regions. Commercially valuable only from the fern collector's standpoint.

A. Leaves pentagonal-deltoid, the indusium confined to a single veinlet. 1. californica, Mett. (Hypolepis californica, Hook.). Leaves densely cespitose from a short creeping rootstock,

2-4 in. each way, on stalks 4-8 in. long, quadripinnatifid; ultimate segments lanceolate, incised or serrate. Calif.

2. Meifolia, D. C. Eaton

(Hypolepis meifolia, Baker). Leaves cespitose, with slender brown stalks 5-7 in. long, the lamina 2-3 in. each way, 3-4-pinnatifid, with finely cut segments 1/10in. wide. Mex.

AA. Leaves lanceolate or ovate-lanceolate.

3. segments flat: indusia extending over the apices of several veinlets, but not continuous.

c. Surface of leaves smooth.

3. Microphylla, Swartz

Leaves 4-10 in. long, on stalks nearly as long, from a short, creeping rootstock, bi-tripin-nate: stems glossy, rusty-pubescent on the upper side. Fla. and New Mex. southward.

cc. Surface of leaves viscid-glandular.

4. Viscida, Davenport

Leaves 3-5 in. long, on stalks of the same length, tripinnatifid; segments toothed, everywhere glandular. Calif.

ccc. Surface of leaves hairy, not woolly.

5. Hirta, Swartz

Leaves densely cespitose, with short, scaly stalks which are brownish, like the rachides; pinnae numerous, rather distant bipinnatifld, the segments with much incurved margins. The leaves are usually 6-15 in. long. Cape of Good Hope. variety Ellisiana, is more commonly cultivation.

6. Lanosa, Wats

(C. vestita, Swartz). Fig. 900. Leaves cespitose, with stalks 2-4 in. long, slightly hairy, as are the segments, tripinnatifid, 4-10 in. long, 1-2 1/2 in. wide, the pinnae lanceolate-deltoid: indusia formed of the ends of roundish or oblong lobes. Conn, to Kans. and Ala. - Hardy.

Cheilanthes lanosa.

Fig. 900. Cheilanthes lanosa.

7. Codperae, D. C. Eaton

Leaves 3-8 in. long, bipin-nate, the stalks covered with nearly white hairs, each tipped with a gland; pinnules roundish ovate, crenate and incised. Calif, to Mex.

bb. segments bead-like, minute: indusia usually continuous.

c. Leaves hairy or woolly beneath, but not scaly.

D. Upper surface of segments smooth.

8. Gracillima, D. C. Eaton

Lace Fern. Leaves cespitose, 1-4 in. long, borne on the nearly equal dark brown stalks, bipinnate; pinna) with about 9 pinnules, finally smooth above. Idaho to Calif. - Hardy

9. Clevelandii, D. C. Eaton

Leaves 4-8 in. long, tripinnate, dark brown beneath, with closely imbricate, ciliate scales, which grow on both the segments and the rachides; segments nearly round, the terminal larger. Calif.

dd. Upper surface of segments pubescent.

10. Tomentfisa, Link. Lvs

8-15 in. long, on stalks 4-6 in. long, everywhere covered with brownish white hairs, tripinnate; terminal segments twice as large as the lateral. Va. to Ariz.

cc. Leaves covered beneath with scales, but not woolly.

11. Fendleri, Hook

Leaves 3-6 in. long, borne on the chaffy stalks, rising from tangled, creeping rootstocks, tripinnate; rachis with broadly-ovate white-edged scales, which overlap the subglobose segments Texas, and Colo, to Calif.

ccc. Leaves covered beneath with both scales and wool.

12. Myriophylla, Desv

(C. elegans, Desv.). Leaves densely cespitose from short, erect, scaly rootstocks, 3-9 in. long, borne on the chestnut-colored scaly stalks, triquadripinnatifid; ultimate segments minute, innumerable. Texas, Ariz, and tropical Amer.

A native species worthy of cult, is C. leucopoda, Link, from Texas, with broadly deltoid-ovate lvs-C. undulata, Hope & Wright. Dark green fronds, softly pubescent. China. G.C. III. 34:397 (dew.) L .M Underwood.
