338 FILICES. Uh'jUanlltcs. 



Bound. 234, and Ferns of the Southwest, 313. C. vesllta, IJrackeniidge, Ferns 

 of U. S. Fxpl. Fxped., not of 8\vaitz. 



In rocky places, mostly nt high elevations (0,000 to 8,000 feet), from the Yoscniite to Oregon, 

 by many collector.s ; also in IJiitish (.'olnmbia. Called " Lace Fein" hy visitors to the Yoseiiiile. 

 A single specimen from Bartlelt's Canon, near Santa Barbara, collected by Uvlhrock, is twice the 

 iisnal size, and I'nlly tripinnate. 



* * Fronds very scaly beneath, and sometimes sparhujly tomentose also. {Tlie 

 species of this (/roup are very perplexing, all much resemblinrf each other and 

 difficult to define. The most distinctive cliaracters are found in the rhizoma 

 or rootstock.) 



5. C. myriophylla, Desv. IJootstock short, ascendini,', often nodose, covered 

 with narrow dark-ltrown rigid scales : stalks clustered, 2 to G inches high, wiry, 

 castaneous, covered with partly decichious pale-cinereous narrow appressed scales and 

 paleaceous hairs : fronds 3 to 8 inches long, ovate-oblong or oblong-lanceolate, 

 smooth and green or deciduously j)il()se above, 3 - -i-pinnato ; rhachises and midribs 

 densely covered beneath with pale-brown or ferruginous ovate or ovate-lanceolate 

 ciliated scales ; pinnaj deltoid-ovate, narrower upwards ; idtimate segments minute 

 (half a line broad), roundish or roundish-pyriform, crowded, innumerable, sometimes 

 (especially those of sterile fronds) tliree-lobed or parted, covered bcmeatli with ovate 

 scales having few or many long tortuous cilia passing into branclied and entangled 

 hairs, tlie unchanged margin of the segments much incurved. — C. eltyans and 

 C. myriophylla, Desvaux in rjcrlin Mag. v. 328; Hooker, Sp. Fil. ii, 100 ami 102, 

 t. 105. C. viyriophylla, Hooker & I>aker, Syn. Fil. 140; Eaton, Ferns of the 

 Southwest, 31G. C. eleyans, Kuhn, Leitr. 8. C. j)aUacea, Martens & Galeotti, 

 Syn. Fil. Mex. 7G, t. 21, lig. 2. 



In crevices of rocks and on exposed rocks, mostly at elevations of 3,000 to 5,000 feet, from 

 Lake Connty sontliward in the Coast Ranges, and in the Sierra Nevada from Western Nevada to 

 San Bernardino County ; Sonth Pass of the Rocky Monnlains, Arizona and New Jlexico, and to 

 I'eru and Chili. This fern y)re.sents many forms, some with broad and bnt slightly ciliated scales 

 often passing for 0. Fcadkri, or recommended as probably distinct species by various authors and 

 collectors. 1 hav(! seen no genuine C. Fcndlcri from California, the jjlants fomicrly so called 

 being all forms of the juesent species. 



6. C. Clevelandii, Eaton. Eootstock cord-like, creeping, elongated, covered 

 with narrow rigid dark-brown scales : stalks scattered, 2 to 6 inches long, dark- 

 brown, at first bearing paleaceous hairs : fronds 4 to G inches long, ovate-lanceolate, 

 3-4-pinnate, smooth and greeji above, beneath everywhere deep fulvous-brown 

 (when mature) from the dense covering of closely imbricated ovate-acuminate elegantly 

 ciliate scales ; ultimate segments crowded, innumerable, flatfish, nearly rountl, sessile, 

 ^ to i a line broad, the terminal ones a little larger; margins mirrowly recurved and 

 unchanged in texture. — Torr. Bot. bulletin, vi. 33, and Ferns of N. Amer. i. 81), 

 t. 12, lig. 2. 



In loose sandy soil and at the base of rocks, among the mountains of San -Diego Connty {D. 

 Cleveland, IV. SloiU) ; also in the Peninsula of Lower California, J. Schott. The rootstock is 

 nearly as thick as a goose-(|uill and several inches long. The scales are at first white, but gradu- 

 ally turn to a rich chestnut-brown. Specimens recently received conlirm the sjieeies. 



5. PELL.ffiA, Link. Ci.ikf-Buake. 

 Sori roundish or oblong, placed near the ends of the veins, often continent in a 

 submarginal band : involucre membranaceous, often broad, continuous round the 

 Ijinnules, and formed from their reflexed margin. Sterile and fertile fronds much 

 alike, 1 - 4-pinnate, generally smooth and sometimes glaucescent. Stalk usually 

 dark-colored. 



A genus of about f.O species, none of them large ferns. Eleven species occur in the United 

 States, 11 few more in tropical America, ami a good many in South Africa. The genus is closely
