182 MACOUN AND BUEGESS ON 



Like P.falcatum, this fern is in Canada restricted in its range to British. Columbia, speci- 

 mens collected in which province, at Alberni on the western side of Vancouver Island, by 

 Mr. J. R. Anderson, have been kindly furnished for examination by Mr. Jas. Fletcher, of 

 Ottawa. Vancouver Island and main land west of Coast Range. — Mucoun. 



Genus II.— GYMNOGRAMME, Desv., Gold-Fern. 



1. — GYMNOGRAMME TRIANGULARIS, KaulJ., (California Gold-Fern or Gold-back). Hook., 

 Fl. Bor.-Am., II, 259. Macoun's Cat., No. 2285. Eaton, Ferns of N. A., II, 15. Under- 

 wood, Our Nat. Ferns, etc., 82. 



This handsome evergreen fern, varying from 5 to 15 inches in height, grows on hill- 

 sides in the crevices of rocks. Rootstock short, creeping, chaffy and covered with old 

 stalk-bases ; stalks slender, dark brown, polished, and densely tufted ; fronds pinnate, 

 deltoid or pentagonal in outline, measuring from 1J to 5 inches each way ; lower pinnae 

 much the largest, triangular, and twice parted, with the secondary pinnae much elongated 

 on the lower side ; upper pinnse lanceolate, and more or less pinnately lobed ; upper sur- 

 face of the fronds smooth or rarely minutely granular, but beneath they are covered with 

 a yellow or white ceraceous powder. 



Specimens examined display no variation, except that British Columbian plants are 

 rather more rigid and stunted in growth than those from California. Var. viscosa, D.C. 

 Eaton, a Californian form, has the upper surface of the fronds viscid. 



Though common enough in the United States, from California to Oregon, this fern in 

 the Dominion grows only in British Columbia, and is of rare occurrence even there.

Genus III— CHEILANTHES, Swz., Lip-Fern. 



1. — C. gracillima, D. C. Eaton, (Lace-Fern, Graceful Lip-Fern), Hook, and Baker, 

 Syn. Fil., 139. Eaton, Ferns of N. A., II, 247. Underwood, Our Nat. Ferns, etc., 90. 



C. vestita, Brackenridge. 



An evergreen plant, 3 to 10 inches high, growing in dense beds among rocks. Root- 

 stocks creeping, tangled, chaffy ; stalks tufted, dark brown, scaly when young but soon 

 becoming smooth ; fronds about half as long as the stalks, linear-oblong in outline, bipin- 

 nate or sometimes, from the lobing of some of the pinnules at the base, partly tripinnate ; 

 pinna; numerous, crowded, and composed of about nine oblong-oval pinnules, which are 

 about a line in length and smooth or very nearly so above, but clothed with pale, ferru- 

 ginous, matted wool beneath ; indusia rather broad, yellowish-brown, and formed of the 

 continuously recurved margin of the pinnules. 



Among British Columbian specimens supplied by Mr. Fletcher, and found growing 

 with the common form, were some fronds differing from those figured in the "Ferns of 

 North America," in being markedly more slender, with distant pinnse and smaller and 

 more distant pinnules. 



This is another British Columbian species reported only from Mount Finlayson, 

 near Victoria, Vancouver Island. — J. Fletcher. Crevices of dry and exposed rocks a few
