 stipe, but more or less tomentose ; texture subcoriaceous, upper surface naked, 

 very convex in the mature, fertile frond, under surface tomentose like the rachis; 

 sori marginal. — Hk. Sp. 2. p. 92, t. 102. A. 



Hab. Cape Colony; discovered by M. Drfege. — It resembles C. hmugmosa and JSsontzii 

 in size and general appearance, but is naked on the upper surface, and not at all matted 

 beneath.

 chesnut-brown, thinly clothed with spreading woolly hairs'; fi: 4-8 in. 1., 

 7-1^ in. br., ovate-lanceolate, bipinnatifid ; pinnce in opposite pairs, the lower 

 ones deltoid ; pinnl. linear-oblong, contiguous, cut down to the rachis into 

 numerous small roundish or oblong segm. ; rachis tomentose ; texture sub- 

 coriaceous ; upper surface grass-green, slightly tomentose ; lower surface densely 

 matted with a coat of pale-brown woolly tomentum, the margin of the segm. 

 much incurved; sori copious, marginal. — C. lanosa, Moore. C. vestita, HL Sp. 

 2. p. 99. C. gracilis, Siehl, FSe, Gen. Fil. 149, oldest name. 



Hab. lUinoia and Wisconsin westward and southward to the Rooky Mountains, Cali-

 chesnut-brown, thinly coated with spreading woolly hairs, mixed with linear 

 scales ; /r. 3-6 in. 1., 1-1^ in. br., ovate-lanceolate, .bipinnatifid ; pinnce in 

 opposite pairs, the lower ones deltoid ; pinnl. linear-oblong, contiguous, cut 

 down to the rachis below into small roundish beaded segm. ; rachis scaly and 

 tomentose like the stipe ; texture subcoriaceous ; upper surface green, slightly 

 tomentose ; lower surface densely matted with a coat of pale-brown woolly hairs, 

 the margin of the segm. much incurved ; sori copious, marginal. — Sh. Sp. 2. 

 p. 98. t. 98. C. fimbriata, Visiani. C. persica, Mett., oldest name. 



Hab. Asia Minor and Persia southward to N. Hindostan, ascending in the Himalayas 

 to 8,500 ft., Italy and Dalmatia. — Very near 0. lanuginosa, from which it only differs 

 by having distinct scales mixed with the tomentum upon the stipes and rachis. Notho- 

 Iwna persica, Bory, is this species.

 1 in. br., narrowly ovate-lanceolate, bi- or tripinnatifid ; lower pinnce opposite, 

 lanceolate-deltoid, about J in. 1., ^ in. br., cut down to the rachis into several 

 lineax'-oblong segm. on each side, the largest of which are J in. L, and the lowest 

 again slightly divided ; texture subcoriaceous ; rachis slightly iibrillose ; upper 

 surface naked, the lower densely matted with pale-brown woolly tomentum, the 

 margin of the segm. much incurved ; sori copious, marginal. — Eaton in Report

Hab. British Columbia, Oregon, California, Missouri, New Mexico, Guatemala. — A

 lanceolate-deltoid, about J in. ]., f in. br. ; pinnl. linear-oblong, cut down to the 

 rachis into numerous small oblong beaded segm. ; rachis densely clothed above 

 with lanceolate acuminate entire scales, which are bright reddish-brown in the 

 centre, silvery- white towards the edge ; upper surface quite naked, under surface 

 scaly only, not matted ; texture subcoriaceous, margin much incurved ; sori
