Hab. Cape Colony ; discovered by M. Diege. — It resembles C. lanuginosa and Szovifzii 

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

 beneath.

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

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

 coriaceous ; 7ippcr surface grass-green, slightly tomentose ; lower surface densely 

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

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

 scales; //'. 3-0 in. I., 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. — Hk. 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 C. lanuginosa, from which it only differs 

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

 Ice na persica, Bory, is this species. 



40. C. gracillima, Eaton ; st. densely tufted, 2-G in. 1., wiry, slender, dark 

 chesnut-brown, polished, only slightly scaly towards the base ; fr. 3-4 in 1., 

 1 in. br., narrowly ovate-lanceolate, hi- or tripinnatifid ; lower pinna; opposite, 

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

 linear-oblong segm. on each side, the largest of which are ^ in. 1., and the lowest 

 again slightly divided ; texture subcoriaceous ; rachis sliglitly fibrillose ; 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 

 Mex. Bound. Survey, vol. 2. p. 234. C. Feei, Moore. 



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

 much less hairy and less divided plant than G. lanuginosa, with larger and less distinctly

 lanceolate-deltoid, about | in. 1., | 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 ; tipper surface quite naked, under surface 

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