dilFers principally through its more rigid texture, the peculiarly woolly nature 

 of its stalks, and the crowded way in which its somewhat wedge-shaped 

 segments are disposed. — Hooker, Synopsis Filicum, p. 476. 



C. (Eucheilanthes) Cooperae — Eu-cheil-anth'-es ; Coo'-per-a3 (Mrs. 

 Cooper's), Eaton. 



This pretty and delicate-looking, greenhouse species, native of North 

 America, where it is popularly known as " Mrs. Cooper's Lip Fern," gTows, 

 according to Eaton, in clefts of rocks and on mountain- sides near Santa 

 Barbara and near San Bernardino, in California. The plant has a certain 

 affinity with C. vestita of Swartz, a native of Illinois and Cleorgia, but it is 

 distinguished by its bearing glandulous hairs, also by the short rootstock, of an 

 ascending rather than creeping nature, and covered, especially when young, 

 with narrow, crisped scales of a peculiarly dark brown colour. — Eaton, Ferns 

 of North America, i., t. 2. 



C. COriacea — cor-i-a'-ce-a (leathery). Synonymous with C. arabica.

This rare and interesting, greenhouse species, which in Continental gardens 

 is frequently met with under the name of C. rufescens, is a native of Mexico, 

 where it is found at an altitude of 7000ft., from Oaxaca to Cerro de Pinel, 

 Sierra Madre, Sierra San Pedro, Nolasca, and Talca. Its fronds, glabrous 

 (smooth and shiny), of a somewhat leathery texture, and dull green in colour, 

 are tri- or quadripinnate (three or four times divided to the midrib) ; they are 

 wedge-shaped or broadly egg-shaped in form, 1ft, to IJft. long, of which more 

 than half is naked, with leaflets and leafits equally egg-shaped and sharply 

 pointed, while the ultimate segments into which these are divided are all 

 sharply pointed. The stalks on which the fronds are borne are of a glossy 

 red, turning blackish with age. The spore masses are continuous all along 

 the margins of the segments. — Lowe, Ferns British and Exotic, iv., t. 27. 



C. (Eucheilanthes) Dalhousiae — Eu-cheil-anth'-es ; Dal-hou'-si-£e (Lady 

 Dalhousie's), LLooker. 

 This pretty, greenhouse species appears to be closely allied to C. farinosa 

 (of which it may possibly be but a denudate variety with larger and more
