leaflets disposed in opposite pairs, tlie lowest the largest, oblong or again 

 branched on the lower side. The small and copious sori (spore masses) are 

 disposed all round the segments, which are roundish- oblong and deeply 

 notched. — Hooker^ Synopsis Filicum, p. 136. 



C. (Adiantopsis) incisa — Ad-i-ant-op'-sis ; in-ci'-sa (cut), Kunze. 



A very distinct, greenhouse species, native of South Brazil, with fronds 

 seldom more than 4in. long, including their slender, naked, polished, dark 

 brown stalks. The lower leaflets, of a somewhat leathery texture and about 

 lin. long, are cut down to the midrib into several oblong pinnules (leafits) 

 with narrow, sharp-pointed segments, on the margin of which the sori (spore 

 masses), few in number and roundish or transversely oblong, are situated. — 

 Hooker, SynojJsis Filicum, p. 133. 



C. (Adiantopsis) Kirkii — Ad-i-ant-op'-sis ; Kirk'-i-i (Kirk's), Hooher. 



A stove species, of singular appearance, native of the Moramballa 

 Mountains, Zambesi Land, where, according to Dr. Kirk, it grows on rocks 

 at elevations varying between 200ft. and 500ft. It is a curious plant, with 

 fronds deltoid (in the shape of the Greek delta. A), 4in. to 6in. each way, borne 

 on densely-tufted, erect, naked stalks Gin. to 9in. long, of a chestnut-brown 

 colour, and it has entirely the habit and other characters of the popular 

 Pellwa (Fteris) geranicefoUa, from which it is distinguished only by its mode 

 of fructification, the small and roundish sori (spore masses) being disposed all 

 round the margin of the segments, where they are not confluent. — Hooker, 

 Second Ce?itury of Ferns, t. 81. 



C. (Eucheilanthes) Kuhnii — Eu-cheil-anth'-es ; Kuhn'-i-i (Kuhn's), 

 Milde. 



A greenhouse species, native of China, and very similar to C. suhvillosa, 

 from which it differs only through its being of smaller dimensions and through 

 its fronds being covered with a glandular j)ubescence (down). — Hooker, Synopsis 

 Filicum, p. 476. 



C. lanosa — la-no'-sa (woolly). The plant known by this name is identical 

 with C. lanuginosa.
