pinnules, of the same shape and scarcely |m. long, are deeply pinnatifid, being 

 cleft into oblong, blunt, entire lobes. Each lobe bears a solitary sorus (spore 

 mass), covered by a roundish involucre that eventually breaks irregularly 

 into three or four portions. — Hooker., Second Century of Ferns, t. 99.

C. Milnei— Mil'-ne-i (Milne's), Hooher. 



A strong-growing, greenhouse species, native of Sunday or Raoul Island 

 (of the New Zealand region), having the general aspect of C. affirms, but 

 making a smooth trunk 30ft. in height and 9in. in diameter. Its fronds, of 

 a somewhat leathery texture, are blackish-green above, and paler, though not 

 glaucous (bluish-green), beneath. The leaflets, I|ft. to 2ft. long and 6in. to 

 lOin. broad, are divided into elongated -oblong pinnules (leafits) that are deeply 

 pinnatifid, forming oblong-sickle-shaped lobes, with the margins toothed and 

 shghtly recurved. The abundant sori (spore masses) are moderately large 

 and mostly situated at the base of the lobes near the vein ; they are covered 

 by rather firm, long- persistent involucres of a cup-like form, with very 

 irregular margins occupying most of the breadth of the lobes. — Hooher, 

 Synopsis Filicum, p. 26. 



C. Moorei — Moor'-e-i (Moore's), Baker. 



A greenhouse species, native of Lord Howe's Island, having a general 

 habit very like that of Alsophila australis, but distinct through its fronds 

 being regularly tripinnate (three times divided to the midrib), and also through 

 its small sori (spore masses) being medial and covered by depressed, fragile 

 involucres, breaking up irregularly and sometimes quite disappearing. — Hooker, 

 Synopsis Filicum, p. 453. 



C. patens — pat'-ens (spreading), Karsten. 



A greenhouse species, native of the Andes of Bogota, and much resembhng 

 C. frondosa (from the same habitat) : it differs principally through its larger 

 sori (spore masses) and its pinnules (leafits), which have short but 

 conspicuous stalks. — Hooker, Syiiopsis Filicum, p. 451. 



C. petiolata — pet-i-ol-a'-ta (petiolate, stalked). Synonymous with C. integra.
