Cryptocoryue continued. 



Stove herbaceous perennials, requiring treatment similar 

 to the tender species of Arum (which see). 



C. ciliata (hair-fringed).* fl. sweet-scented ; spatlie pedunculate, 

 long, tubular, fringed at top. June. I. entire, petiolate, oblong, 

 linear-lanceolate, h. 1ft. East Indies, 1823. 



C. spiralis (spiral), fl. brown. May. h. 1ft. East Indies, 1816. 

 SYN. Arum spirale. (B. M. 2220.) 



CRYPTOGRAMME (from kryptos, hidden, and 

 gramme, writing; in allusion to the concealed sori). 

 Mountain Parsley Fern; Eock-Brake. ORD. Filicea. A 

 monotypic genus of hardy Ferns ; the only species, although

comparatively rare and local, is frequently found in stony 

 situations in the North of England and Wales. Sterile 

 and fertile fronds usually different from the same root; 

 Sori terminal on the veins, at first separate, sub-globose,

afterwards confluent, the con- 

 tinuous involucre formed of the 

 changed margin of the frond, 

 rolled over them till full ma- 

 turity. It is of easy culture 

 in pots or Wardian cases, but 



requires perfect drainage. Allosorut, formerly regularly 

 used for the name of this genus, and even at present 

 regarded as such in some books, is now restricted to a 

 section of the genus Pellcea. See also Perns.

 C. C. acrosticholdes (Acrostichum-like). 



Habit larger and 



stronger than in type ; barren segments thicker in texture, more 

 prominently veined, and not so deeply cut ; fertile ones {in. to iin. 

 long, one line broad ; involucre spreading when mature. North- 

 west America. See Fig. 555. 



C. c. Brunonlana (Brown's). Habit of type, but the fertile 

 segments oblong, about three lines long, one line broad, with the 

 involucre spreading in the mature plant, and a space left free 

 from fruit in the centre. 



CRYPTOMERIA (from kryptos, hidden, and meris, 

 part; referring to the structure of all the parts of the 

 flower being hidden). Japan Cedar. ORD. Cent/era. 

 Evergreen trees. Flowers monoecious ; male catkins soli- 

 tary in the axils of the upper leaves. Leaves rigid, linear- 

 falcate, acute, quadrangular, scattered. Cones less than 

 lin. in diameter, terminal, and solitary; scales loose, 

 cnneate, prickly, with from three to six winged seeds. 

 Cryptomerias are hardy in most parts of this country, but 

 their beauty is only fully developed in deep rich soils, with 

 abundance of moisture, and protection from cutting winds. 

 Propagated by seeds and cuttings, planted in sandy soil, 

 under a handlight. Probably there is only one species 

 (C. japonica) with a fair claim to that title, but several 

 varieties are described as such.
