Principal Species and Varieties. 



D. carnosum— car-no'-sum (fleshy), Hooker, 



A stove species, native of the Eastern Himalayas, also of Nepaul and 

 Kekeat Island, Japan. Its fronds are produced from a wide-creeping, thread- 

 like rhizome (prostrate stem), which is furnished with fine roots of a fibrillose 

 (hair-like) nature. The barren ones are either elliptical or nearly round, 

 lin. to 2in. long, and lin. broad ; the 

 fertile ones are linear- spathulate (narrowly 

 spoon-shaped), 2in. to Sin. long and 

 ^in. broad ; both kinds are narrowed at 

 the base to a short stalk, and are of a 

 leathery texture. The sori (spore masses) 

 are disposed in a line situated midway 

 between the edge and the midrib, and 

 when young are covered with small 

 scales. Fig. 45 is reduced from Col. 

 Beddome's " Ferns of British India,"

There are two varieties of this 

 species : 



D. C. minor — min'-or (smaller). 

 Hooker. 



This variety, which only differs Drymo^iossum c^mosum 



r. -, (4 nat. size). 



from the species through its smaller 



dimensions, is found in Japan, North China, Fort Hamilton, and Formosa. 



D. C. SUbcordatum — sub-cor-da'-tum (somewhat heart-shaped). Fee. 



In this variety, also native of China and Japan, the barren fronds, smaller 

 than those of the species, are roundish, nearly stalkless, and of a thinner 

 texture. The sori (spore masses) are situated near the midrib. — Hooker,
