D1CRANEI. 279 



Forming yellowish tufts. Nerve of leaves with pluriseriate 

 teeth ; sporangia more or less cylindrical. The leaf-cells are 

 much more elongated than in the last. 



7. D. majus, Turn. ; tufted, stems incoherent ; leaves very 

 long, falcato-secund, subulate, from a lanceolate base ; fruit- 

 stalks pale, aggregate ; sporangia cernuous or horizontal, sub- 

 arcuate ; beak long. Hook, fy Wils. /. xviii. ; Eng. Bat. t. 

 1409.; (Moug. $ Nest. n. 1014.) 



In woods. Bearing fruit in summer. 



Forming deep-green patches. Leaves in every state falcato- 

 secund, by which character, as well as the aggregate fruitstalks 

 and olive-brown sporangia, it is distinguished from the last ; 

 tips of leaves and nerve toothed as in the last, but the latter 

 has more numerous ridges. 



8. D. palustre, Lapyl. ; tufted, radiculose ; leaves spread- 

 ing, glossy above, somewhat undulated, transversely linear, 

 from a lanceolate base ; toothed above ; nerve slender ; fruit- 

 stalk solitary ; sporangium cernuous, curved, obovate-oblong, 

 turgid ; neck substrumous ; ring none. Hook. Wils. t. xviii. ; 

 Eng. Bot. t. 2260 in part. 



In marshy places in woods, etc. Bearing fruit in autumn. 



Monoicous or synoicous ; forming large yellowish patches. 

 Differs from the last two in the lower basal reticulations, more 

 slender nerve without ridges, subflexuous stem, etc. The 

 leaf-cells are altogether large ; the undulations are at once 

 visible to the naked eye ; upper leaves forming a cuspidate 

 point. 



9. D. Schraderi, Schivceg. ; densely tufted ; stems elon- 

 gated ; leaves crowded, erecto-patent or subsecund, lingulate, 

 lanceolate, rather obtuse, waved, sharply channelled, toothed ; 

 sporangium cernuous, oval oblong ; lid rostrate. Hook, fy 

 mis. t. xxxix. ; (Moug. % Nest. n. 317.)
