very strongly wavy. Drummond's Dicranum grows on rotten 

 wood ; its leaves are somewhat secund and are very strongly 

 crisped when dry, also very slightly wavy; they are much more 

 slender pointed than in the Wavy Dicranum. The capsules of 

 the two species are very much alike. 



The Flagellate and Fulvous Dicranums need never be con- 

 fused, for the former grows on rotten wood or peaty banks, while 

 the latter always grows on rocks. The Flagellate Dicranum has 

 slender branchlets (flagella), with minute leaves, which give it 

 its name. The Fulvous Dicranum lacks these flagella and is 

 usually somewhat brownish-fulvous in color. Its leaves are much 

 longer, with a very broad thick midrib. The differences in the 

 leaves are best seen by mounting them as for the compound 

 microscope. 



DICRANELLA 



THE Common Dicranella [D. heteromdlla (L.) Schimp. J looks 

 like a little Dicranum, as its name would imply. It is fre- 

 quent on moist shady banks in regions somewhat removed 

 from the coast. Near the coast, particularly in the southern por- 

 tion of our range, 

 •c-^f^ the variety with 



straight capsules 

 (var. ort/iocarpa 

 Hedw. ) is common 

 i n rathe r dry 

 sandy soil. The 

 species is rather 

 taller with the 

 capsules some- 

 what longer and 

 more oblique, and 

 slightly f urr o w ed 

 when dry. Both 

 forms mature 

 the capsules in 

 autumn.
