nerve reaching more than halfway up ; fruitstalk even ; spo- 

 rangium elliptic, oblong, somewhat cernuous, rarely erect or 

 symmetrical ; lid rostrate, about half as long. 

 . This species is placed by Wilson and others in Isothecium, 

 but the sporangium is by no means constantly symmetrical, 

 and the inner peristome has intermediate teeth, as in true 

 Hypna. I think, therefore, that Schimper is quite justified 

 in placing it in Eurhynchium. He says that it prefers sandy and 

 granite formations ; but it certainly is by no means confined 

 to them in England. Its close resemblance to Isothecium 

 myurum has mainly contributed to its being placed in the 

 same genus. 



21. H. strigosum, Hoffm. ; stem creeping or decumbent, 

 subpinnate ; branches suberect, attenuated ; leaves crowded, 

 imbricated, spreading, widely cordato-ovate, concave, rather

On the roots of trees, banks, and dry rocks. Said to have

 flat, or swollen, dense tufts ; stem creeping ; branches pin- 

 nate, erect, or prostrate, attenuated or flagelliform ; leaves 

 broad at the base, acute but scarcely acuminate, sharply 

 serrated ; paraphylla numerous, roundish, or ovate ; fruit- 

 stalk even ; sporangium cernuous, subhorizontal. 



22. H. circinatum, Brid. ; stem suberect, arcuate, sub- 

 pinnate ; branches subfasciculate, curved and drooping ; leaves 

 narrowly ovato-acuminate, crowded, subsecund; nerve reaching 

 almost to the tip ; fruitstalk even ; sporangium ovate, cernuous, 

 curved; lid rostrate. Hook, ty Wils. t. Iv.
