its appearance is totally unlike the more usual state oil 

 H. ciipresuforme ; and we should perhaps have hesitated] 

 about uniting them, had we not seen the one in some cases! 

 running completely into the other. The Hypnum incurA 

 vatum of Schrader and Schvvaegrichen likewise borders! 

 very closely upon this state of H. cuprcssiforme, but it difj 

 fers in the shorter and more cernuous capsule. The varl 

 compresmm is now universally acknowledged to belong tcl 

 our plant ; and we are equally satisfied of Mr. Dickson'J 

 nigro'viride being no other. . I

This most elegant species, so rare in this country, is onl 

 of the most abundant of mosses in the fir forests of Switj 

 zerland, bearing fruit in autumn. It is readily distinguishel 

 from H. molluscum, not only by its much larger size, anl 

 more regularly pectinated stems, but by the strongly stri 

 ated leaves. 



60. H. moliuscum ; stems pectinated ; leaves falcato-secun J 

 cordate, much acuminated, serrated, not striated, faintl 

 two-nerved at the base; capsule oblongo-ovate, curvecl 

 cernuous; lid conical. (TAB. XXVII.)

 Smith supposed. His figures, both A and B, belong trul 

 to our present plant.
