THE Bryum truncatulum is one of the leaf! of our Mofies, and diftinguifhable at firft fight by the great number 

 of its little brown heads, which, when the operculum falls off, have their margin entire, fo that they appear as 

 if cut acrofs, whence its name of truncatulum. 



It is very common almoft every whereon banks, producing its fructifications from September to February. 



It varies much in fize. 



Hasselquist, in his journey to Pale/line, finding the Walls of Jerufalem covered with this little plant, calls it 

 Hyffopus Solomonls, from a fuppoiition that it was the plant which Solomon meant, when he fpake of trees from the 

 Cedar in Lebanon to the Hyflbp which fpringeth out of the wall.

THIS fpecies differs from the above in many particulars. It grows in clofe foft tufts, which are in general 

 larger, and of a more yellow hue ; the ft alks are frequently branched ; the leaves are much finer, being nearly 

 capillary; the mouth of the capfule, when the operculum falls off, is narrower than the middle, hence it bears a 

 greater refemblance to an egg, with the extremity cut off; while the truncatulum approaches more to the form of 

 an urn. In the viridulum, the mouth is alfo very finely ciliated. 



The viridulum grows in great abundance on the banks furrounding Charlton Wood; and produces its fructi- 

 fications with the truncatulum.
