Diplnjscium.'] APLOPERISTOMI. 31 



Totness; near Chelwill in the same parish; also, near 

 Meavy Parsonage; always growing upon the hollow 

 mouldering parts of high hedge banks. 



The stems grow in a loosely tufted manner, and are scarcely 

 half an inch in height, and in all the specimens that we have 

 seen, simple, on the lower half bare of foliage, the upper bear- 

 ing leaves of a lanceolate figure, nerveless, much reticulated, 

 and springing from two opposite sides of the stem in a pinnated 

 manner. These are decurrent at the base, but, by no means 

 confluent, the upper and lower ones the smallest, so that the 

 outline of the frond is lanceolate. The fructification is terminal, 

 the fruitstalk about equal in length to the stem. The Capsule 

 spherical, and, as well as the operctdum, pale brown. 



Whilst this very sheet was in the press, we have received, 

 from an unknown friend, the Nottingham Journal for April 1, 

 1826, in which we find the following station given for this 

 exceedingly rare moss. "The Schistostega pennata is now 

 abundantly in fructification in Nottingham Forest, where it 

 grows on the roofs of the sandstone caverns, just beyond the 

 Jews burying ground, on the west side of the Gallows Hill." 

 This notice is contained in a very interesting memoir, entitled 

 the Botanical Calendar for Nottinghamshire, which bears the 

 signature of II. Rosajo.

We are quite unable to detect any thing like a second peristome 

 in this genus, and therefore not unwillingly follow Weber and
