XXXVI ADDENDA. 



p. 194. Under Bryvm erythrocarpum — 



Mr. Wilson considers var. y. murorum, Schimp., which is peculiar to 

 mortared walls, and occurs at Bristol, and not unfrequently in North Wales, as 

 a distinct species, under the name of B. murale, Wils. 



p. 197. Under Bryum pseudotriquetrum, insert — 



Tar. S. cavifolium, Schimp. (Bryum neodamense, Itzigsolm), has been 

 found near Southport by Mr. Wilson. 



p. 198. After Bryum pollens, insert — 



23*. B. Duvalii, Voit; tufted, very soft, bright purple ; stems tall ; leaves 

 distant, spreading, very decurrent, broadly ovato-lanceolate, quite entire ; nerve 

 vanishing below the tip ; sporangium equal, constricted below the mouth when 

 dry. 



In bogs. Found by Mr. Wilson, but I do not know the exact locality. 



p. 254. Under T. oblongifolia, insert — 



Tortula oblongifolia has lately been found in Sussex. I am mistaken in say- 

 ing it is not taken up by Schimper. A description will be found compiled from 

 the ' Bryologia Britannica,' at p. 185 of the Synopsis. It is doubtful whether 

 it really differs from T. Vahliana. 



p. 286. Under Arctoa fulvella, insert — 



(Plate 23, fig. 10.)
