48 ON TWO ADDITIONS TO THE BRITISH MOSS-LIST. 



coloured cells somewhat larger than the rest, while the basal cells 

 are uniform. In F. polypkyllua the leaves taper gradually to a 

 point ; they are destitute of a border ; entire, except at the 

 serrulate apex ; and the cells of the base are gradually enlarged 

 from the margin inwards towards the nerve, those of the long- 

 decurrent angles being linear-oblong. Another difference between

 8 or 9 leaved in pohjpliyUus. 



As far as our islands are concerned it can scarcely be hoped 

 that this interesting species will be found, except on the western 

 or south-western coasts ; Cornwall, the South of Ireland, perhaps 

 the Hebrides. It belongs to a group representing a more southern 

 flora, whose presence here is probably due to the influx of the 

 Gulf- stream; Daltonia splachrwides, Hooheria Icete-virens, Myurium 

 Hebriflarum, &c. Visitors to Killarney should bear it in mind: 

 F. polyphtjllus is plentiful thereabouts, and the other may occur 

 too, as both grow in Cornwall very near each other, and yet, 

 though the locality has been much investigated, this by no means 

 small moss has been hitherto overlooked, and by some of the 

 keenest and most practised eyes.

excellent friend, Dr. Wood, who had communicated the discovery 

 to him : — 



"The discovery of Fissidens serrulatus in England is a most 



interesting circumstance, and one proof the more that the British 



Isles possess a great many species in common with the South of 



Europe, and especially with Spain, Portugal, and the Canary 

 Islands. 



" In fact, England with its adjoining islands is a veritahle 

 Mdorado of mosses, participating as it does in the bryological 

 flora of the North, of the South, and of the Intermediate Zone, 

 and there are doubtless other discoveries to be yet made." 

 t All botanists will regret to hear that, since gathering this 

 interesting moss, Mr. Curnow has had the misfortune to fall and 

 break a leg, but appears to be doing well, and it may be hoped 

 that this is not his last discovery.

of Dr. Spruce should be doubted in the matter of a moss so easy
