Note on Rhynchostegium litoreum Bott. 



Among a small collection of mossos made for me in 1903 by 

 my siller, Miss H. W. Dixon, in Iho neighbourhood of Algiers, 

 there occurred one from the Frais Vallon which at first sight had 

 the appearance of Eurhynchium (or Bhijnchoslegium) tcnrlhim 

 (Dicks.) B. S. A closer examination however showed that tlie 

 leaves were a little more rigid, with a tendency to a complanate 

 arrangement, less finely tapering, and with a shorter nerve, and, 

 especially, the seta was scabrous. The leaf characters were indeed 

 slight, and in this respect it hardly differs from a specimen oi /I. 

 tenellum var. meridionale from Tunis, leg. Theriot, except fur the 

 slightly broader leaves with rather shorter, less tapering points, and 



a rather stronger tendency todonticulalion at the apex. These cha- 

 racters however together wmUi the scabrous seta showed that it 

 belonged to Itlninchostegium liloreum Bott. (Ffypmim litoreum De 

 Not.). This determination was kindly confirmed by D^ Marchese 

 Botlini, who also informed me that it had not hitherto boon recor- 

 ded from Algeria, and it is so far as I am avNare its first occurrence 

 from the southern shores of the Mediterranean. In Europe the 

 distribution of II. liloreum as at present known is fairly wide- 

 spread along the Mediterranean coast, while it occurs also in two 

 or three localities in the South of England, chiefly along the 

 English ChanncL
