PoA PALUSTRis L. IN BRITAIN. — Ranging from South Lapland and 

 Finland to North Italy and South Russia, Poa palustris L. is a 

 species which might well be expected to occur in Britain, and 

 possibly, now that it has been detected in one place, may have a 

 wider distribution than is at present supposed. To my friend Mr. 

 William Barclay belongs the credit of discovering it in Perthshire. 

 Mr. Barclay has been lately engaged in investigating the flora of 

 some of the marshes which fringe the River Tay below Perth, and 

 at the end of July found a grass which he did not recognise as a 

 familiar species. On examination we could not make anything of 

 it except Poa palustris, a determination confirmed by Dr. Hackel. 

 P. 2Jalustris bears some resemblance to P. pratensis, P. triviaUs, and 

 P. nemoralis. From P. pratensis the absence of creeping stolons 

 and the long ligule readily distinguishes it; from P. triviaUs the 

 much less conspicuously veined lower pale ; and from P. nemoralis 

 (of which it has been called a variety) the conspicuous ligule. 

 According to Nyman, P. serotina Ehrh., P. fertilis Host., and P. 

 angustifolia Whlnb. are synonyms of P. palustris L. In its Perth- 

 shire locality P. i^alustris grows in association with Carex aquatilis, 

 and is undoubtedly indigenous. The Watsonian vice-county is 

 88, Mid-Perth.— F. Buchanan White.
