that in that work the only locality given for this plant is 

 Templeton's station at I,uean. 



There does not seem to be an}' good reason why Poa 

 comp7cssa should in the Cybele be relegated to the Appendix, 

 and stigmatised as an interloper in Ireland. What is there 

 suspicious about it save that, in this country, it is a rare grass, 

 and fails to increase and spread ? These are scarcely sufficient 

 reasons for depriving the plant of its citizenship. It is not a 

 species which is likely to be imported with seed, being 

 scarcely to be reckoned as a fodder plant. That it held its 

 place for so long a period on the walls of Deny is remarkable, 

 seeing that the station is entirely in the heart of the city. It 

 is extremely rare there now, if indeed it be not extinct, but 

 Dr. Dickie, in 1864, said it was rather plentiful on the south 

 wall. 



In Ireland Calliii ielie obtusangula seems to have altogether 

 escaped observation until very recently. It was not mentioned 

 in the first edition of Cybele Iliberniea, being indeed at that 

 time unknown in Great Britain. In the second edition it has 

 several stations in the south and west assigned to it, but none 

 farther north than Westmeath. That it has been overlooked 

 by us, in the north, is certain, as it grows in the City of 

 Belfast. The exact locality is a brackish ditch in Victoria 

 Park, close to the County Down shore of the bay. Mr. G. C. 

 Druce, who is familiar with the plant in England, pointed it 

 out to me one day last August, and I have subsequently found 

 it in a similar brackish ditch at Killough, Co. Down. The 

 northern limit, stated in the Cybele as 51J , must therefore be 

 extended to 54-^'. Now that attention is directed to Callitiiehc 

 obiusangula we may expect to find it still more widely diffused 

 in the maritime counties.
