named by Mr. Arthnr BennQit A g ropy ron repens, var. aristatumy 

 Doell. On the coast inside the islands called Launches, 

 Jimais obtjcsiflorus grew, with QL7ia7ithe Lachenalii and 

 Lep tunes ; and from the train in the evening Spargaiiium 

 miniviu7}i was seen in pools at Ballynahinch Junction. But 

 during the three days my eye was so constantly glued to the 

 strip of vegetation along high watermark, that my notebook 

 was almost a blank as regards plants from any other habitat. 

 The result of this exploration, and of that of last year, is to 



show that the headquarters 

 of Glyceria festuccs/ormis 

 lie in the Quoile estuary, 

 in the south-west corner of 

 Strangford Lough. Thence 

 the plant extends north- 

 ward for some miles, in 

 fair quantity on the eastern 

 side of the lough, apparently 

 very sparingly on the 

 western. In the northern 

 half of the lough, embrac- 

 ing the districts of Ard- 

 millan, Comber, Newtown- 

 ards, and Greyabbey, it is, 

 so far, an absentee. There 

 is, in addition, the out- 

 lying station on the Irish 

 Sea coast near Cloghey 

 Bay, which suggests a much 

 wider range of distribution. 

 It appears that an examina-

tion of such of the numerous islands in the lough as are too 

 small to be grazed, would be likely to yield good results, but 

 this interesting piece of work must wait for another season. 



I .have to thank Dr. Rendle for kindly examining some 

 doubtful specimens. While normal G festucceformis looks 

 utterly different from normal G^ maritima, the group Atropis 

 is, as Prof Hackel wrote when first naming the Irish plant, a 

 critical one, and I found it difficult in the field to say where 

 strong G, maritima stopped and weak G. festuoE/ormis h^ga-n.
