508 THE BOTANICAL EXCHANGE CLUB OF THE BRITISH ISLES. 



Phlemn pratense L., var. majus Sinclair. Clover field, Walton, S. 

 Lanes (59), July 10, 1913. When extreme, a very handsome plant 

 in tufts 4 feet high, with broad leaves and long panicles. — J. A. 

 Wheldon. " The forma uberior, vigorous plants, but no distinct 

 variety." — E. Hackel. 



Phleum pratense L., var. nodosum (L.) Aldeburgh, Suffolk, Aug. 

 1913.— G. C. Druce. 



Phleum arenarium L. Formby, S. Lanes, v.-c. 59, May 25, 1913. 

 — W. a. Travis. " Yes."— E. Hackel. 



Agrostis verticillata Vill. Near Yale Castle, Guernsey, Aug. 14, 



1912. See Report 1912, p. 295.— W. C. Barton. " Yea."— E. 

 Hackel. 



Agrostis alba J^. [Ref. No. 9140.] Type. Lenslade, Bucks, July 



1913. As there are so many varieties and forms of this polymorphic 

 species, these are distributed to show what Prof. Hackel considers to 

 be the type. — G. C. Druce. 



Agrostis alba L., var. condensata Hackel. [Ref. Nos. 9802, 9806.] 

 Marsh, Aldeburgh, Suffolk E., July 1913. These exhibit a curious 

 hypertrophy of the glume, which when I first saw it, suggested a 

 Calamagrostis. It was in considerable quantity, but persevering 

 search resulted in detecting some plants with normal florets. Two 

 gatherings are sent, showing that while the varietal character is 

 constant, yet the development of the glume is evidently due to some 

 injury which Prof. Hackel says is probably caused by a Nematod 

 (Tyleuchusl) habiting the ovary and forming a zooecidium — G. C. 

 Druce. 



Agrostis nigra With. [Ref. No. 3819.] In grassy places by the 

 River Lyon, Fortingal, v.-c. 88, Mid Perth, July 15, 1913. Native. 

 Rather young, but it agrees well with Babington's description, and 

 Mr Bennett considers it probably correct. The dark inflorescence, 

 with erect or ascending branches, was very noticeable. — E. S. 

 Marshall. " Yes." — E. Hackel. 



Polypogon littoralis Sm. [Ref. No. 114.] Waste ground, Hythe 

 Quay, Colchester, Essex, v.-c. 19, June 16, 1913.— G. C. Brown. 

 " P. crinitus Ti'in., a very distinct Chilian species not at all resembling 

 P. littoralis.'' — E. Hackel. 



Calamagrostis epigeios Roth. Sowerby Wood, Dalton, v.-c. 69, 

 Aug. 27, 1913. Yery abundant in this locality. It is fairly abundant at 

 Sandscale on a high bank of the Duddon, and on Housethwaite Hill. — 

 D. LuMB. Correct." — Ed. and G. C. Druce.
