Phleum pratense, L., var. stoloniferum, Bab. Donibristle, Fife, 

 v.-c. 89, July 21, 1912.— McT. Cowan, jun. "Yes; but it seems a 

 condition rather than a true variety." — G. C. Druce. " P. p)ratense, L.,

Agrostis verticillata, Vill. Roadsides and quarries, on diorites or 

 syenites, near Yale Castle, Guernsey, Aug. 14, 1912. This plant 

 seems to be confined in Guernsey strictly to the Guernsey ' granite ' 

 (diorites or syenites), and appears only in the quarries or at the sides 

 of roads constructed of ' granite ' or in ditches that drain such 

 roads. — W. C. Barton. " Yes ; it is thoroughly established, if not 

 native, in Guernsey. See Report 1906, p. 199, and Journ. Bot. 1906, 

 p. 320."— G. C. Druce. 



Agrostis verticillata, Yill. St David's, Fife, v.-c. 85, July 10, 

 1911. — McT. Cowan, jun. "No; Agrostis alba, L." — J. Cryer and 

 A. B. Jackson. " Is not this A. alba, L., var. coarctata, Hoffm. ?" — 

 E. S. Marshall. " No ; this is A. alba, var. coarctata, Hackel, as 

 E. Hackel agrees, but the var. coarctata, Hackel, is not the same 

 as coarctata, Hoffm." — G. C. Druce. 



Agrostis alba, L., var. major, Gaud, (v) Cornfield, Walton, S. 

 Lanes., v.-c. 59, July 1912.— J. A. Wheldon. " Yes."— E. Hackel.

Agrostis retrofacta, Willd. Sewage tip near Bradford, v.-c. 64, 

 July 7, 1908. This Australian grass appeared in considerable abun- 

 dance in the season of 1908. In 1909 there was a diminution in 

 quantity. It however has appeared each season since, including this 

 last. Named by Mr A. B. Jackson. — J. Cryer. "Correct." — E. 

 Hackel. " My specimen appears to be a form of Air a caryophyllea, 

 Li., or a nearly allied species ; perhaps there has been an accidental 

 transfer of labels." — E. S. Marshall. " Mr Marshall's specimen was 

 Agrostis retrofacta, Willd. There was no transfer of labels." — J. 

 Cryer. 



Calamagrostis epigeios. Roth, (?) var. densifiora, Ledeb., Fl. Alt. 

 i., p. 87, 1829. I name this provisionally as above, as it agrees with a 

 plant so labelled in Kneucker's Gramineae Exsiccatae, xvii. Lieferung,
