near Mickle TrafFord Station, Cheshire, v.-c. 58, July 16, 1912.— C. 

 Waterfall. " Bad specimens of F. heterophyllum, Lindm.!' — G. C. 

 Druce. 



Polygonum Roherti, Lois. Duddon Estuary, Askham, v.-c. 69, 

 Sep. 13, 1912. I can't understand why the books say that the leaves 

 of this plant are flat. In Bah. Manual the word is in italics. Mr 

 Hodson, Flora of Cumberland., says that the plant which called into 

 existence the trivial Rail., was gathered on a part of the Cumberland 

 coast not far from here. — D. Lumb. " Yes, a new county record 

 for 69."— G. C. Druce. " Is not this F. Rail, Bab., rather than F. 

 Roherti, Loisel.1 The latter is a small-fruited (2 to 3 mm. long) plant 

 with a distribution distinctly south European. Mr Lumb's plant 

 possesses large (4x3 mm.) exserted fruit. In descriptions of F. 

 Rail, it is usually stated that the leaves are flat, but my experience 

 leads me to believe that the margins of the leaves may frequently be 

 recurved, as in F. litorale, Link, and Mr Lumb's plant shows these 

 recurved margins." — C. E. Britton. "P. Raii, Bab. Loiseleur's 

 species is a plant of southern Europe." — E. S. Marshall. 



Rumex crispus, L., var. trigranidatus, Syme. ' Slacks ' in the 

 sand dunes, Birkdale, S. Lanes., v.-c. 59, July 7, 1912."— J. A. 

 Wheldon. ''^Ya^ ; trigranidatus \^ ?i>Q,ommon littoral form." — G. C. 

 Druce and E. S. Marshall. 



Rumex crisjms x sanguineus, var. viridis ( R. crispus x nemorosus ). 

 [Ref. No. 779.] Lower Morden, Surrey, July 24, 1912.— C. E. Britton. 

 " Looks right ; but gathered a fortnight too early to show the fruiting 

 character." — E. S. Marshall. "Yes; apparently the x R. Sagorskii, 

 Haussknecht." — G. C. Druce. 



Rumex rup>estris, Le Gall. Origin, Whitesaiid Bay, Cornwall, 

 cult., at Clifton, July 1912.— J. W. White. 



Rumex Acetosella, L., forma stolonifera. The normal form is 

 abundant on a stretch of sandy railway bank about seven miles from 

 Rugby. In places the surface soil seems composed of engine cinders, 

 and on these patches alone the plant becomes stoloniferous, plants 

 growing on sandy soil a foot away being quite normal. — L. Cumming. 

 " The rhizomatous character of this species has been alluded to 

 {Journ. Bot., 1892, p. 262) by the Rev. E. F. Linton. As my specimen 

 is only the male plant, I am unable to say to which variety it belongs." 

 — G. C. Druce. " The species is normally stoloniferous, as those whose 

 gardens it invades have too good cause to know." — E. S. Marshall 

 and J. A. Wheldon,
