7. Isoetes lacustris L. — Tins was marked in a catalogue by 

 Mr. Nicholson with a ?. Mr. Crampton (I. c.) records it from Loch 

 More, Eileneach, Ganeinh, Lochan Dubh-na-Gaoive, Chalinin, 

 Scye, and Shurrey. Occurs in Sutherland (Salmon), Shetland !,

8. Cochlearia GRffiNLANDicA L. — Short turf on Holborn 

 Head, July 14, 1897, E. S. Marshall, sp. This seems to have 

 somehow been omitted in my former papers,* although recorded in 

 the Supplement to Top. Bot. It is a plant that might be expected 

 occurring in Ross!, Sutherland!, the Outer Hebrides!, Orkney! 

 and Shetland !. 



SHORT NOTES. 



Rumex salicifolius in South Lancashire. — A number of 

 plants of this species occurred last year in a clover-field near 

 Walton Prison, Liverpool. It is a North American species which 

 has recently occurred in several localities in Germany and the 

 Netherlands. The name has been confirmed by Dr. Thellung, of 

 Zurich. It is not unlike a slender form of B. crispus in the field, 

 but is of a paler yellowish green, and when in flower its anthers 

 are conspicuously yellow tinted, deepening to orange after anthesis. 

 They are white in B. crispus. The leaves are subcartilaginous, 

 recurved, linear, not crisped, but slightly undulate at the margins, 

 and have a very willow-like appearance. In the same field nume- 

 rous other aliens appeared from time to time last year, and this 

 including Papaver Bhceas L., Sisymbrium pannonicum Jacq., S. 

 orientate L., Silene dichotoma Ehrh., Melilotus officinalis Lam., 

 M. alba Desv., M. Petitpierreana Hayne, M. indica All., Trifolium 

 pratense var. americana Harz, Oenothera Lamarchiana Ser., 

 Daucus Carota L., Artemisia Absinthium L., Potentilla norvegica 

 L., Chenopodium opulifolium Schrad., Rumex dentatus L., and 

 Cynosurus echinatus L. I have seen no previous British record 

 for Rumex salicifolius. — J. A. Wheldon. 



FESTUCA ROTTBffiLLIOIDES Kunth IN SOUTH LANCASHIRE. — In 



preparing the Flora of South Lancashire it has been necessary to 

 visit all kinds of localities, whether botanically interesting or 

 uninteresting. The portion of the Mersey shore near Garston 

 belongs decidedly to the latter category. Mr. W. G. Travis, the 

 Secretary of the South Lancashire Flora Committee, decided to 

 pay a long postponed visit to this part of our area on July 19th, 

 and was rewarded by the discovery of this grass on the river-wall 

 at Garston Docks. It occurs in considerable quantity, and there 

 is no reason to doubt that it may have been an original plant of 

 the rocky shores hereabout prior to the building of these walls. 

 Its only associates were native plants, such as Plantago coronopus, 

 Alsine media, Sagina maritima var. prostrata Towns., &c. There
