REPORT FOR 1914.

Senecio lautus Forst. Bank^^ of Tweed, Selkirk, v.-c. 79, Septem- 

 ber 1914. Native of Australia. Growing in this neighbourhood it 

 does not increase by its own fruits, but by rooting all along its old 

 wood. On a plant of two years' growth I counted 70 old stems, and 

 the branches shooting from them each bearing on an average 190 

 blossoms. — I. M. Hayward. 



Cirsium lanceolatum Scop, x acaule Weber. Undercliff, Milford-on- 

 Sea, S. Hants, v.-c. 11, August 1914. I send a few more sheets of 

 this plant to supplement those sent last year. A further examination 

 in situ convinces me that whatever it may prove to be, it is certainly 

 not the typical caulescent state of C. acaule. The phyllaries have 

 patent or sub-patent spinous tips, whereas those of C. acaule are 

 mucronate only. The leaf segments are longer, narrower in proportion 

 to their length, and more parallel sided ; and the petioles, especially 

 of the lower leaves, more spinous-ciliate. The whole facies of the 

 plant is different — greyer in colour, and considerably rougher and 

 coarser looking. It also flowers at least a week or ten days earlier. — 

 J. Comber. "See Report 1913, p. 476. I can add nothing to my 

 remarks, except to say that one is better qualified to judge after seeing 

 the plant growing with its supposed parents. Dr Thellung says : 

 scarcely x lanceolatum." — G. C. Druce. 



Cnicus oleraceus L. Marshy meadow at Limehaugh, E. Perth, 

 August 11, 1914. This thistle appeared first in 1911 in a marshy 

 meadow close by the River Tay, which in very high floods is liable 

 to be inundated. It has appeared every summer since to the number 

 of 60 or 70 flowering heads. As the meadow is cut about the end of 

 August, it is doubtful if the plant produces ripe seed so as to give it 

 the chance of becoming thoroughly naturalised. Although not a 

 native of Britain it is common in Central Europe and in Scandinavia. 

 — W. Barclay. "Being found in South Scandinavia, Denmark, 

 Holland, Belgium, France, and Germany, it should occur as a native 

 in Britain." — E. S. Marshall. " Yes, Cirsium oleraceum Scop. 

 Also naturalised near Selkirk (Hayward)." — G. C. Druce. 



Centaur ea Jacea L., var. pratensis Koch. Ditcham Park, Hants, 

 August 25, 1914. A rather short small-flowered plant easily dis- 

 tinguished from the C. decipens and C. nigra forms growing with it. 

 Heads sometimes rayed. — B. S. Adamson. Referred by Dr Thellung 

 to C. nigra L. (pappus distinctus), sub.-sp. eunigra Gugler. Folia 

 insuete angusta. 



1 Centaur ea nigra L., var. Hough pasture on clay, Ditcham Park, 

 Hants, August 25, 1914. A very distinct small-headed form which 

 seems near C. Deheauxii Gren. k Godr. — R. S. Adamson. " According 

 to the somewhat artificial key of H. Saintange Savourie, this seems to
