Senecio vulgaris, L., var. , Larne, Antrim, July 1912. Not 



recorded in Cyhele Hibernica for North Ireland. Prof. Trow thinks 

 this may be a praecox hybrid although the foliage is not suggestive of 

 that parentage. — G. C. Druce. 



Senecio vulgaris, L., x >S'. vulgaris, L., var. radiatus, Koch. 

 Growing in a garden at Llandaff, 1912. Very probably this hybrid. 

 — H. J. Riddelsdell. 



S. vulgaris, L., var. radiatus, Koch (though not as described in 

 Bab. Man., for the rays are broad and patent and many, each as long 

 as the disc is broad). Garden, Llandaff, v.-c. 41, Nov. 29, 1912. — 

 H. J. Riddelsdell. 



Senecio vulgaris, L., var. rubricaulis, Trow. Burstow Park, near 

 Outwood, Surrey, May 1, 1912. This pretty Groundsel attracted 

 attention by its red stems, woolliness, and stiff crisped leaves. It is 

 evidently closely allied to the Cross Common Groundsel, mentioned 

 by Dr Trow in the Journal of Genetics, ii., p. 271, 1912. The name 

 on the label is suggested by Dr Trow. — C. E. Salmon. "Trow wrote 

 S. rubricaulis.'' — G. C. Druce. 



Senecio erectus, Trow. Sandy fields, Mildenhall, Suffolk, v.-c. 26, 

 April 20, 1912. A very common weed on cultivated and waste land 

 on all calcareous soils in the Cambridge district. — R. S. Adamson. 



Senecio spathulifolius, DC. This grew in marshy places among 

 the sand dunes of Le Touquet, France, and I thought members might 

 like to have it to compare with their Holyhead specimens. In the 

 vicinity I saw seedlings of Acer as anthropophora growing among the 

 pine-needles in the wood. — G. C. Druce. 



Echinops Ritro, L. Of this European species a few specimens were 

 seen naturalised by the stream in the Forge Valley, N.E. Yorks., 

 Aug. 1912. In the vicinity was Anchusa sempervirens. It is an 

 addition to our list of alien species. — G. C. Druce. 



Arctium nemorosum, Lej. {intermedium, Reichb. fil.) North slopes 

 of Craig Breidden, Montgomeryshire, N. Wales, at 250 feet upwards, 

 Aug. 5, 1912. — J. C. Melvill. "Is Lappa minor, DC. = Arctium 

 minus, Schrank." — J. A. Wheldon. " Surely, A. minus, Bernh. 

 Dr Moss informs me that the name of nemorosum, Lej. cannot stand." 

 — E. S. Marshall. Arctium pubens,^aih. iovmsi glabresce7is.'' — A. 

 Thellung. " I should call this minus ; it has not the habit, size of 

 heads, etc., of nemorosum, Lej., of which I have a photograph of 

 type." — C. E. Salmon.
