Valerianella dentata Poll. Clears, Reigate, Surrey, June 30, 1914. 

 This, at first sight, was taken for the variety mixta, but on closer 

 examination the fruits appeared diseased. Mr Kamsbottom kindly 

 examined the specimens and reported that the whole plant was affected 

 by Erysiphe Folygoni DC, a "mildew" that attacks a very large 

 number of species of plants. — C. E. Salmon. 



Valerimiella rimosa Bast. Wheat field, Cromer, v.-c. 27, June 21, 

 1914. — F. Robinson. "I should name this F. dentata Poll., not V. 

 rimosa.'' — C. E. Salmon. " V. dentata'' — G. C. Druce. 



Filago minima Fr. Sand dunes, Ainsdale, S. Lanes, v.-c. 59, 

 July 25, 1914. — J. A. Wheldon. Also from sandy roadside. Fresh- 

 field, S. Lanes, v.-c. 59, July 191 4.— W. G. Travis. " We have been 

 wrong in giving Fries as the authority for this name. Persoon Syn. ii., 

 p. 422, 1807, is the earlier publication, Fries' minima not appearing 

 till 1822. Mr Travis's specimens approach the var. supina Rouy and 

 Camus Fl. Fr. viii., p. 176. Mr Wheldon's are nearer the var. brevi- 

 folia of those authors." — G. C. Druce. 



Gnaphalium luteo-alhum L. Sandy land formerly cultivated, 

 Thompson, v.-c. 28, July 23, 1914. — F. Robinson. "Nice specimens. 

 The label describes them as occurring on ' land formerly cultivated. ' 

 Nicholson [Fl. Norf. 1914, p. 97) calls this species ' doubtfully native ' 

 in the county, but I think that the coast stations (where the plant 

 occurs on apparently virgin soil) need not be regarded with much 

 suspicion." — C. E. Salmon. 



Gnaphalium sylvaticum L. Rough pasture between Shilling Green 

 and Little Hill End, Herts, v.-c. 20, September 9, 1913.— J. E. Little. 



Chrysanthemum 1 [Ref. No. 628]. On cotton-seed refuse, 



Hythe Quay, Colchester, v.-c. 19, June 1914. Near segetum, but 

 flower somewhat deeper yellow and leaves bright green. Plants all small. 

 — G. C. Brown. ^^Chrysanthemum coronarium L." — A. Thellung. 



Artemisia campestris L. Among gorse on dry heath, Barnham 

 Common, v.-c. 28, August 17, 1914.--F. Robinson. "Beautifully 

 prepared specimens. On the Continent this is a variable species, 20 

 varieties being described in the Flore de France." — G. C. Druce. 



Senecio viscosus L. Railway track, Sandsend, Yorks, v.-c. 62, 

 August 13, 1913. — J. E. Little. " Yes. I have found it near Ware." 

 — G. C. Druce. 



Senecio vulgaris lu., forma. [Ref. No. 121]. Stiff clay on dyke, 

 Brean Down, N. Somerset, v.-c. 6, April 26, 1914. — W. C. Barton.
