Trifolium arvense, Campanula Trachelium, Galeopsts Tetrahit var. lijida, 

 and G. Ladanum, Polygonum mamdatum, Bromus arvensis, secalinus, 

 and an undetermined species, and Alopecunis agrestis are not in the

London Botany. — Senecio viscosus, L,, has now come up in fair 

 quantity on the gravelly margin of the west side of the Metropolitan 

 Railway Station at High Street, Kensington ; it also occurs on the 

 east side of the rail at the wall base just going out of the station to 

 the south, near where the engines take coal in. Rumex pulcher 

 is thickly spread, just now, over Palace Green, Kensington. A tuft 

 of Sinapis tenuifolia is in flower on the Kensington vicarage wall in 

 Church Street ; Equisetum arvense may be found under a wooden 

 wall in Victoria Road. I have found two plants of Lepidium ruderale 

 in Kensington, just west of the Palace. — J. L. Waeeen. 



Vallisneeia spiralis. — Can any of your readers connrm my 

 observation of the extraordinarily rapid growth of the flower-stalk of 

 this plant ? It was first observed in my aquarium about 10 a m. on 

 July 19th, and measured 26 inches, this being almost certainly the 

 growth of the previous 48 hours. At 10 a.m. on July 20th, it 

 measured 38 inches, or had grown 12 inches in 24 hours. At 4 p.m. 

 on the same day the length was 41 inches; 10 a.m. the next morning 

 42;^ ; and 10 a.m. on the 22nd, 43 inches, its ultimate length. Prom 

 the time when first observed — the 19th — till the 31st, when I left 

 home, the flower, a female one, remained open without any apparent 

 change, not being fertilised during that time, as no male flower made 

 its appearance. There was no coiling or uncoiling of the flower-stalk 

 during the whole time; only a slight waviness. — Alfeed W. 

 Bennett. 



Pyeola minob, X., IN LiNCOLNSHiEE. — I havo the pleasure of 

 recording another county for this beautiful little plant. My friend, 

 Dr. R. M. Bowstead, sent me fresh specimens in June last from 

 Osgodby Lane, near Caistor, Lincolnshire, and others from Ussleby 

 "Wood, about three miles from Market Rasen in the same county. I^o 

 Pyrolais recorded from Lincolnshire in '^ Topographical Botany;" 

 but P. rotundifolia IS given as occurring near Gainsborough in **A 

 short Guide to the County of Lincoln," by Charles Anderson (1847), 

 although in the absence of additional evidence, this record must be 

 considered as at least doubtful. Mr. Roper states (p. 213) that P. 

 minor is " essentially a northern plant," a statement which seems 

 to me to require some qualification, although the plant is no doubt 

 far more abundant in the North than in South Britain. In the south 

 of Buckinghamshire it is of very frequent occurrence, extending over 

 a large district, of which Burnham Beeches, Beaconsfield, Chesham, 

 Aston Clinton, Wendover, Missenden, Bradenham, Turville, Paw- 

 ley, Parmoor, Marlow Common, and Loudwater may be taken as the 

 outside limits. About High Wycombe there is scarcely a wood of
