JOURNAL OF THE ROYAL HORTICULTURAL SOCIELY. 



to grow V. speoiosa out of doors the whole year round, and, of the forty or 

 fifty species in cultivation, very few can be said to be sufficiently hardy to 

 stand unharmed through a winter of moderate severity. V. Traversii 

 stands the best, though in a very severe winter it is damaged ; but when a 

 succession of mild winters is experienced it becomes strong and sturdy, 

 and grows into a bush 2 1 feet or 3 feet high, and 3 feet to 4 feet through. 

 Like the other shrubby species, it is from New Zealand. 



The leaves are small and deep green, the flowers white with purplish 

 anthers, and borne in short, stiff racemes in summer. — E. T. C. 



Viola calcarea. By Mrs. E. S. Gregory (Journ. Bot. 495, pp. 67-68 

 and pi. 457 ; 3/1904 ; and 498, pp. 186-7, 6/1904).— A claim for specific 

 rank for the Violet from chalk and limestone hills in Somerset, Cam- 

 bridgeshire, Bedfordshire, Kent, Surrey, and Dorset, previously considered 

 a state, form, or variety of V. hirta. Its distinctive characters are a woody 

 rootstock with thick branches, peduncles much longer than the leaves, 

 narrow petals, and a very short, almost imperceptible, straight, conical 

 spur. — G. S. B. 



Violets, Floral Variations among. By C. E. Britton [Journ. 

 Bot. 497, pp. 140-148 ; 5/1904).— A careful study of the flowers of 1,000 

 specimens of each of the five species, Viola odvrata, V. hirta, V. sylvestris, 

 V. Riviniana, and V. ericctonim, as growing w T ild in Surrey. — G. S. B. 



Vine Borders, in and out. By S. Castle (Fr. Fl. d- Veg. Trades 

 Jour. No. 8, p. 114). — It is contended that the wet summer of 1903 

 reveals the fact that outside borders for Vines have produced crops of 

 both ' Alicante ' and 1 Gros Colman ' Grapes of a far heavier character 

 than is usual, and this is put down by the growers as due to the extra 

 rain supply to the roots of such borders. It is true that successful crops 

 have been obtained from inside borders, to which very free w T aterings were 

 applied ; but one leading grower, who has both inside and outside borders, 

 says that the result cannot be put into comparison with the rain-watered 

 borders. That the outside border in a dry season does suffer, even under 

 good culture, is very often the case ; but no amount of water put on by 

 the cultivator can ever equal the rain-water supply ; the natural con- 

 stituents of the latter give it a value over that from the usual pipe 

 supply. — B. D. 



Vine Diseases, Simple Cure of. By Ed. Andre (Rev. Hort., Feb. 16, 

 1904, pp. 83-84). — Oidium completely eradicated by syringing with very 

 hot water from 70° to 80° Cent., which Vine leaves bear w T ith impunity, 

 though adjacent Rhubarb leaves were parboiled. Woolly aphis yielded 

 to syringing with concentrated infusions of Walnut leaves. A trial was 

 made, with complete success, of brushing infected places hard with stiff 

 bunches of green Walnut leaver; rubbed vigorously in. The pest entirely 

 disappeared. — C. T. J).
