by Kerr. This was the double white variety; the double yellow was not 

 seen in this country until seventeen years later. This species grows wild 

 in the western mountainous half of China, over a wide range of country, 

 and shows considerable variation. This Rose has long been cultivated 

 in China, and thence introduced into Europe and Japan. B. mAcro- 

 carpa very much resembles the last-mentioned species, but varies in 

 certain particulars. B. Gollctti, found in the Shan States of Burma, very 

 much resembles B. microcarpa, and is apparently a tomentose geographical 

 form of that species. — 67. S. S. 



Sabal Uresana, W. Trelease. By Dr. A. Ragionieri (Bull. B, 

 Soc. Tosc. Ort. vi. p. 177 ; June 1902). — A new Palm discovered by Prof. 

 W. Trelease in August 1000 on the plateau to the north of the city of 

 Ures, the ancient capital of the Mexican State of Sonora. It forms open 

 forests, and is a beautiful and elegant Palm Its glaucous foliage recalls 

 two other beautiful species of the Sonora region, Washing tonia Sonorce, 

 Watson, and Erithea armata, Watson. The stem is 5 to 10 metres high 

 and more than 30 cm. thick ; the leaf -blade is about a metre long, 

 multifid, with large straw-coloured paleas springing from the sinuses. Fruit 

 with a single edible, green, globose carpel, which when dry is dark brown 

 and somewhat polished, and the mesocarp cottony ; the endocarp is of 

 a whitish straw-colour. The seed is shining, of a dark chestnut colour, 

 and labyrinthically rugose, 12x7 millimetres. — W. C. W. 



Sandring-ham, The Gardens at. Anon. (Gaul. Chron. No. 808, 

 p. 403 ; figs. 141 to 151 ; June 21, 1902). — This is an interesting article 

 on the Royal gardens at Sandringham, illustrated with eleven admirable

Scabiosa caucasica, A White-flowered. By S. Mottet (Bev. 

 Hart. p. 347 ; July 16, 1902). — This variety besides being pure 

 white is absolutely hardy, while the normal is scarcely so. It comes 

 true from seed, and is extremely floriferous, blooming freely from mid- 

 June until the October frosts. Highly recommended. — C. T. D. 



Scale, Rose. By J. B. Smith (U.S.A. Exp. Stn., New Jersey, Bull. 

 159 ; 13/6/1902 ; 6 figs..)— The snowy-white scale (Diaspis rosce, Bo ache) 

 which infests Rose trees in the shade is described and figured. The 

 insect has proved a serious pest on Blackberries and Raspberries in New 

 Jersey as well as on Roses. The remedial measures advised are the 

 cutting out and burning of the badly infected shoots ; reasonable 

 thinning of shoots ; the application of whale-oil soap, 1 lb. per gallon of 

 water, in the autumn or early winter ; or a 10 p.c. mechanical mixture of 

 kerosene and water ; another application of a weaker solution of soap in 

 March to kill off the young hatched from the eggs. — F. J. C. 



Scale, San Jose. By W. E. Britton (U.S.A. Agr. Exp. Sin., 

 Conn., Bull. 135, December, 1901 ; 5 plates). — The spread of the insect 

 (Aspidiotus ])emiciosus, Comst.) in Connecticut from August, 1893, 

 onwards is shown, and the regulations enforced in order to check its 

 spread are given. The insect and its life-history are both carefully
