Tuberoses. By B. D. {Joum. Hort. p. 84 ; Jan. 23, 1902).— These 

 flower only once, and where hothouses are not available they should be

 flower.— a W. D. 



Tulip Bulbs attacked by the Fungus Botrytis parasitica. 



William Carruthers {Jour. R.A.S. vol. lxii. p. 247; 1901). — This fungus 

 forms grey velvety patches, consisting of upright brown branching 

 filaments with heads of whitish spores. " The diseased bulbs should be 

 burned. ... A correspondent in Hertfordshire wrote that he had cured 

 bulbs attacked by a similar fungus by immersing them for some weeks in 

 a powdered mixture of French chalk and copper sulphate called 

 ' sulphosite.' The cure seems to have been as effectual as it was simple."

Vaccinium, Horticultural Status of the Genus, By W. M. 



Munson {U.S.A. Exp. Stn. Maine, Report for 1901, pp. 113-160).— The 

 genus includes about 125 species of wide geographical distribution. 

 North America proper about twenty-five species ; Mexico and Central 

 America as many more. The Himalayan region is particularly rich in 

 species, but, with few exceptions, the genus is unrepresented in the 

 southern hemisphere and in the lower regions of the tropics. 



In America the fruit must have been used extensively by the Indians 

 in colonial times, though there are but few records of such use. Until 

 very recently no attempt has been made at improvement by cultivation. 



The most widely distributed species is V. Myrtillus, and the berries 

 are of considerable importance for food in Germany, Siberia, and with 

 the Indians of the Rocky Mountains. V. uliginosum is the next most 

 widely distributed species, and has large juicy black fruits, which are 

 eatable but not agreeable in flavour as ordinarily found. Of V. Vitix-Id&a 

 the berries are made into preserve, and form an important article of 

 commerce in the seaports bordering the Gulf of Bothnia, whence they 

 are sent to the South of Europe along with Cranberries. The berries of 

 V. ovalifolium are used largely by the natives of the North-West. Of all 

 the American species used for food the most important are, perhaps,
