NOTES AND ABSTRACTS. 



are partly due to the more abundant nutrition of the former, partly 

 to the direct influence of light (especially in the periderm). In some 

 respects the seedling axis is like the shade form of twig. 



Beech buds developed in sun are larger and have more bud scales 

 than those in the shade. 



The author also discusses the asymmetry of Beech leaves, showing 

 that this is influenced by amount of light. The first leaves of 

 a shoot (not the one at the tip) are the most unsymmetrical.

Lilacs, Leaf Curl. By R. Laubert {Gartenflora, vol. Ixiii. pt. i. 

 pp. 9-1 1 ; I fig.). — Pot-grown lilacs have been attacked with disastrous 

 results by a disease which causes the edges of the leaves to fade and 

 curl over and the leaves to fall in July. This disease is not due to 

 fungi. The diseased leaves are twice as heavy as the healthy leaves 

 and are filled with starch granules. The accumulation of starch is 

 probably due to errors in cultivation, e.g. over-manuring, insufficient 

 watering, or to a check to the development of the roots by using too 

 small pots. 



The leaves of Peaches suffering from leaf curl and gumming are 

 also abnormally rich in starch. — S. E. W. 



Lilies. By E. A. Bowles [Garden, Jan. 4, 1913, p. 11 ; Jan. 11,

Lime-sulphur. By C. P. Scrivener [Agr. Gaz. N.S.W. vol. xxiv. 

 pt. ii. p. 988). — Spraying with lime-sulphur under high pressure is 

 said to be superseding the use of Bordeaux mixture. — S. E. W.
