 be converted into the acid. — V. G. J. 



Lenticels, Exuberant Formation of, in Oak Seedling*. By 



Bertha Chandler (Trans. Roy. Bot. Soc. Edin. vol. xxiv. part. i. pp. 35 

 and 36; 1 plate). — The presence of an excessive water supply to 

 seedling oaks caused the abnormal lenticel formation figured.

Lig-ht and Heat, Influence of, in the Production of Org-anic 

 Matter in Tea Plants. By J. Bosscha (Ann. Jard. Bot. Suit. 

 viii. series ii. pp. 66-68). — A relation exists between the clearness of the 

 sky and the amount of growth of the leaves of the tea shrubs. The 

 clearness of the sky was judged by the daily difference between tlje 

 minimum and maximum temperature. This is termed the amplitude 

 of temperature. — S. E. W. 



Lilies. By E. H. Jenkins (Garden, Sept. 4, 1909, p. 429).-- 

 L. candidum is a sun lover, and shallow planting should be practised. 

 It may be planted near trees with excellent results, especially near 

 yew, holly, or pine, which show up the purity of the blossoms. The 

 drier conditions frequently found in such places are a material help in 

 keeping the lily disease in check. Some bulbs weakened by disease 

 were planted at the foot of a laburnum and allowed to become covered 

 with London pride; they had given moderately good spikes each year. 



L. testaceum possesses some affinities with L. candidum.. 

 L. Hansoni should be planted where there is shelter from cold winds 

 and strong sunlight ; it is the better if the root run is in comparative 

 dryness. It and the forms of L. auratum are at home in the root 

 companionship of other plants; they are particularly benefited from 

 association with rhododendrons. Lilies without stem-roots — e.g. 

 L. ckalcedonicum and the swamp lilies — are usually slow to become 

 established. 



L. Henryi should be staked and tied low down, and afterwards 

 allowed to go its own way. — H. R. D. 



Lilium candidum. Disease in. By Mrs. L. M. (Garden, Sept. 18, 

 1909, p. 455). — A bad attack was cured by digging up the bulbs, burn- 

 ing the worst, and keeping the rest in a bag of sulphur for six weeks 

 before replanting. — H. R. D. 



Lilium nepalense. By A. M. (Garden, Oct. 9, 1909, p. 491).— 

 At Ambleside this lily does well if taken up directly it has flowered, 

 put into a box (not pot), and wintered in a cold frame. — H. R. D. 



Lime and Sulphur. By P. J. Oarmody (Jour. Dep. Agr. Vict., 

 September 1909, p. 586).— Lime, 20 lb.; flowers of sulphur, 15 lb.; 

 water, 50 gallons. Slake the lime in about 20 gallons of water, and 

 add the sulphur, previously mixed up into a stiff paste, to the slaking 

 lime. The whole mixture should be boiled for one hour in an iron
