He first describes the physiology of assimilation, &c., which requires certain 

 rays, and the injurious effect by their reduction within a room ; the nature 

 of chlorophyll and its functions, especially in the formation of starch, and 

 the hindrances to its production. He gives (in the March number) a 

 diagram showing the relative amount of light received at different dis-_ 

 tances from a, window, viz. from the window itself to 1 and 2 metres. 

 The quantity varies from '5 of the whole amount of light, as in the open 

 air, to 0'079 at a distance of 2 metres. — G. H. 



Lilacs, Persian, and Crosses. By L. Henri {Be v. Ilort. pp. 39, 

 69, and 98 ; figs. 8, 9, 10, 20 to 25, and 31 to 33 ; January 1901).— With 

 woodcuts.— C. T. D. 



Lilium candidum Culture. Anon. {Gard. Mag. 2472, p. 1G2; 

 16/3/1901). — An instructive note on the treatment of this capricious 

 Lily. The note emphasises the importance of planting the bulbs immedi- 

 ately they are lifted, the time for which is not stated. The accompanying 

 illustration represents an exceptionally fine group of flowering plants of 

 this Lily, two years planted, in Mrs. Kingsley's garden at Bourne Orchard, 

 Hertford. She states that she finds dry bulbs are slow in becoming 

 established and liable to become diseased. She obtains clumps of bulbs 

 from cottage gardens and replants at once, and each autumn applies a 

 dressing of road sand and short manure to the bed. — W. G. 



Lilium Humboldti. By E. H. (/o^mi. iJor^. 2735, p. 176; 28/2/ 1901 ; 

 fig.). — Dealing with the cultivation of this attractive Lily, and showing 

 that it is not difficult to manage when established, but certainly not an 

 easy one to establish. — W. W. 



Lilium Kellogrgii {Garden, p. 331; 11/5/1901; fig.) A 

 native of California, discovered by H. N. Bolander ; named after Dr. 

 Albert Kellogg, a Californian botanist. — H. J. C. 



Lilium kewense (L. Brownii chloraster x L. Henryi) {Gard. 

 Chron. p. 110, and plate; 16/2/1901). — The cross was mside in July 

 1897, and the hybrid flowered in July 1900.— G. S. S. 



Lin aria vulgaris, Beobachtungen und Culturversuche iibcr eine 

 Bliithen-anomalie. By Anton J. M. Garjeanne. {Flora, 1891, Pt. 1, p. 77, 

 figs, ix., X. diagrammatic curves.) — The anomaly was the presence of cata- 

 corollar lobes in varying numbers present in 10 per cent, of a culture 

 made in '98, the flowers often distinguishable by the presence of an 

 exceptionally large axillant bract. The anatomical structure of these 

 lobes is almost the same as the petals ; the histogeny is the same. On 

 raising seed from flowers already set at the beginning of the observations, 

 only 3*7 per cent, (out of 3,028 flowers) showed the anomaly. The results 

 of crosses between flowers with the same or dift'erent numbers of extra 

 lobes showed that the intensity of the anomaly in the oflspring depends 

 more on that of the male parent than on the female. The numbers 1 and 

 3 are commoner than 2, 4, 5 for the extra lobes. They appear especiallv
