Fungi : Index Bibliographique. " Des Principaux Memoires de 

 Mycologie parus en 1901 " (Bull. Soc. Myc. Fr. xviii. fasc. 2 ; 1902).— 

 A very useful enumeration of the books, memoirs, and contributions to 

 the study of mycology, which were published during the year 1901. 



M. C. C. 



Galanthus Alleni. By W. Irving (Garden, No. 1581, p. 157). — A 

 description, with illustration, of this rare and handsome Snowdrop, which 

 was sent to Mr. Allen, the well-known Snowdrop enthusiast, from 

 Austria in 1883 by Herr Gusenus. — E. T. C. 



Genistas. By G. G. (Gard. Mag. No. 2518, p. 69; 1/2/1902).— 

 A descriptive account of a few species that can be grown in the open air in 

 these islands, but which are not hardy in all parts. Half a dozen species are 

 described, and the list might be extended to include the pretty G. radiata, 

 G. sagittalis, and G. virgata from Madeira, the last-named being the only 

 species that will thrive and flower well under the shade of trees, and is 

 especially valuable as flowering in late summer when so few open-air 

 shrubs flower. It is also known as G. data. — W. G. 



Germination, Influence of Manures on. By G. W. Hicks 

 (Ann. Agr. p. 385 ; August 1901). — Chloride of potash and nitrate of soda 

 used at one per cent, mixed with soil injured germination considerably. 

 Phosphatic and calcareous manures are much less harmful, and if not in 

 too large a quantity have no action. Chemical manures should not come 

 in contact with the seed. Manures are most harmful to the young stems 

 coming out of the seed before they emerge from the soil. It seems 

 probable that no manure used in agriculture aids germination. — G. H. H. 



Ginseng" Culture. By the Editor (Qu. Agr. Journ. x. pp. 121-122 ; 

 February 1902). — The cultivation of Ginseng (Panax Ginseng) for its 

 root is recommended for tropical or subtropical countries. An authority 

 quoted states : " My lowest estimate on an acre planted in Ginseng, and 

 allowed to grow for five years, at the price it is sold to-day, is £7,000 for 

 roots alone, besides the seed crop." — M. C. C. 



Gladioli, Culture Of. By Rev. H. H. D'ombrain (Garden, No. 1585, 

 p. 222 ; 5/4/1902).— The experience of one who has grown the ganda- 

 vensis section of Gladiolus for forty-five years, who considers their culti- 

 vation a puzzling matter, and who proceeds to give much sound and 

 interesting information on the subject. — E. T. C. 



Graft, Curious Result Of a. By H. Danthenay (Bev. Hort. 

 pp. 16-18 ; January 1, 1902). — One woodcut depicting two neighbouring 

 Apple trees at Bougival, with adjoining branches inarched either naturally 

 by contact or artificially, not recorded which. Subsequently to the union 

 one of the trees when in full leaf and fruit was snapped off at the ground 

 line (probably at the original grafting point) in a storm. It was raised 

 and supported on a flat stone beneath the trunk, and not only did 

 it not flag, but it retained its foliage and its fruit continued to grow, 

 though it was solely dependent upon the roots of the other tree and the
