oil. A satisfactory attempt at growing tobacco has been made. In 

 Kiao-Chao, in the province of Shantung, farming is actively carried 

 on, yielding large crops of rice, wheat, beans, cotton, tobacco, hemp, 

 and opium. — S. E. W. 



Gentian Seed. By J. T. S. (Garden, Sept. 17, 1910, p. 446).— 

 This seed should be sown early in October. If sown as soon as ripe (the 

 usual recommendation) the seeds lie much longer in the ground than 

 if they are kept for a few weeks. — H. R. D. 



Gipsy Moth Parasite Laboratory, Technical Results from. 



By L. O. Howard, Ph.D. (U.SA, Dep. Agr., Bur. Entom., Tech. 

 ser. 19, pt. i., Jan. 1910; 7 figs.). — This paper deals with the parasites 

 reared, or supposed to have been reared, from the eggs of the gipsy 

 moth, and gives some of the systematic and biological results of the 

 work. It forms the first of a series, and describes several new egg- 

 parasites. — 7. G. J. 



Gladiolus gandavensis 'Europa' {Oester. Gart. Zeit, vol. v. 



pt. X. pp. 365, 366). — ' Europa ' is a gladiolus of healthy growth, with 

 a strong stem, which may bear as many as twenty-four beautiful snow- 

 white flowers, half of which are open at the same time. It is valuable 

 for cut flowers. — S. E. W. 



Gladiolus gandavensis ' Europa.' By F. Eeutersheim (Garten- 

 flora, vol. lix. pt. xxii. pp. 498-500; 1 fig.).— This gladiolus, brought 

 out by W. Pfitzer, of Stuttgart, is valuable as a cut flower, as it is 

 pure white and lasts many days in water. — S. E. W. 



Glass Traps for Insects. By H. Zimmermann (Oester. Gart. 

 Zeit. vol. V. pt. iii. pp. 90-92). — Bottles containing beer, or the special 

 glass traps of Brossart, charged with beer, should be placed in orchards 

 during the summer months, as they capture large numbers of wasps 

 and hornets. — S. E. W. 



Gloeosporium Rot of Bananas and the Spotting- of Ivy Leaves 



by Gloeosporium and Phyllosticta. By E. Laubert (Gartenflora, 

 vol. lix. pt. xix. pp. 409-415; 2 figs. 1 col. plate).— The black marks 

 on banana peel are caused by Gloeosporium attacking the fruit during 

 transport. Every effort should be made to avoid bruising and to keep 

 the bananas cool and dry, giving plenty of ventilation. 



Phyllosticta hedericola causes dark brown spots on ivy-leaves, 

 which, with the aid of a lens are seen to consist of a series of con- 

 centric rings. Gloeosporium paradoxum generally attacks the edge of 

 the leaf, causing a brown discoloration. In either case the leaves 

 should be collected and burned. — S.E.W. ■ / 



Gloxinia, A Double. By Eug. Vallerand (Rev. Hort., June 1, 

 1910, pp. 254-255; col. plate). — The plate depicts a very promising 

 double form of Gloxinia, somewhat resembling a double Petunia, white, 

 sparsely dotted with magenta internally. The plant appears to have
