DISEASES OF PLANTS. 



Pathological plant anatomy, E. Kuster {Pathologische Pflanzenanatomie. 

 Jena: G. Fischer, 1916, 2. cd., pp. XI+U7, fujs. 209).— The author presents in 

 this edition not only the material retained from the former one, which has been 

 translated by Miss Dorrance (E. S. R., 34, p. 49), but also a considerable amount 

 of new material, with a rearrangement of the general plan, bringing the work 

 up to the date of its practical completion about August, 1914. There is also 

 added a list of recent contributions by other authors extending to November, 

 1915. 



Tumors in plants, E. F. Smith (Science, n. ser., ^// {1916), No. 1139, pp. 611, 

 612). — The author reports having succeeded in producing small tumors in 

 plants without the use of the crown gall organism (Bacterium tumefaciens) by 

 means of substances which are by-products of bacterial growth. Small tumors 

 are said to have been obtained repeatedly on several kinds of plants, and their 

 presence is interpreted as being due to the fleeting chemical stimulus applied. 



A paper describing in full the investigation is promised for early publication. 



How to identify infectious plant diseases, S. F. Ashby (Jour. Jamaica Agr. 

 Soc, 20 (1916), No. 1, pp. 6-12). — This information, said to be available also in 

 pamphlet form, relates, among other matters, to the symptoms, causation, and 

 treatment of Panama disease or banana wilt, Bonnygate disease or banana bulb 

 rot, cacao pod rot and red or purple canker, dieback of cacao, bud rot of coco- 

 nut palm, and leaf dieback of coconut. 



Report of the division of botany, H. T. GtJssow (Canada Expt. Farms Rpts. 

 1915, pp. 0J,9 990, pis. 11, fiijs. 2). —An account is given of some administrative
