A. Simonii (Japan) does very well near water, A. Fortunei (Japan), a 

 well-known variety, Phyllostachys nigra (Japan) beautiful when 

 grown as a specimen plant, P. Quiloi (Japan) requires sun, P. flexuosa 

 very desirable when grown as an isolated plant, P. viridi-glaucescens 

 (China) suitable for parks, P. aurea (Japan) strongly recommended j

Beans, Variation of Varieties of, in their susceptibility to j 



Anthracnose. By M. F. Barrus (PhytopatJiology , i. 6, pp. 190-5). — ( 



Various reports have been made that certain varieties of bean were 

 not susceptible to attack by the fungus Colletotrichum Lindemuthi- 

 anum. The author has investigated the question of immunity for a 

 number of varieties and has failed to find one that under all circum- 

 stances was capable of resisting the attack of the fungus. He finds 

 different " strains " of the fungus varying from one another in some 

 measure in their powers of attacking bean varieties. Dolichos sesqui- 

 pedalis and Vicia Faha were not infected, but Phaseolus multiflorus and 

 two varieties of P. lunatus were infected as well as a large number of 

 varieties of the bean usually attacked, P. vulgaris, the dwarf French 

 bean.— F. J. C. 



Begronia *Aurore.' By Charles Pynaert {Piev. Hort. Beige, 

 p. 37, Feb. 1, 1911; plate).— A. Toeffart, of Destelbergen-lez-Gand, 

 has produced a new Begonia, a hybrid between B. socotrana and 



B. Pearcei, which is said to be a valuable acquisition. The flower is 

 copper-yellow, and the growth of the plant is like that of * Gloire de 

 Lorraine,' only that the leaves are longer and dark green in colour, and 

 the flowers are larger. The blooms are said to be much less perishable 

 and to carry better than those of some other varieties. — M. L. H. 



Biological Statistics {Beih. Bot. Cent. Bd. 27, Abt. ii. Heft 1, 

 pp. 171-206(i). — This is a translation of C. Eaunkiaer's paper in the 

 " Botanick Tidskrift," Bd. 29, Heft 1. The paper deals chiefly with 

 the statistics of winter buds (upright branches, branches near the 

 earth, close to the soil, under the earth, and annual plants). Stem 

 succulents, epiphytes, large or moderate-sized plants, small plants, and 

 dwarf plants are also distinguished. 



The author then tabulates the plants of various floras — Seychelles, 

 St. Thomas, South Labrador, Baffin's Land, &c. — and endeavours to 

 obtain a characteristic climatic series of adaptations. The northern 

 Arctic region is specially treated. 



A percentage division of the species, according to life-forms, is 

 shown in these tables. The only general result obtained is a suggestion 

 that there are four chief climates — tropical, sub-tropical (winter rain), 

 cold-temperate, and cold 'zones. — G. F. S. E.
