bohnen. (Bot. Zeitung, 1874, v. 32: I 
May, c. 273-283; 8 May, c. 289-302, pl. 5.) 
Experiments on the variation induced in phaseolus 
multifiorus and ph. vulgaris by crossing showed that 
both species are self-fertile, the latter to a greater degree 
than the former. Experiments in artificial crossing of 
varieties gave chiefly negative results, from which the 
writer concludes that crossing is impossible, or at least 
very doubtful. Reference is made to the literature on 
insect-fertilization of the species of phaseolus (c. 295- 
296). W: T. (2768)
