EXPERIMENT STATION RECORD, 



On the inheritance of the yellow tinge in sweet pea coloring, Mrs. M. G. 

 Thoday (Sykes) and D. Tiiouay {I'roc. VamhriUijv Phil. »SVx'., 16 (1!)10), No. 

 1, pp. 7I-8J1). — A descrii)ion is given of experinionts begun in 1!)0G on the nature 

 and inheritance of the yellow tinge in scarlet, siilmon, and dee^) cream-colored 

 sweet-pea Uuwers. Several crosses were made and the offspring grown as far 

 as the F- generation. Those resulting from a cross of Queen Alexandra and 

 Dorothy Eckford were carried on to the Fa and I*\ generations, and the authors 

 describe the segi'egation according to color characteristics. 



The deep yellow tinge in Queen Alexandra, deep salmon, and deep cream 

 sweet-pea flowers was found to depend on 3 coincident recessive characters. 

 Microscopial examination showed that one of the factors imparting a tinge to 

 the whole flower, producing self-colored forms, affects the sap only, tinging 

 it deeply. The second similarly imparts to the sap a tinge which is fainter 

 and is commonly associated with a few yellow ])lastids. The third factor, 

 which chiefly affects the standard, is connectied with the occurence of large 

 clusters of golden-yellow plastids in the cells. 



A spineless mutation of Cynara cardunculus, L. Tbabut {Bui. 80c. Bot. 

 France, 57 {1910), No. 5, pp. 350-35.'f, j}ls. 2). — The author reports the occur- 

 rence in Algeria of a spineless form of the wild cardoon which differs only in 

 the unarmed character of the plant. It is believed that the spineless form 

 will prove a valuable acquisition. 



International catalogue of scientific literature. M — Botany {Internat. 

 Cat. Sci. Lit., 6' {HJIO), pp. VIII+DJ,!)).— This is the eighth edition of the In- 

 ternational Catalogue (E, S. R., 23, p. 431), about 7,500 articles being indexed. 

 The literature is mostly that of 1908, although there are some titles included 

 earlier than that and a few entries of 1909. 



FIELD CROPS. 



A report of seven years' investigation of dry fai-ming methods, L. A. 

 Meeeill {Utah 8ta. Bui. 112, pp. 95-162, figs. 15). — A progress report of the 

 first season's investigations has been previously noted (E. S. R., 16, p. 862).
