their control, and gives selections of plants suitable for growing in various

Crossing experiments v/ith canna varieties, J. A. Honing {Rec. Trav. Bot. 

 Neerland., 12 (1915), No. 1-2, pp. 1-26, figs. 2).— Data secured from a study of 

 character inheritance in the joint progeny of tv^'o varieties of cannas are here 

 presented in tabular form and discussed. The results secured from a study of 

 the first two generations indicate that for Canna indica character transmission 

 occurs not only according to Mendel's law, but there are three completely 

 independent lines of inheritance. 



Heredity of color in Phlox drummondii, A. W. Gilbeet (U. 8. Dept. Agr., 

 Jour. Agr. Research, 4 {1915), No. 4, pp. 293-301, pis. 3).— A Mendelian study 

 of color transmission in P. drummondii, conducted at the New Yorli Cornell 

 Station, including a review of our knowledge relative to the nature of color 

 in plants. Commercial seed was purchased and the different varieties grown 

 and self-fertilized for three years so as to be sure of pure types. The varieties 

 used in these experiments were found to breed true for three years and are 

 assumed to be pure. The parents were self-fertilized each year and grown 

 alongside of the Fi and F2 hybrids. The flowers of a number of the seed parents 

 and hybrids are illustrated in color. 



The unit characters found in the four varieties of P. drummondii that were 

 used in these experiments include (1) a dark eye factor producing a dense 

 coloration at the center of the flower. This was dominant over its absence, the 

 white eye, which was exhibited in more or less of a definite pattern. (2) A 

 blue factor. (3) A red factor. (4) An intensifying factor which determines 

 the degree of pigmentation of the reds. (5) A yellow factor v\rhich acts only 

 in the presence of the eye factor. The reds and blues are cell-sap colors, and 

 the yellow is due to the presence of yellow chromoplasts.
