Tims 0. Lamarckiana agrees with 0. biennis in certain 

 features of the flowers, while agreeing equally with O. 

 (fvundi flora in certain other features. We know that 

 these three species when crossed give more or less Mended 

 or intermediate hybrids, as appears to be frequently the 

 case in crosses between "Linmean'' species. 7 This being 

 the case, we should not expect to derive 0. Lamarckiana 

 from a cross between the ordinary races of 0. biennis and 

 0. grandiflora, for this would imply alternative rather 

 than blended inheritance of the various flower charac- 

 ters. Davis has not taken into account the important dif- 

 ferentiating features between the buds of 0. Lamarcki- 

 ana and 0. grandiflora, merely telling us that the 1 ' in- 

 florescence was very similar to 0. Lamarckiana/' and 

 that "the only essential difference between the buds lay- 

 in the slightly greater attenuation of the sepal tips." 

 But his hybrids can not be, as he states, and as would be 

 anticipated from the results of similar crosses in oeno-
