must lapse. It is likely that terms indicative of differential multiplica-

 be produced. 



EXPLANATION OF PLATE XL. 



Fig. 1. Photograph of the flowering stalks of two cretins. The flowers are here as fully 



opened as they usually become in this variety, and they are represented slightly 



smaller than natural size. 

 Fig. 2. Flower of cretin which has larger petals than usual. The standard however is not 



elevated and the straight stigma protrudes beyond the rest of the flower. 

 Fig. 3. In the centre two flowers from a cretin in which, the standards are fully elevated. 



On the right are two other mature flowers from the same plant shewing petals of the 



usual cretin form. On the left are two old buds.
