alpicola had ovary far backward in development. This at once 

 suggests that Dr. Hayata must have been led to the conclusion 

 that the ovary of P. alpicola was depressed conical. As a mat- 

 ter of fact the ovary of P. alpicola does not essentially differ 

 from that of P. simplex in shape and size. As to the other 

 characters the writer mainly agrees with Dr. Hayata except for 

 the statement that the stems of P. simplex be usualh' solitary 

 and those of P. alpicola are 3-fasciculate. In either species the 

 stems are solitary as a rule and less frequently fasciculate.

 11. Mature ovary. All X 5. 



Another diagnostic character, though not having been 

 hitherto pointed out, is the nervation in the sepals and petals. 

 As may be seen in the text-figures, the sepals and petals of P. 

 simplex are provided as a rule with fewer veins than those 

 present in the same organs of the other plant. This character 

 as well as the size of sepals and petals however vary within a 

 certain limit. In addition the staminodes of both the species 

 vary as regards the incision and size to some Extent.,
