PHILOSOPHICAL NOTES ON 



Fig. 155. Sheath of Tangerine Orange partially removed. 



Fig. 156. Ovary of Orange after fertilization, the style anrl stigma dropping 



off at (a). 



For this opportunity I am in(lel>ted to my friends Messrs. Kelway 

 and Son of Langport. 



Tlie following is a resume of my oV)servations. 



In tlie single P. Moutan the sheath completely envelops the 

 carpels, with the exception of the stygmatic surfaces. In some cases 

 it encroaches also on the stygmatic surfaces. It is purple both 

 on its outer and inner surfaces. Tliis corresponds witlithe colour 

 of the stamen -filaments. 



In a semi-double Japanese variety, nam.ed " Mrs. William 

 Kelway," the petals are pure white, and the sheath is also white, 

 whih' the .stamen-filaments are also white. 



In the single varieties the surface of the sheath is distinctly 

 furrowed longitudinally, as if it were made up of an agghitination 

 of filaments, the tips remaining free round the stigmas of the 

 carpels.
