4. Var. Bhagal/puriensis. 



Stem and petiole gveen with some red, pulviims green, calyx 

 green with red splashes, slightly more obtuse and more twisted 

 than in any of the other three varieties, flowers on withering turn 

 pink. 



With the exception of the slight difference in the form of the 

 calyx in var. Bhagalfuriensis these four varieties are absolutely 

 identical in all morphological and agricultural characters. They 

 flower at the same time, grow to the same height and are 

 equally rol)ust. The only difference between them is one of 

 colour. 



The existence of two intermediate forms with small amounts 

 of colour, quite differently located appears to indicate that the 

 factors concerned in the occurrence of colour in this species are 

 very numerous. Besides the main distinctions given m the synop- 

 sis of the varieties many smaller differences in the localisation 

 occur. It is interesting to note that in the var. intennedius in 

 which tlie flower resembles that of var. ruber in every respect, 

 the corolla nevertheless reniains yellow on withering instead of 

 turning pink. In var. Bhagalpxriensis where there are differences 

 in the colour of the pollen and of the eye the corolla turns pink 

 like that of var. ruber. The tendency of the petal to change colour 

 on fading would appear to be a definite character. 



In the following table all the differences between the two 

 intermediate varieties ai'e given.
