If we repeat the mean monthly climatic data of Burma and add the 

 flowering times as observed in the same country, we get this fable. 



Plate IV gives a graphic representation of the foregoing data. 



The main features of these curves are essentially the same, and there is 

 nothing of greater importance that could be deduced from them. A 

 comparison, however, of the graphic representations of Bombay and 

 Burma on the one hand, and of North- West ami Central India and the 

 Upper Gangetic Plain on the other, exhibits a striking difference be- 

 tween the two, which needs an explanation. In Bombay and Burma the 

 minimum of flowering times of the woody plants coincides with the 

 maxima of the hydrometeors in July, whilst in the other regions the 

 minimum of flowering times is reached in October ; that means more or 

 less three months after the maxima of rain, clouds, and humidity. When 

 trying to account for this remarkable fact we must not forget that near- 

 ly the whole of Bombay and Burma are situated within the trc pics, 

 whilst the greatest part of North- West and Central India and of the 

 Upper Gangetic plain belongs to the temperate zone, which is marked by 

 much greater variations oi temperature. Though we seemed to neglect 

 temperature when discussing Bombay, it was not our intention to
