stantially lowered, if we were able to follow one bud through 
the whole period. I thus come to the result, that the whole

SEASON OF FLOWERING. 
The 7 fresh flowers, which I have seen, were all observed 
between 26/3 and 22/7 1920, but at this latest date I found 
several buds of all sizes upon the vines. What will be their 
fate? lf they do complete their development, the flowering 
period of the Rafflesia will occupy the largest part of the year. 
I do not know if this is the case. I only can state, that in the 
region visited by me buds entered the flowering stage during 
the period from March to July.
