POLLINATION OF THE MANGO.

crops, with several fruits arising from a panicle, has a high percentage 

 of perfect flowers. Most of the Indian varieties, which commonly 

 mature but one fruit from a panicle of flowers, usually have a lower 

 percentage of perfect flowers than either the No. 11 or the Philippine 

 race of seedlings. The Haden, however, has a large percentage of 

 perfect flowers and retains the bearing habit of the Indian varieties, 

 though occasionally it matures more than one fruit on a panicle. 

 The Julie, which has a very high percentage of perfect flowers, com- 

 monly matures but one fruit on a panicle. It seems very doubtful 

 whether there is any correlation between the percentage of perfect 

 flowers and productiveness. 



In some varieties, at least, the perfect flowers do not open con- 

 tinuously during the time the panicle is in flower, but most of them 

 appear within a limited period of time. This is illustrated by a 

 count made of one panicle of Sandersha flowers, showing the number 

 of perfect and staminate flowers which opened each day. (Table I.)

DISTRIBUTION OF PERFECT FLOWERS ON THE PANICLE. 



When only a small number of perfect flowers are produced, as in 

 such varieties as the Mullgoa, Kistapal, and Salamar, in which 5 to 

 50 have been counted on one panicle, these flowers usually are pro- 

 duced upon the apex of the main axis of the panicle, with often a 

 few upon the uppermost lateral branches. As the proportion of per- 

 fect flowers increases they are found farther down upon the panicle, and 

 in many varieties they occur even upon the lowest lateral branches,
