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.)

nates, or a grand total of 4,222. 
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,
