AXTHBACXOSE OF THE MANGO IN FLOEIDA. 11 
bore 9.21S flowers, of which 8,-407 were st animate and Sll perfect, 
and the five seedling panicles bore 2,429 flowers, of which 1,022 were 
staminate and 1,407 perfect. 
The flowers are opening continuously throughout the day and 
night, and after opening retain their fresh appearance for about two 
days. The staminate flowers wither and drop off the third or fourth 
day, while the ovaries of the "perfect flowers generally begin to take 
on a dark-green color on the third day, 
A peculiar condition is observed when panicles bearing freshly 
opened flowers are removed from the tree. Within 15 to 30 minutes 
the pistil and stamen of each perfect flower curve toward each other 
and frequently meet, and in some cases wrap themselves together. 
Fig. 1.— Complete mango flowers, much enlarged : A, A freshly opened flower; B and C, flowers which 
have been removed from the tree for 30 minutes, showing the flexing of the stamen and pistil. 
This condition has never been observed on the tree and is not thought 
to have any bearing on the fertilizing processes of the flower. Fig- 
ure 1, A, shows a freshly opened flower., and figure 1. B and C\ shows 
the flexing of the stamen and pistil after the flower has been re- 
moved from the tree. 
RELATIONS OF WEATHER CONDITIONS TO THE DISEASE. 
That there is a very definite relation between weather conditions 
and the productiveness of the mango has been observed by various 
writers. 
Fawcett and Harris, 1 writing of the mango in Jamaica, have the 
following to say on this point: 
Although the mango grows freely everywhere, it is not a fruitful tree in every dis- 
trict; in the southern plains and the low. dry limestone hills it produces enormous 
crops year after year, and very often two crops a year, the main crop from May to 
August, and the second crop later in the year. * * * In humid districts and 
along the northern coast the tree is not at all fruitful, except in very dry years, and 
in the wet districts like Castleton it rarely fruits.
