November and December, but as previously stated this is of 
no serious consequence. The months of February and March 
are coincident with the leafless phase of most of the species 
of this group. 
The average length of time during which the trees of this 
group remain leafless is longer than for the members of the 
Ceylon and India group. For instance, we have Bombax 
malabaricum, the most remarkable for its leafless period,* 
which extends with some trees from 79 to 96 days in each 
year; Erythrina indica (21 to 36 days), Gyrocarpus Jacquini 
(29 to 31 days), and species such as Berrya Ammonilla and 
TerminaliaBelerica. The fact that these species are widely 
distributed may yet be correlated with the length of their 
leafless period and the adaptability of this to a hot dry season.
