514 WRIGHT : FOLIAR PERIODICITY 
(6) Schleichera trijuga is a species which, according to 
Brandis (For. FL, p. 105), sheds its leaves in February, hut 
produces new leaves in March when most of the other trees 
of the dry forest are leafless. 
(7) Spondias mangifera is common in the dry forests of 
many parts of India and Burma, and according to Brandis 
(p. 128) is one of the first trees to shed its leaves and the last 
to renew them, often remaining leafless until the rains have 
set in. The leaves are shed in November, and the flowers 
are produced in April. 
It is interesting to note that most of the above seven 
species undergo defoliation and foliar renewal at approxi¬ 
mately the same time of the year as at Peradeniya, the last 
three species showing almost exact agreement in time of 
periodicity. 
Trees of Bombax malabaricum, Careya arborea, and Cassia 
Fistula, common to South India, Burma, and Bengal, also 
closely agree with trees at Peradeniya in the time of their 
leaf periodicities, as the following notes show. 
Bombax malabaricum is leafless from November or 
December until April, and is covered with flowers from 
February to March, according to Brandis, p. 31. 
Careya arborea .—According to Kurz, (Vol. I., p. 499) this 
is common in all the leaf-shedding forests, especially in the 
open, dry, lower mixed, and savannal forests of Burma ; it is 
leafless during a part of the dry season, the new foliage 
appearing in March and April together with the flowers. 
Cassia Fistula , which is common all over Burma and 
the adjacent leaf-shedding forests, is leafless for a short time 
in the dry season, the new leaves being produced in April 
and May. 
Several other species have been observed to pass through 
a leafless state by Brandis in South India, Burma, and Bengal, 
and among them the following are noted. 
Albizzia stipulata. —The young leaves appear in February 
and March.
