WRIGHT: FOLIAR PERIODICITY 
Anogeissus latifolia. —A common tree in South and Central 
India ; is leafless during the greater part of the dry season ; 
from November the old leaves acquire a copper tint, fall in 
February, and new leaves appear in May. 
Pongamia glabra .—Common in South and Central India, 
Burma, and Bengal; drops its leaves in April, but new leaves 
appear quickly. 
Eugenia Jarnbolana. —This species is common in India ; 
the new leaves are produced in March ; in the Punjab the tree 
is not evergreen, the old leaves being shed in January and the 
new leaves appearing in March to May. 
Eugenia operculata. —Common in parts of India ; puts on 
its new foliage in April- 
Shorea robusta , Gaertn., common in parts of India ; is 
never quite leafless, but produces abundance of foliage in 
March. 
Ficus bengalensis, F. infectoria, Ficus glomerata, and 
F. hispida ; common in various parts of India : undergo their 
leaf change from January to April. 
In concluding this paper I cake the opportunity of 
expressing my gratitude to Dr. J. C. Willis, Peradeniya, for 
first suggesting the subject on my arrival in Ceylon and for 
help repeatedly given ; to Dr. Treub, Buitenzorg, for much 
information concerning the climate and foliar periodicities 
in Java; to W. Nock, Esq., and H. F. Macmillan, Esq., for 
several notes; to the Surveyor-General, Colombo, for records 
of climate ; and to M. Wright for various translations and 
reading proofs.
