stroying the leaves. Though abundant on wild or full- 
sized trees, it would probably do little harm in the 
cultivated state of the plant ; as the shoots are constantly 
being cut on an estate, insect and fungus pests have less 
chance of establishing themselves than in a tree, where 
the leaves are left on for a long time. 
Cattle, goats, and squirrels are also recorded as 
occasionally doing damage by eating or nibbling the 
shoots. 
Doctors W .and J. van Leeuwen-Reijnvaan, 
in t]\Q Annales du Jardin Botanique, yo\. xxiii.^p. 120, 
plates xxiv., xxv., figure and describe cinnamon leaves 
infected with galls due to a mite known as Eriophyes 
doctersi, Nal. The animal seems only to attack the 
true cinnamon, and it appears to occur in many parts of 
Java. The galls generally appear on the lower side of 
the leaf, rarely on the upper side, but they are also found 
on the leaf-stalk and twigs ; when the plant is badly 
affected the terminal and axillary buds are attacked, 
and the whole shoot is twisted up. They seem to be 
most injurious to young plants. The galls are in the 
form of blunt, hollow cones, and are often densely 
crowded upon the leaves, quite destroying them. This 
class of gall, very abundant in the tropics, is very 
troublesome to deal with. Infected leaves should be 
removed and burnt, and badly attacked seedlings should 
be destroyed. 
Fungi. — Pestalozzia cinnamomi, Raciborski. This 
minute leaf fungus is described in the Bulletin Institut 
Botanique de Buitenzorg, vol. vi. p. 13, as attacking 
twigs and leaves of cinnamon. No account of the 
injury caused by it is given. 
Corticium javanicum. — This fungus, which has 
obtained more notoriety as a pest on the Para rubber tree 
than on any other plant, occasionally attacks cinnamon 
shoots, as it does all manner of woody plants, in the wet 
season. It forms a pale pinkish-white crust on the 
stems of plants, destroying the cambium layer and 
causing the death of the shoot or twig. This fungus is
