Tamarind . — Tamar Indus indicus no doubt found its way Here 
many years ago but whether regarded as a dye, drug, or condiment 
the local supply is furnished by Indian bazaars. 
Cola acuminata and C. vera. — The Cola-nuts were introduced in 
1 88 1 and not soldom sent to the Native States. Cola acuminata 
has been cultivated for many years in Johore and Negri Sembilan, 
and has fruited well in both places. There are, however, only a few 
trees scattered about the Peninsula. 
Brucea sumatrana, “Kosam,” was first obtained by Dr. WALUCH 
in Singapore, where it still exists in a wild state, though very scarce 
owing to the ground it inhabited being built on. It had practically 
disappeared from the Colony when MuRTON reintroduced it from 
Hongkong, in 1875, and I reintroduced it again from Pahang in 
1890; since then, considerable attention has been called to it as a 
drug for dysentery and a large number of plants were propagated 
in the Botanic Gardens, and seeds distributed in 1901 to all the 
District Officers in the Federated Malay States (although the plant 
is quite common in*the Federated Malay States) and elsewhere, and 
a quantity sent to India and other parts of the empire. Reports 
of experiments made with it have already been published in the 
Bulletin. 
Ociinum viride, the “Mosquito-plant,” obtained a great noto- 
riety in 1903 as a deterrent of Mosquitos in Central and West 
Africa. The Botanic Gardens Department, having several valued 
correspondents in Tropical Africa, had no difficulty in getting two 
lots of seeds within a couple of months of the publication of the 
supposed use of the plant. These were cultivated and seeds from 
them were distributed to all parts of the Malay States and elsewhere 
in six months. 
The plant proved useless, but the rapidity with which the plant 
was obtained, propagated and freely distributed all over the Penin- 
sula illustrates the value of building up and keeping up an extensive 
correspondence with all parts of the world. It is said that another 
Botanic Garden, 1 s fortunately supplied with correspondents, only 
obtained 12 seeds t m a dealer at a high price by the time that the 
plant was being distributed in quantity all over the Peninsula. 
Coca, Erythroxylon Coca and E. novo-granatense , was first in- 
troduced by MuRTON in 1875, and several forms at a later date. It 
grows with great ease and rapidity, and being very prolific is very 
quickly propagated. It has been supplied to a large number of 
estates in the Malay Peninsula, and is now scattered about every- 
where. The demand for the leaf is small, however, and the plant is 
so readily grown that it is seldom really remunerative. 
Cinchona . — The Quinine trees were introduced by MURTON in 1878, 
{< Cinchona officinalis ), (C. calisaya ) in 1879 as well as other species. 
Sir Hugh Low also procured C. succirubra from India, and tried 
it at the Hermitage, Waterloo Estate, and on Thaiping Hills. The 
result, however, proved a failure. The plants grew to bushes, seeded 
freely and on the Thaiping Hills became naturalized, but failed to
