This difference in the rainfall, amounting to as much as 1, does not appa- 
rently affect the luxuriance or variety of species in any marked degree, 
nor is, to compare with European conditions, a rainfall of 50 inches unusual 
for certain countries, as, for instance, Ireland and some parts of England. 
It is therefore questionable whether the phytogeographical term “ rain 
forest” can be correctly applied in this instance in the wholesale fashion 
which is accepted at the present time for certain tropical areas, and finds 
expression in the sweeping inclusion of a country the size of Borneo in 
one phytogeographical unit. In fact, as regards this country, I should say 
that the rain forest of perpetual moisture and “ drip tips ” is conspicuous 
by its absence. 
Secondary and, to a small extent, primary high forest in Junghuhn’s 
sense are the two prevailing plant-formations of the country. The former 
must be even more pronounced in Dutch Borneo, which I believe carries a 
much denser population and is almost entirely under sporadic clearing and 
cultivation. 
3. GENERAL PLANT-FoRMATIONS. 
Secondary Formations.—It is difficult to speak from our very limited 
knowledge of the general floral conditions of the country investigated, but 
there is no doubt that the whole of the coast region, judging from Motley’s,
