xu,c,é Brown: Mount Banahao’s Podocarpus Imbricatus 319 
quadrasianum Vid., a larger epiphyte, occurs in much smaller 
numbers. 
On the ground there are large numbers of small seedlings of 
Podocarpus imbricatus, but most of the other individuals of this 
species are more than 10 centimeters in diameter, while trees 
of Podocarpus less than 5 centimeters in diameter are very 
rare. This would indicate that seedlings of Podocarpus imbri- 
catus do not readily survive under a mature stand. 
The rainfall on the northern and northeastern slopes of Mount 
Banahao is distributed throughout all the months of the year, 
and there are no distinct wet and dry seasons. 
The northeast monsoon strikes the Islands on the eastern coast. 
As there are no high mountain masses northeast of Mount Bana- 
hao, this monsoon brings heavy rains to the northern and north- 
eastern slopes of the mountain. The moisture carried by the 
northeast monsoon is largely deposited on the eastern half of 
the Islands; and the monsoon continues over the western half 
of the Archipelago as a drying wind, which results in a marked 
dry season in the latter region. The southwest monsoon is not 
nearly so strong as the northeast monsoon, and although it 
brings rains on the western side of the Archipelago, much of 
the rain which comes at this season of the year is the result of 
the cyclonic disturbances (typhoons), which cause the deposition 
of rains on both sides of the Islands. Therefore, also during 
this season, heavy rains occur on the northern slopes of Mount 
Banahao. 
Owing to the difficulty of making trips to the top of Mount 
-Banahao to obtain regular records of climatic condition, the 
writer was compelled to have most of this work done by an 
assistant, Macario Ocampo, who had had no scientific training. 
For this reason the only instruments employed were a rain gauge, 
a recording thermometer, and a recording hygrometer. The 
results obtained from these are probably about as accurate as 
would be expected from the instruments as the reading of a 
rain gauge is very simple and the records from the hygrometer 
and thermometer were checked by the writer at various times. 
The hygrometer and thermometer were in a case with louver 
sides and a lattice bottom and were about 75 centimeters above 
the ground. : 
The rain gauge was placed in the top of a dominant Podocarpus 
and was read weekly. The results are given in Table I. An 
examination of this table shows at once that the rainfall is heavy 
and is distributed throughout the entire year. The rainfall at ,
