eye equally encompasses both the eastern and western coast for 
about one third of its southern portion. The table lands of 
Bohol are also visible. 
Nearly all my collecting was done along the Bonyao 
river which heads at the foot of the perpendicular north- 
eastern side of the mountain; and along the ridges and 
spurs to the south and north of this river. There is an 
old beaten but steep and rough trail up the southern spur 
clear to the highest peak. The trail leading up the northern 
spur or ridge is not as steep and leads through some fine 
woods from 3500 to 4500 feet. At about 4000 feet elevation 
is a splendid spring right on the trail and in very humid 
woods. This trail terminates on the lesser peak which is about 
150 feet below the highest one. The highest peak lies to 
the south of the lesser one and there is no trail connection 
over the rather sharp deep depression between them. 
The prevailing winds are from the Sulu sea toward the north- 
east. During the monsoon season occasionally the winds blow from 
the opposite direction and are usually more stormy. The climate 
for the entire year issaid to be comparatively uniform. Marcb, 
April, May, and June have the least rain. Even during these 
months there is a great deal of fog rolling in over the mountains 
from the Sulu sea. The lowest limit of this fog altitude on 
the Dumaguete side is approximately at 3500 feet. 
At this point the higher valley plants give way to an entirely 
new flora. Nowhere else in the Philippines have 1 encountered 
such an abrupt and complete change. Here the splendid tree 
ferns begin and extend clear to the summit. Freycinetia ne- 
grosensis Merr., Polygala venenosa Juss., monstrous trees of Aga- 
this philippinensis Warb., afew new species of Macaranga, Ficus 
disticha Bim. abound, and are nearly all limited to within a 
1000 feet altitudinal range. Many other species of this altitude 
extend much higher if not quite to the summit. Others give 
way to closely allied forms at the top. In other words, the flora 
from 3500 feet up to the summit has a striking unity when 
compared with that below said elevation. The summit vegeta- 
tion is dense in Freycinetia jungles and rigid interlaced shrubs, 
profusely rich in scale mosses. The latter loosely cover every- 
thing. On the larger limbs of spreading trees they form big 
clumps, twigs the size of a man’s finger they clothe until they
