are the usually gray tops of the deciduous and the dark green of the ever- 
green trees, and, on the other, the brown tone which accentuates the 
irregularity of the profile, and so, when it is viewed from a distance at 
an angle, the park-like nature of the formation is strikingly shown. 
The floristic composition varies. Where it borders on the next one 
above, it partakes of the nature of the latter and imperceptibly grades 
into it. In a plot 2 kilometers inland, at an altitude of 30 meters, 
Albizzia procera forms a conspicuous element, but, so far as my obser- 
vations go, this is the only tree which remains deciduous throughout 
the dry season. Besides Parkia roxburghii, the other trees prominent in 
this plot are Oroxylum indicum, Zizyphus zonulatus, Bombax ceiba, 
Lagerstremia speciosa, Canarium villosum, Anisoptera vidaliana, Ptero- 
cymbium tinctorium, Ficus variegata, Koordersiodendron pinnatum, 
Wrightia laniti, Adenanthera pavonina, Albizzia saponaria, Premna 
cumingiana, Mangifera altissima, A phananthe philippinensis, Artocarpus 
communis, and Buchanania florida. Among the smaller ones are Meme- 
cylon edule, Streblus asper, Cyclostemon bordenti, Mallotus philippinensis, 
and others. Some of the ones mentioned above are deciduous during a 
portion of the dry season, while others are continuously green, but then 
they have a much lesser area of foliage than is found during the favor- 
able time of the year. Nearer the Anisoptera-Strombosia formation in 
addition to the species just mentioned are Shorea guiso, Dipterocarpus 
vernicifluus, Huphoria cinerea, Strombosia philippinensis, Aglaia harm- 
siana, Evodia glabra, and Talauma villariana. The less frequent trees 
are Hndospermum peltatum, Dracontomelum cumingianum, Illipe rami- 
flora, Sterculia oblongata, Myristica philippensis, Gonocaryum tarla- 
cense, Parinarium griffithianum, Palaquium tenuipetiolatum, Macaranga 
bicolor, M. tanarius, Carallia integerrina, Alstonia scholaris, and others. 
All the species in these last two lists are evergreen throughout the dry 
season with this exception, that some of them may be completely deciduous 
for a day or two. All of them show less leaf surface during this time, and 
the deciduous element is nearly as striking as it is in the region nearer 
the shore. 
The type of the Bambusa-Parkia formation, which has just been 
described probably occupies one-third of the area mapped as such. The 
other two-thirds come under sub-formations which are considered to be 
stages in development. As already indicated, isolated groups of bamboo 
are present throughout and these may or may not be accompanied by 
the dicotyledinous species named above. The closed bamboo forest does 
not approach nearer than 14 kilometers to the shore, though “boho” and 
other bamboos are present near the coast line. One of these, Bambusa 
blumeana, probably an exotic form, is the species used in building opera- 
tions in the Philippines. It is the tallest of the bamboos, and with 
its pagoda-like growth forms the most conspicuous feature overtopping 
the low, shrubby vegetation near the seashore. Whenever the “colonies”
