STUDIES IN THE VEGETATION OF THE PHILIPPINES, I. 717 
These figures show the bulk of clipterocarps to be uot so high here as 
in some other forests, yet the preponderance of that family is still too 
apparent to be overlooked. 
The following, giving some idea of the composition of the forest, is 
a list of the principal trees other than those mentioned in the yield and 
stand tables : 
FAGACEAE-QweroMs sp. ; Ulmaceae- G e Itis sp. ; Moraceae -Artocarpus communis 
Forst. ; AnoAACEAE-Canangium odoratum Baill. ; Myristicaceae-M yristica spp. ; 
~RosACEAE-Parinarium griffithianum Benth.; B xmsEiiACEAE-Canariurn spp.; Legu- 
minosae -Erythrophloeum densifiorum (Elmer) Merr., Albizsia saponaria Blume; 
EuPHORBiACEAE-Oi/ctosiewow spp.; ANACARDiACEAE-Koordersiodendron pinnatum 
Merr.; SAPiNDACEAE-.BMp7toH» cinerea Badlk., Pometia pinnata Forst.; Rhamna- 
CEAE-Zizyphus zonulatus Blanco; TiLJACEAE-Greioia stylocarpa Warb. ; Stercu- 
ZJACEAE-Pterospermum spp., Pterocymbium tinctorium Merr. ; GuTTiFEEAE-f/alo- 
phyllum spp., Garcinia spp. ; DiPTEROCARPACEAE-IIopea spp., Anisoptera sp. ; 
LiYTiiRACEAE-Lagerstroemia piriformis Koehne; CoMBRETACEAE-Terminalia nitens 
Presl; MrRTACEAE-Eugenia spp.; Sapotaceae -Palaquium spp.; Ebenaceae-ZH'os- 
pyros spp.; ArocYNACEAE-TFrigMia laniti Merr.; VER'BENACEAE-Uitea; littoralis 
Decne., Vitex aherniana Merr.; B,VBiACEAE-8arcocephalus cordatus Miq. 
FORESTS OF LEYTE, MINDORO, AND VARIOUS PARTS OF LUZON, AND 
■ MINDANAO. 
Bough estimates of timber made in the Davao District of Mindanao 
.show also the predominance of dipterocarps. On the Island of Samal 
near Davao, at least 80 per cent of the volume of the forest is composed 
of dipterocarps, mainly Pentacme contorta Merr. & Eolfe, Parashorea 
plicata Brandis, and Shorea guiso Blume. Untouched forests on the 
mainland at the head of Davao Gulf showed the dipterocarp forests reach- 
ing to the tide-water in many places and even occupying all but the 
frontal zones of the beaches. 
The above represent regions in which more or less detailed studies 
have been made by the author. More hurried trips made in the Provinces 
of Tayabas and Camarines on the Island of Luzon, in the District of 
Zamboanga on the Island of Mindanao, and on the Island of Leyte, show 
that the large bodies of forest are composed of dipterocarps in greater 
or less proportion usually running over on an average 70 to 80 per cent 
of the bulk. The published work of Merritt 8 for Mindoro and the 
unpublished results of Curran, Hagger, Klemme, and other foresters in 
the Bureau of Forestry for various parts of the Island of Luzon, of 
Hutchinson for parts of Mindanao, and of Eosenbluth for northern Leyte, 
give results in entire confirmation of those mentioned above.
