As one would naturally suppose, this forest is more open than 

 the lauan type, consequently the jungle growth consists of tan- 

 gles of rattan and other large vines. However, mature subtypes 

 are comparatively free from jungle growth. 



Erect palms are constantly present. The Mondoro portion 

 of it, above described, shows 66.5 palms to the hectare* (not in- 

 cluding young ones without stems), composed of six different 

 species. The lowlands near the mouths of rivers at the head of 

 Davao Gulf (Mindanao) will show even a larger stand. 



As the lauan-hagachac type occurs on land sought for agricul- 

 tural purposes, especially for the cultivation of rice, the area oc- 



* I hectare equals 2.47 acres.
