Abstract

The trees and other woody perennials were the most dominant group of understory vegetation. They were predominated by the secondary forest species represented by Ficus botryocarpa, Connarus semide—candrus, Guioa sp. x and y, Canthium sp., and Syzygium sp. The primery forest species were represented by the dipterocarps Hones philippioensis and Parashorea malaanonan. The most common herbaceous plants are Mapania cuspidata and a species belonging to family Zingiberaceae. Crudia sE. was the dominant vine species present. The number of species encountered was higher during the dry than the rainy season. There were 42 new species observed during the dry season while 20 species present during the rainy season were absent in the dry season. Forty two species were observed common to both seasons. Variation in microenvironmental conditions were also noted between seaso,3. The indices of divert, and evenness were relatively high while dominance was low. Thi3 would imply species richness in the community and the adaptability the environment for the growth of a large number of species population..
