Qualitative field surveys were conducted to record the woody plant (tree, shrub, and liana) wealth in Karumpuliyuthu Hill, Tenkasi district, Tamil Nadu. All the recorded species were confirmed with regional floras. The qualitative field survey allowed us to record 42 species in 32 genera and 19 families. The family Fabaceae had a large number of species (13 species) in the study area. The present study adds valuable information about the occurrence of 42 woody plant species in a tropical thorn forest ecosystem. The woody plant community is dominated by native plants, and only three are introduced. Nearly half of the recorded species produce fleshy fruits, thus providing food to small mammals and birds.
