Abstract: Plants are remarkable source of valuable substances for human beings. These are showing variation in their habitat as well as their habit. As per climatic conditions, the plants are showing their presence in different sites. Climbing plants account for a significant component of plant evolution, diversity and abundance and play a major role in forest communities and ecosystems. The survey of angiospermic ornamental climbers from Kattathurai panchayath recorded total 48 species under 27 genera belonging to 17 families. Maximum number of 11 species was recorded for dicotyledonous family Convolvulaceae (Ipomea-11) followed by Jasminum (3), Passiflora (3), Clerodendrum (3), Allamanda (2); Campis (2); Clematis (2); Clytostoma (2); Solanum (2). Climbers in different parts of India suggest that the climbers are the main components of ecosystem, and their conservation is important to establish their appropriate utilization. The abundance of climbing plants in this study area was directly related to their capacity to intercept light efficiently but not to their potential carbon gain. The most abundant climbers in this ecosystem match well with a shade-tolerance syndrome in contrast to the pioneer-like nature of climbers observed in tropical studies.
